Question

Choose the false statement.

• A. Spores of class Rhodophyceae do not have flagella
• B. Spores of Phaeophyceae - are round in shape
• C. Spores of class Chlorophyceae have many flagella
• D. Spores of class Phaeophyceae have laterally attached flagella

Answer 1

The correct option is B Spores of Phaeophyceae - are round in shape

Algae reproduce asexually by producing tough structures called spores. Each spore is capable of growing into a new individual. These spores are different in different classes of algae.

In Chlorophyceae, the spores produced have one or more flagella. In Phaeophyceae, the spores are pear-shaped and have two unequal flagella. These flagella are laterally attached. The spores of both Chlorophyceae and Phaeophyceae have flagella and are motile spores. Motile spores are also called zoospores. The spores of class Rhodophyceae are round and non-motile.
