Read the following statements and choose the correct option: 1. Rhodophyceae occur in both well-lighted regions close to the surface of water and also at great depths in oceans where relatively little light penetrates. 2. The red thalli of most of the red algae multicellular 3. The food is stored as mannitol and laminarin. 4. The red algae usually reproduce vegetatively by fragmentation

Step-by-step solution

In Rhodophyceae, they occur in both well-lighted regions close to the surface of water and also at great depths in oceans where relatively little light penetrates. The red thalli of most of the red algae are multicellular. The food is stored as floridean starch which is very similar to amylopectin and glycogen in structure. The red algae usually reproduce vegetatively by fragmentation
