Which of the following statements are true/false?
I. The positive hydrostatic pressure is called turgor pressure.
II. Wall pressure exerts to prevent the increase of protoplasm size.
III. Diffusion is more rapid in liquids than in gases.
IV. Diffusion of water through a semi-permeable membrane is called imbibition.
V. Osmosis is movement of substance, which takes place along a diffusion gradient

View answer and explanation
Correct option: A
I and II are true, while III, IV and V are false
Option A (I and II are true, while III, IV and V are false) is correct because turgor pressure is positive hydrostatic pressure, wall pressure prevents protoplasm increase, diffusion is faster in gases, water movement is osmosis, and osmosis follows water potential gradient.
