27
Q

Angiosperm Reproduction Phylum Anthophyta (flower plant)

What are some angiosperm advantages?

A
  • shorter generation times(more rapid natural selection
  • More efficient pollination (flowers/pollinators (doesn’t have to rely on something like wind) because of this there is an increase in cross pollination.
  • better seed dispersal (fruit)
  • more efficient vascular tissue
  • (covered seeds)
