Question

Presence of aplanospores in Ulothrix is an example of

• A. Dead cell
• B. Vestigial cell
• C. Accessory cell
• D. Beginning of division of labour

Answer 1

The correct option is D Beginning of division of labour

Ulothrix is a species of filamentous green algae that reproduces vegetatively by fragmentation. The asexual reproduction takes place with the help of aplanospores which are non-motile resting spores and zoospores. The biflagellate gametes are responsible for its sexual reproduction. The presence of aplanospores is therefore an example of division of labour.

Therefore, the correct answer is option D.
