angiosperm – מילון אנגלי-אנגלי
angiosperm
n.
plant whose seeds are contained in an ovary or fruit
Flowering plant
The
flowering plants (
angiosperms), also known as
Angiospermae or
Magnoliophyta, are the most diverse group of
land plants, with about 350,000 species. Like
gymnosperms, angiosperms are
seed-producing plants; they are distinguished from gymnosperms by
characteristics including
flowers,
endosperm within the seeds, and the production of
fruits that contain the seeds. Etymologically, means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the
Greek composite word (angeion-, "case" or "casing", and sperma, "seed") meaning "enclosed seeds", after the enclosed condition of the seeds.

About
Angiosperm
The most recently evolved and the largest group of plants whose reproductive organs are in their flowers (flowering plants). A superclass in the sperm plants (Spermatophyta) division belonging to the vascular plants (Tracheophyta) phylum of the plant kingdom. They are divided into two subclasses: Dicots (Magnoliopsida such as magnolia, dandelion, roses, violet) and Monocots (Liliopsida such as lilly, iris, orchid, grasses). Their ovules are enclosed in the carpel and pollen travels through the pollen tube to reach it. Angiosperms evolved in the Cretaceous era together with the Mammals.
