2. Cell with certain specific components within it known as (a) Plasma membrane (b) Nucleus (c) Cell wall (d) Organelles
Answers
Answer:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.
Answer:
A
Explanation:
(a) cell wall (b) cell membrane (c) protoplasm (d) cell organelles (e) nucleus (f) chromosomes
The cell wall is a protective outermost layer, which is present surrounding the cell membrane in a plant cell.
The cell membrane is also known as plasma membrane. It is present below the cell wall.
Cytoplasm is a gel-like substance present between the nuclear membrane and plasma membrane. The fluid filled in the nucleus is known as nucleoplasm. Cytoplasm along with the nucleoplasm is known as protoplasm.
Cell organelles have membranous covering in a eukaryotic cell. It lies freely in the cytoplasm.
The nucleus of the cell contains a majority of the cell's genetic material, i.e., chromosomes, which thread like in appearance.
Chromosomes carry the hereditary material from one generation to the other.
So, the correct answer is option A.
