Read the passage and answer the following question:
In order to prevent changes in volume due to osmosis, unfertilized frog oocytes were bathed in Frog Ringer's solution. The Frog Ringer's solution was supplemented with radiolabeled amino acids. A sample of oocytes was taken every 30 minutes and assayed for radioactivity. At time 1, the oocytes were fertilized. Samples were taken at five-minute intervals after fertilization and assayed for radioactivity. The results are presented in the graph.
Based on the results of the experiment, the process most likely occurring after fertilization is

Compare the statement A and B.
Statement A : To counteract the increase in turgor pressure in plant cells, the cell wall produces an equal and opposite pressure, ie, wall pressure.
Statement B : When plant cells undergo endosmosis, they swell but do not burst.
Select the correct description.

Read the passage and answer the following question.
Wet mounts of three living samples of elodea cells are prepared for viewing under the light microscope. Each slide is mounted with a different solution and viewed after 5 minutes.
Sample A - Elodea + 5 drops of 10% NaCl
Sample B - Elodea + 5 drops of isotonic saline
Sample C - Elodea + 5 drops of distilled water
What would happen to the cells in sample A?

Cell A and cell B are adjacent plant cells. In cell A, $${ \psi  }_{ S }=-20$$ bars and $${ \psi  }_{ P }=8$$ bars. In cell 'B', $${ \psi  }_{ S }=-12$$ bars and $${ \psi  }_{ P }=2$$. Then,
