Which of the following statements are true/false?
(a) The positive hydrostatic pressure is called as turgor pressure.
(b) Wall pressure exerts to prevent the increase of protoplasm size.
(c) Diffusion is more rapid in liquids than in gases.
(d) Diffusion of water through a semi-permeable membrane is called as imbibition.
(e) Osmosis is movement of substances, which takes place along a diffusion gradient.
The correct option is A a and b are true and c, d, and e are false
Turgor pressure is the positive hydrostatic pressure applied by protoplasm on the cell wall when the protoplasm swells due to an increase in volume caused due to endosmosis.
When the protoplasm applies turgor pressure on the wall, the wall applies an equal and opposite wall pressure to the protoplasm.
Diffusion is a slow physical process, which describes the movement of substances along the concentration gradient. It occurs in all three states of matter and its rate does not change with the physical state of the substance.
Imbibition is the physical surface adsorption of solvent onto the matrix or adsorbing surface.
The statement 'e' is wrong because osmosis is the movement of water not substances.
