Answer 1

Answer:

In a plant cell –

A) the cytoplasm lining if the cell wall acts as the semi permeable membrane.

mark me as brainliest plz.....

Answer 2

In plant cells: the cytoplasm that lines the cell wall acts as a semipermeable membrane.

Option A is correct.

• This is the second lining after the rigid cell wall which is made up of lipids and proteins.
• The cytoplasm is a thick aqueous solution in which the organelles are found.
• Plant cytoplasm is a semipermeable membrane that is they allow the entry of only selected molecules in and out of the cytoplasm of the cell.

Option B is incorrect.

• The cytoplasm is found inside of the cell wall made up of protein and fats.
• The cytoplasm is a matrix within which the plant's organelle is suspended.
• Salts, nutrients, minerals and enzymes are dissolved in the cytoplasm.

Option C is incorrect.

• Cell walls are rigid protecting layers along the plant's cells. Cell walls are arranged in layers containing cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein.
• The cell wall is to provide structural strength and support to the plant cell, and also provides a permeable surface for molecules to pass in and out of the cell.

Option D is incorrect.

• Cell sap is the liquid present inside the large central vacuole of a plant cell.
• It acts as a storage of material and it also provides mechanical support.
