• In Algae a nucleus is present, and multiple chromosomes are observed. The chlorophyll and other pigments occur in its chloroplasts, which contains membranes known as thylakoid.
• Most algae live on photosynthesis. Some forms, however, obtain energy from chemical reactions.
• Reproduction in algae occurs in both asexual and sexual forms.
