In which of the following organisms does each cell combine the function of nutrition, reproduction and growth?
Answer Details
The organism in which each cell combines the function of nutrition, reproduction, and growth is Spirogyra. Spirogyra is a type of filamentous green algae that consists of a long chain of cells. Each cell of Spirogyra has a nucleus, chloroplasts, and a large central vacuole. The chloroplasts are responsible for photosynthesis and the production of food for the cell. The nucleus controls the cell's activities, including growth and reproduction. Spirogyra reproduces asexually by the process of fragmentation, where a part of the filament breaks off and forms a new filament. It also reproduces sexually by the process of conjugation, where two filaments come together and exchange genetic material. So, in summary, Spirogyra is the organism in which each cell combines the function of nutrition, reproduction, and growth.
