THE AGE OF FLOWERING PLANTS
ANGIOSPERM means "seed borne in vessel," while GYMNOSPERM means "naked seed," a reference to the lack of protective structure enveloping the seed. One reason that flowering plants were able to diversify so dramatically and spread during the Cretaceous and Cenozoic, or modern, the era was the evolution of new structures and tissues such as the carpel, a womb-like vessel that encloses angiosperm seeds and endosperm, a placenta-like tissue that nourishes the young plant as it develop within the seed, Today, angiosperm dominate terrestrial life on the planet. At an estimated 422,000 species, they compose by far the largest group of plants. They grow in greater range of environments, exhibits a wider range of growth habits, and display more variation in form than any living group of plants. In size, angiosperm range from tiny duckweed to eucaplytuses more than 330 ft (100 m) tall. The explosion of angiosperm diversity has gone hand in hand with the proliferation of insect, birds, and other animals that pollinate their flowers, disperse their fruits and seeds, and eat their leaves.

Rudbeckia hirta Linnaeus, 1753 - black-eyed susans in Ohio, USA (25 July 2015).
Plants are multicellular, photosynthesizing eucaryotes. Most species occupy terrestrial environments, but they also occur in freshwater and saltwater aquatic environments. The oldest known land plants in the fossil record are Ordovician to Silurian. Land plant body fossils are known in Silurian sedimentary rocks - they are small and simple plants (e.g., Cooksonia). Fossil root traces in paleosol horizons are known in the Ordovician. During the Devonian, the first trees and forests appeared. Earth's initial forestation event occurred during the Middle to Late Paleozoic. Earth's continents have been partly to mostly covered with forests ever since the Late Devonian. Occasional mass extinction events temporarily removed much of Earth's plant ecosystems - this occurred at the Permian-Triassic boundary (251 million years ago) and the Cretaceous-Tertiary boundary (65 million years ago).
The most conspicuous group of living plants is the angiosperms, the flowering plants. They first unambiguously appeared in the fossil record during the Cretaceous. They quickly dominated Earth's terrestrial ecosystems, and have dominated ever since. This domination was due to the evolutionary success of flowers, which are structures that greatly aid angiosperm reproduction.

Buttonbush is native to the New World. The more common subspecies occurs in much of eastern America and parts of southeastern Canada. The less common California subspecies occurs in parts of California, scattered areas of America's Desert Southwest, plus parts of Central America. Buttonbush flowers are packed in spherical clusters that attract many insects.

