BIOL 1050 Study Guide - Quiz Guide: Sepal, Megaspore, Double Fertilization
Document Summary
Classified in a single phylum known as anthophyta. Have to look at the key adaptions of flowers and fruits and the roles these structures play in the angiosperm life cycle. The flower is an angiosperm structure specialized for sexual reproduction. Flower: in an angiosperm, a specialized shoot with up to four sets of modified leaves, bearing structures that function in sexual reproduction. Many angiosperm species use insects or other animals to transfer pollen from one flower to the sex organs on another flower. Angiosperms are also wind pollinated (particularly species that occur in dense populations like grasses) Wind pollinated plants are responsible for seasonal allergies when our immune systems react to the proteins present on the outer surface of the pollen grains. Starting at the base of the flower there are the sepals, which are usually green and enclose the flower before it opens.
