Question on: JAMB Biology - 2014
Seed plants are the most dominant vegetation on land because of
A
their motile gamates
B
their ability to photosynthesize
C
efficient seed dispersal
D
availability of water
Ask EduPadi AI for a detailed answer
Correct Option: C
The dominance of seed plants on land is primarily attributed to efficient seed dispersal. Here's why:
- Efficient seed dispersal: Seeds enable plants to colonize new areas, escape competition with the parent plant, and survive harsh conditions. Various dispersal mechanisms (wind, water, animals) increase the chances of successful reproduction and survival.
- Other options:
- A: Seed plants do not have motile gametes.
- B: All plants photosynthesize, not just seed plants.
- D: While water is essential for all plants, it is not the primary reason for the dominance of seed plants.
