• B. Spirogyra does not produce zoospores.
• C. All algae are filamentous.
• D. Most algae are photosynthetic.

Answer 1

Answer: (C)

Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be classified according to their pigments as red algae, brown algae and green algae. No zoospores or cells with flagella are produced by Spirogyra. All algae are not filamentous. Thus, the correct answer is option C.
