By which of the following methods do red algae reproduce?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Fragmentation.
- Red algae can reproduce by fragmentation, but they also reproduce through other methods, including spore formation. This is an asexual method where a piece or fragment of the algae breaks off and grows into a new individual. It is a common form of vegetative reproduction.
- Red algae can also reproduce sexually through the formation of spores. The gametes (male and female) fuse to form a zygote, which develops into a new organism. In sexual reproduction, red algae form structures called carposporophytes, which produce carpospores that grow into new individuals.
