Question

How do bacteria excrete waste?

Answer 1

Excretion in bacteria:

1. Bacteria excrete out the metabolic waste via passive diffusion.
2. Diffusion involves the process of movement of particles from a site of higher concentration to a site of lower concentration.
3. The waste material moves out through the cell membrane.
4. The diffusion of waste material can also occur against the concentration gradient with expenditure of energy.
