Question

Identify the character which is absent in Fucus?

• A. Nonflagellated male gametes
• B. Holdfast
• C. Heterogametes
• D. Oogamy

Answer 1

The correct option is A Nonflagellated male gametes

Fucus is a perennial algae, some of which have a life span of up to four years. They feature bladder like floats, disk-shaped holdfasts for clinging to rocks and mucilage-covered blades that resist desiccation and temperature changes. They are heterogametes and oogamy occurs in them. Sperm are attracted through the anterior flagella and only one sperm and one egg holds the haploid condition.

So, option A is the correct option.
