Topic #4: Angiosperm Adaptations REQUIREMENTS: Powerpoint presentations. Objectives 1. What is a pollination vector? Give examples. Discuss the relationship of vectors to floral evolution.


The endosperm in angiosperm seeds is a result of a rather unusual fertilization. The egg produced by the female is 1n, but it is surrounded by some other tissue (also 1n).


The derivation of angiosperm means seed in a box or case and is from the Greek words angio meaning box, case, or vessel and sperm meaning seed.

However, angiosperm ovules unlike gymnosperm ovules, are completely isolated from the outside world by sporophytic tissue. Another difference between angiosperm and gymnosperm ovules is that those of angiosperms are attached to the placenta by a stalk called a funiculus. The ...
