Question

Which characteristic is common to both unicellular and multicellular algae?

A) presence of a flagella for locomation
B) presence of chlorophyll a for carrying out photosynthesis
C) cell walls made of cellulose

Answer 1

The correct answer is option B.

Step-by-step explanation:

Algae refer to the photosynthetic, eukaryotic species, which do not produce multicellular sex organs. They can be unicellular or can be large multicellular species. Algae can develop in fresh or salt waters, or on the surface of the moist rocks or soil.

The multicellular algae give rise to unique tissues, however, they are devoid of true leaves, stems, or roots of the more composite higher plants. However, whether an alga is unicellular or multicellular, one can always witness the existence of chlorophyll a for conducting the process of photosynthesis.

Answer 2

The characteristic is common to both unicellular and multi cellular algae is the presence of chlorophyll a for carrying out photosynthesis. The correct answer is B.
