Answer 1

Answer:

6. Why is Plasma Membrane a selectively permeable membrane?

The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. If plasma membrane ruptures or breaks down then molecules of some substances will freely move in and out of the cells.

7. What is the function of chromosome?

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 7 likely contains 900 to 1,000 genes that provide instructions for making proteins.

8. Name the cleansing organelle in the cell.

Ribosomes are known as the cleansing organelle in the cell

9. How does amoeba consume food?

Amoeba envelops its food through the process of endocytosis or phagocytosis, where pseudopodia is created by flexibility of the plasma membrane. ... Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm.
