Question

Algae are eukaryotic and autotrophic. They are unicellular or multicellular plant-like organisms. They have a thallus-like structure and lack roots, stem and leaves. Like plant cells and bacterial cells, they have a cell wall. As they are eukaryotic, they also have specialised organelles such as mitochondria and chloroplasts. Algae contain chlorophyll and other coloured pigments. Based on the colour of the pigments, the algae are classified as green algae, brown algae, blue-green algae and red algae. Some algae are motile. Algae show both modes of reproduction, sexual and asexual.
