(A) ENDOCYTOSIS (B) DIFFUSION (C
(D)PLASMOLYSIS
(E) GENES
(G) GENES
2.HOW DOES OXYGEN AND CARBON DIOXIDE
3.DISTINGUISH BETWEEN ISOTONIC, HYPOTON
Answers
Answer:
1. Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
2.Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.
3. plasmolysis is the process in which cells lose water in a hypertonic solution
Explanation:
1.(A) Endocytosis is the process of actively transporting molecules into cell by engulfing it with its membrane.
(B) Diffusion is the net passive movement of particles from a region in which they are in higher concentration to region of lower concentration.
(C)Plasmolysis is the concentration of protoplast of a plant cell as a result of loss of water from cell .
