Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If cell A with OP = 5 and TP = 4 is surrounded by cells with OP = 3 and TP = 1, what will be the direction of water?
A
From cell A to other cells
B
From other cells to cell A
C
Water will not move
D
Water will move up
Explanation: 

Detailed explanation-1: -Hence, the correct answer is ‘From cell A to other cells’.

Detailed explanation-2: -Answer is 4) OP and DPD decrease and TP increase. When water enters into cell then the cell increases in size due to entry of water therefore TP (Turgor pressure) increases but due to decrease in concentration of the solution inside the cell due to entry of water the OP (osmotic pressure) decreases.

Detailed explanation-3: -Since in hypotonic solution osmotic pressure is less water will flow into the cell and cell will swell.

Detailed explanation-4: -Plant cells swell up when kept in hypotonic solution because plant cells absorb large amounts of water in hypotonic solution such that the vacuole is completely filled with water and the cytoplasm presses against the cell wall.

Detailed explanation-5: -Water moves by osmosis, which is a type of diffusion, into and out of the cell. Through the cell membrane, water molecules flow through osmosis from a lower solute concentration to a higher solute concentration.
