Answer:
Algae are classified based on the
1. type of chlorophyll and secondary pigments
2. method of food storage
3. composition of cell wall
Explanation:
Algae can be classified on the basis of chlorophyll or other secondary pigments. For example, green algae have chlorophyll a and b. Brown algae possess chlorophyll a, c, carotenoids and xanthophyll pigments. Red algae possess a red pigment called r-phycoerythrin.

one way it can mutate is if it spreads
In a cladogram the tiny indentations along the bottom line is an evolution or change and every organism after the indentation on the bottom line has it and every organism before the indentation does not