En biologie, chez les plantes à fleurs (angiospermes), la fleur constitue l'organe de la reproduction sexuée et l'ensemble des « enveloppes » qui l'entourent. Après la pollinisation, la fleur est fécondée et se transforme en fruit contenant les graines. Les fleurs peuvent être solitaires, mais elles sont le plus souvent regroupées en inflorescences.
Très tôt, les fleurs ont attiré l’attention de l’homme, qui les utilise et les cultive pour la parure (couronne de fleurs), pour l’ornementation intérieure (fleurs coupées, bouquets, ikebana) et extérieure (jardins, plates-bandes, etc.) ainsi que pour leurs odeurs et pigments. Les fleurs ont souvent inspiré les artistes, peintres, poètes, sculpteurs et décorateurs. La culture des fleurs est la floriculture, une branche de l'horticulture.
La plupart des fleurs sont hermaphrodites, c'est-à-dire qu'elles ont à la fois des organes reproducteurs mâles et femelles : elles ont un pistil et des étamines. Les étamines sont la partie mâle (qui libère du pollen), et le pistil la partie femelle (qui reçoit le pollen). Certaines plantes comme le pistachier ou le kiwi ont des fleurs qui ne sont pas hermaphrodites : elles sont soit mâles, soit femelles, les scientifiques parlent de fleurs gonochoriques. D'autres plantes comme l'avocatier ont des fleurs qui sont successivement mâles et femelles, on parle alors d'hermaphrodisme successif.
La fleur hermaphrodite est constituée de pièces florales insérées sur un réceptacle floral. Lorsque la fleur est complète, elle comprend quatre verticilles de pièces florales. De l'extérieur vers l'intérieur, on rencontre :
le calice, formé par l'ensemble des sépales ;
la corolle, formée par l'ensemble des pétales ;
l'androcée, c'est-à-dire l'ensemble des étamines (partie mâle), qui produit le pollen ;
le gynécée ou pistil, formé par l'ensemble des carpelles (partie femelle).
Calice et corolle forment le périanthe, enveloppe stérile, qui joue un rôle protecteur pour les pièces fertiles, et attractif pour les animaux pollinisateurs.
Ce plan théorique de la fleur, que l'on trouve typiquement chez le bouton d'or (Renonculacées), est sujet à de nombreuses variations. On rencontre par exemple des fleurs sans pétales, dites « apétales ». Une fleur mixte est une fleur qui possède à la fois étamines et pistil.
« La fleur double est celle dont quelqu'une des parties est multipliée au-delà de son nombre naturel, mais sans que cette multiplication nuise à la fécondation. Les fleurs se doublent rarement par le calice, presque jamais par les étamines. Leur multiplication la plus commune se fait par la corolle. Les exemples les plus fréquents sont dans les fleurs polypétales, comme œillets, anémones, renoncules ; les fleurs monopétales doublent moins communément. Cependant on voit assez souvent des campanules, des primevères auricules, et surtout des jacinthes à fleur double. Ce mot de fleur double ne marque pas dans le nombre des pétales une simple duplication, mais une multiplication quelconque. Soit que le nombre des pétales devienne double, triple, quadruple, etc., tant qu'ils ne multiplient pas au point d'étouffer la fructification, la fleur garde toujours le nom de fleur double ; mais, lorsque les pétales trop multipliés font disparaître les étamines et avorter le germe, alors la fleur perd le nom de fleur double et prend celui de fleur pleine. »
Arisaema triphyllum (Linnaeus, 1753) - jack-in-the-pulpit in Ohio, USA.
Plants are multicellular, photosynthetic eucaryotes. The oldest known land plant body fossils are Silurian in age. Fossil root traces of land plants are known back in the Ordovician. The Devonian was the key time interval during which land plants flourished and Earth experienced its first “greening” of the land. The earliest land plants were small and simple and probably remained close to bodies of water. By the Late Devonian, land plants had evolved large, tree-sized bodies and the first-ever forests appeared.
The most conspicuous group of living plants is the angiosperms, the flowering plants. They first unambiguously appeared in the fossil record during the Cretaceous. They quickly dominated Earth's terrestrial ecosystems, and have dominated ever since. This domination was due to the evolutionary success of flowers, which are structures that greatly aid angiosperm reproduction.
The jack-in-the-pulpit is a moderately small angiosperm native to eastern America and eastern Canada.

THE AGE OF FLOWERING PLANTS
ANGIOSPERM means "seed borne in vessel," while GYMNOSPERM means "naked seed," a reference to the lack of protective structure enveloping the seed. One reason that flowering plants were able to diversify so dramatically and spread during the Cretaceous and Cenozoic, or modern, the era was the evolution of new structures and tissues such as the carpel, a womb-like vessel that encloses angiosperm seeds and endosperm, a placenta-like tissue that nourishes the young plant as it develop within the seed, Today, angiosperm dominate terrestrial life on the planet. At an estimated 422,000 species, they compose by far the largest group of plants. They grow in greater range of environments, exhibits a wider range of growth habits, and display more variation in form than any living group of plants. In size, angiosperm range from tiny duckweed to eucaplytuses more than 330 ft (100 m) tall. The explosion of angiosperm diversity has gone hand in hand with the proliferation of insect, birds, and other animals that pollinate their flowers, disperse their fruits and seeds, and eat their leaves.

