Current Question (ID: 12223)

Question:

In pteridophytes, gametophyte that develops in the homosporous species is usually

Options:

1. Monoecious and has events, precursor to the seed habit.
2. Dioecious and does not lead to seed habit.
3. Monoecious and does not lead to seed habit.
4. Dioecious and has events, precursor to the seed habit.

Solution:

Homosporous pteridophytes produce a single type of spore that develops into a bisexual (monoecious) gametophyte. This gametophyte produces both male and female gametes, which fuse to form a zygote and initiate the sporophyte generation. However, unlike seed plants, pteridophytes do not have a seed habit, and the sporophyte is dependent on the gametophyte for nutrition.
