Answer 2

Answer:

The outer covering of a typical plant cell is D) Cell wall externally, Plasma membrane internally.

Explanation:

• A plant cell is externally covered by the cell wall and is followed by a layer of the plasma membrane or cell membrane.
• The plant cell wall is made up of layers and is composed of cellulose, pectin, lignin, hemicellulose, and soluble protein.
• Its functions include- protection and providing structural framework and support to the plant growth.
• The cell membrane which follows the cell wall layer is a semi-permeable membrane that has a major role in the regulation of components that enter and exit the cell.