Lathyrus latifolius Linnaeus, 1753 - perennial pea in Ohio, USA. (18 June 2016)
Plants are multicellular, photosynthesizing eucaryotes. Most species occupy terrestrial environments, but they also occur in freshwater and saltwater aquatic environments. The oldest known land plants in the fossil record are Ordovician to Silurian. Land plant body fossils are known in Silurian sedimentary rocks - they are small and simple plants (e.g., Cooksonia). Fossil root traces in paleosol horizons are known in the Ordovician. During the Devonian, the first trees and forests appeared. Earth's initial forestation event occurred during the Middle to Late Paleozoic. Earth's continents have been partly to mostly covered with forests ever since the Late Devonian. Occasional mass extinction events temporarily removed much of Earth's plant ecosystems - this occurred at the Permian-Triassic boundary (251 million years ago) and the Cretaceous-Tertiary boundary (65 million years ago).
The most conspicuous group of living plants is the angiosperms, the flowering plants. They first unambiguously appeared in the fossil record during the Cretaceous. They quickly dominated Earth's terrestrial ecosystems, and have dominated ever since. This domination was due to the evolutionary success of flowers, which are structures that greatly aid angiosperm reproduction.
The perennial pea is an angiosperm that is native to Europe but now occurs in other parts of the Old World, plus the New World. Flowers are zygomorphic (= bilaterally symmetrical, but not radial) and pale pink to intensely pink-colored.

En biologie, chez les plantes à fleurs (angiospermes), la fleur constitue l'organe de la reproduction sexuée et l'ensemble des « enveloppes » qui l'entourent. Après la pollinisation, la fleur est fécondée et se transforme en fruit contenant les graines. Les fleurs peuvent être solitaires, mais elles sont le plus souvent regroupées en inflorescences.
Très tôt, les fleurs ont attiré l’attention de l’homme, qui les utilise et les cultive pour la parure (couronne de fleurs), pour l’ornementation intérieure (fleurs coupées, bouquets, ikebana) et extérieure (jardins, plates-bandes, etc.) ainsi que pour leurs odeurs et pigments. Les fleurs ont souvent inspiré les artistes, peintres, poètes, sculpteurs et décorateurs. La culture des fleurs est la floriculture, une branche de l'horticulture.
La plupart des fleurs sont hermaphrodites, c'est-à-dire qu'elles ont à la fois des organes reproducteurs mâles et femelles : elles ont un pistil et des étamines. Les étamines sont la partie mâle (qui libère du pollen), et le pistil la partie femelle (qui reçoit le pollen). Certaines plantes comme le pistachier ou le kiwi ont des fleurs qui ne sont pas hermaphrodites : elles sont soit mâles, soit femelles, les scientifiques parlent de fleurs gonochoriques. D'autres plantes comme l'avocatier ont des fleurs qui sont successivement mâles et femelles, on parle alors d'hermaphrodisme successif.
La fleur hermaphrodite est constituée de pièces florales insérées sur un réceptacle floral. Lorsque la fleur est complète, elle comprend quatre verticilles de pièces florales. De l'extérieur vers l'intérieur, on rencontre :
le calice, formé par l'ensemble des sépales ;
la corolle, formée par l'ensemble des pétales ;
l'androcée, c'est-à-dire l'ensemble des étamines (partie mâle), qui produit le pollen ;
le gynécée ou pistil, formé par l'ensemble des carpelles (partie femelle).
Calice et corolle forment le périanthe, enveloppe stérile, qui joue un rôle protecteur pour les pièces fertiles, et attractif pour les animaux pollinisateurs.
Ce plan théorique de la fleur, que l'on trouve typiquement chez le bouton d'or (Renonculacées), est sujet à de nombreuses variations. On rencontre par exemple des fleurs sans pétales, dites « apétales ». Une fleur mixte est une fleur qui possède à la fois étamines et pistil.
« La fleur double est celle dont quelqu'une des parties est multipliée au-delà de son nombre naturel, mais sans que cette multiplication nuise à la fécondation. Les fleurs se doublent rarement par le calice, presque jamais par les étamines. Leur multiplication la plus commune se fait par la corolle. Les exemples les plus fréquents sont dans les fleurs polypétales, comme œillets, anémones, renoncules ; les fleurs monopétales doublent moins communément. Cependant on voit assez souvent des campanules, des primevères auricules, et surtout des jacinthes à fleur double. Ce mot de fleur double ne marque pas dans le nombre des pétales une simple duplication, mais une multiplication quelconque. Soit que le nombre des pétales devienne double, triple, quadruple, etc., tant qu'ils ne multiplient pas au point d'étouffer la fructification, la fleur garde toujours le nom de fleur double ; mais, lorsque les pétales trop multipliés font disparaître les étamines et avorter le germe, alors la fleur perd le nom de fleur double et prend celui de fleur pleine. »
