Question

Spores no longer disperse in angiosperms. What structures are capable of dispersing for reproductive purposes instead?

Answer 1

Spores are no longer disperse in angiosperms because during evolution the mechanisms had changed. And, in angiosperms the fruit is responsible for dispersing seeds.

• In angiosperms the seeds are covered and produce flowers which have male/female or both reproductive structures. Plant doesnot have mobility and that is the the reason for such having such mechanisms.
• The agents that commonly assist seed dispersal are wind, water and animals.
• The ovules will develop into seeds and the ovary will develop into fruit after fertilization.
• Zygote(2n) and endosperm(3n) are the end product of double fertization in angiosperms.
