Green algae have chlorophylls a and b and store starch as a food reserve inside their plastids. The colours of brown algae cover a spectrum from pale beige to yellow-brown to almost black and contain such as chlorophyll c and fucoxanthin. They also lack the plasmodesmata and starch production. Definite tendency is seen among the members of chlorophyceae to migrate towards land and lead life like land plants. Presence of chlorophyll-a, c, fucoxanthin with mannitol and laminarin as reserve food material are the characteristics of. 3. Sexual reproduction is very rare when present it is isogamous type. Unicellular species are more. They are flagellates produced from the parent cells by mitosis. (d) Blue-green algae. They reproduce by all the three means: vegetative, asexual and sexual. Akinetes have been reported from several Chlorophyceae, e.g., Oedogonium, Ulothrix, etc. 1.
