Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /). [5] [6] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit.
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
An aggregate fruit is also called an aggregation, or etaerio; it develops from a single flower that presents numerous simple pistils. [17] Each pistil contains one carpel; together, they form a fruitlet. The ultimate (fruiting) development of the aggregation of pistils is called an aggregate fruit, etaerio fruit, or simply an etaerio.
Flowering plants, also known as angiosperms, spread during this period, although they did not become predominant until near the end of the period (Campanian age). [18] Their evolution was aided by the appearance of bees; in fact angiosperms and insects are a good example of coevolution.
Flower of Liriodendron tulipifera, a Mesangiosperm. Mesangiospermae is a clade that contains the majority of flowering plants (angiosperms). Mesangiosperms are therefore known as the core angiosperms, in contrast to the three orders of earlier-diverging species known as the basal angiosperms: Nymphaeales (including water lilies), Austrobaileyales (including star anise), and Amborellales.
Following the pollination of a flower, fertilization, and finally the development of a seed and fruit, a mechanism is typically used to disperse the fruit away from the plant. [97] In Angiosperms (flowering plants) seeds are dispersed away from the plant so as to not force competition between the mother and the daughter plants, [ 98 ] as well ...
The fig fruit develops as a hollow, fleshy structure called the syconium that is lined internally with numerous unisexual flowers. The tiny flowers bloom inside this cup-like structure. Although commonly called a fruit, the syconium is botanically an infructescence, a type of multiple fruit. The small fig flowers and later small single-seeded ...
Phoenix dactylifera, commonly known as the date palm, [2] is a flowering-plant species in the palm family Arecaceae, cultivated for its edible sweet fruit called dates.The species is widely cultivated across northern Africa, the Middle East, the Horn of Africa, Australia, South Asia, and California.
