Answer 1

Required Answer:-

The plasma membrane is composed of

• pectin
• chitin
• lipids and proteins ✓
• cellulose

Explanation:-

Plasma membrane is the selectively permeable membrane found in all types of cells maybe outer or Maynot be. They are made up of lipids and proteins which ensures its flexibility.

• Also known as cell membrane or biomembrane.
• It is thin, elastic, living and selectively permeable because it allows solvent and certain selective particles.
• Average composition contains proteins, lipids and carbohydrates$.$
• Most accepted model was fluid mosaic model which was proposed by Singer & Nicolson.
• The carbohydrates attached to proteins are known as glycoproteins and those attached to lipids are known as glycolipids.

Answer 2

Answer:

Required Answer :-

Lipids and Proteins

Explanation :-

Plasma membrane is also known as cell membrane. It work is to protect cell from the unknown environment. It has high amount of Protein and lipids. So, that the membrane may fought diseases as well. It is very thin. They are living and flexible tissue.

Note : Structure in attachment
