Question

what are the different cell and plant membrane and their functions?

Answer 1

The cell membrane functions are as below:

1. They help to keep toxic substances away and out from the cell.
2. The cell membrane function in transport of specific molecules such as ions, nutrients, wastes, and metabolic products between organelles as well as between the cell and the outside environment as they possess receptors and channels.
3. The cell membrane functions to separate the organelles from each other as well as the metabolic processes that are conducted within organelles.

The functions of plasma membrane are as below:

1. Plasma membrane function in transportation of specific molecules in and out of the cell.
2. Form structural barrier between the internal contents and external enviroment.
3. Plasma membranes in plants contain receptor proteins that help to receive signals from the environment as well as from plant hormones that direct plant growth and division.
4. In plants, the plasma membrane plays an important role in cellulose synthesis as it is the site for cellulose synthesis.
