Question

8. How is the cell wall different from the cell membrane?
O The cell wall is only in plant cells
The cell wall is in animal and plant cells
The cell membrane provides protection
All cells only have a cell membrane

Answer 1

A- the cell wall is only in plant cells.

Cell walls made of cellulose are only found around plant cells and a few other organisms. Cows and other herbivores have special bacteria in their stomachs to digest the cellulose polymers. While cell walls protect the cells, they also allow plants to grow to great heights.

Hope this helps and have a great day! (Also brainliest would be appreciated but you don’t have to:) )

Answer 2

Hint: The cell wall is the outer layer of the cell. It covers outside the cell membrane. It consists of cellulose, carbohydrates, hemicellulose, lignin and pectin. Cell membrane is present in plant cells. It is also known as plasma membrane.
It is semi permeable in nature. Its composition includes proteins and lipids.

Complete answer:
Cell is a basic building block of life. It is the fundamental unit of an organism.
The function of cell wall is:
- It prevents the cell from outer damage and maintains and regulates the cell growth.
- It provides strength and shape to the cell.
- It stores carbohydrates.

The function of cell membrane is
- Maintains the integrity of the inner cell.
- Maintains the shape of the cell.
- Maintains the cell growth and balance.
- It has a major role in communication.
- It only allows selective substances to enter the cell.
