NEET BIOLOGY

Detailed explanation-1: -Multicellular examples of algae include the giant kelp and brown algae. Unicellular examples include diatoms, Euglenophyta and Dinoflagellates. Most algae require a moist or watery environment; hence, they are ubiquitous near or inside water bodies.

Detailed explanation-2: -Multicellular Algae True multicellular forms are characterized by having separate cells, each with its own nucleus, plasma membrane, and cell wall. Streptophytes and many multicellular chlorophyte algae are organized in this manner.

Detailed explanation-3: -General Morphology. Similar to red algae, green algae can be unicellular or multicellular. Many unicellular species form colonies.

Detailed explanation-4: -Chlorella is the unicellular algae.

Detailed explanation-5: -Algae are eukaryotic organisms and contain three types of double-membrane-bound organelles: the nucleus, the chloroplast, and the mitochondrion. In most algal cells, there is only a single nucleus, although some cells are multinucleate.
