Question

Carbohydrates present in the plasmalemma are in the form of-
A. Glycoprotein and glycolipids
B. Cellulose
C. Hemicellulose
D. Starch

Answer 1

Plasmalemma is a less common term for the cell membrane, a thin layer that encloses a cell’s cytoplasm, which is the substance present between the membrane and the nucleus. It allows beneficial things to pass through while blocking the harmful ones. It is also called the plasma membrane.

Complete answer:
The cell is the basic structural and functional unit of all living organisms. It is a microscopic structure consisting of a nucleus surrounded by the cytoplasm and enclosed by a membrane called the plasmalemma. In general, a membrane is a thin barrier/covering. In the context of biology, plasma is another word used for cytoplasm.
The membrane is a double layer made up of lipid molecules and large protein molecules. Lipids and proteins are the basic building blocks of all living cells. They move fluidly in the plasmalemma and function like a system of gates, giving the membrane its ability to allow molecules to pass through it. For this reason, the membrane is described as a semipermeable.

Thus the correct option is A. 'Glycolipids and glycoproteins'

Note:
The makeup of the plasmalemma includes three crucial components as phospholipids, cholesterol, and proteins. The phospholipids attract and repel the water. The layer created by these opposing forces is known as phospholipid bilayer. It’s responsible for creating the spaces within the membrane and making it a good barrier for many things. Proteins help with transporting cell components across this barrier and cholesterol also helps with this regulation.
