expansion and success What will be an ideal response?
Adaptations include the following:1.
Closed carpels and double fertilization for increased likelihood of reproductive success
2. Interdependence with animals, particularly insects, for more efficient pollination
3. Vessel elements for more efficient water conduction
4. Sieve tube elements for more efficient carbohydrate conduction
5. Broad leaves for more efficient absorption of light
6. Stems and roots modified for food or water storage
7. Adaptability of the sporophyte generation to new environments
