Show Answer
Answer:
Correct Answer: D
Solution:
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.
