13.2 :-What is the function of the above mentioned pigment?
13.3 :-What did Aarti observe when she poured sugar solution over the slide?
13.4:- Deline plasmolysis.

Answer 1

Answer:

1 ) Chlorophyll is a pigment found in the thylakoid membranes of the chloroplasts in the leaves. This is why plants are green. The simple answer is that plants are green because they have green chloroplasts (organelles that carry out photosynthesis).

4 ) Plasmolysis is the process in which cells lose water in a hypertonic solution. ... A cell will begin to decline in turgor pressure only when there is no air spaces surrounding it and ...
