Question

Choose the wrong statement.

• A. During fragmentation the plant thallus breaks into many fragments and each fragment grows into a new offspring.
• B. Generally filamentous algae undergo fragmentation.
• C. Fragmentation is a type of vegetative reproduction.
• D. Spore formation is a type of vegetative reproduction.

Answer 1

The correct option is D Spore formation is a type of vegetative reproduction.

Fragmentation is a type of asexual reproduction. During fragmentation the organism breaks into fragments and each fragment grows into a new organism. Filamentous green, brown and red algae undergo fragmentation.

In plants, any type of asexual reproduction that does not involve spores is also knows as vegetative reproduction. So we can say that fragmentation is a type of vegetative reproduction while spore formation is not. Spore formation is a type of asexual reproduction.
