Small surface area of cactus needles helps the plant in
Reducing water loss
Sunlight absorption
Insects attraction
Birds attraction
Absorption of water by the plant cells by surface attraction is called:
(a) Diffusion (b) Osmosis
(c) Imbibition (d) Endosmosis
Assertion (A): In Cactus, leaves are reduced to small spines with less surface area. Reason (R): Spines helps in preventing the cactus from losing water through evaporation.
