Question

Which of the following important features are found in blue green algae?

• A. Abundant secretion of pectin
• B. Presence of phycocyanin C as dominant pigment
• C. Plastids
• D. All of the above

Answer 1

The correct option is D All of the above

The prokaryotic blue-green can be characterized by their cell walls and their pigments. As they are bacteria, the cell walls of blue-green algae are composed of several layers of mucoprotein and other polysaccharides including lipopolysaccharides. Cellulose, which is found in the cells of flowering plants, is mostly absent. They secrete pectin abundantly. The pigments in blue-green algae are chlorophyll a, carotenoids, phycocyanin (blue), and phycoerythrin.

Thus, the correct answer is option (D).
