Vitamins are biological products of plants. They also form a valuable part for the normal growth and development of organisms. Vitamins are mostly synthesised by plants and are stored in their various organs. They control important biochemical reaction in growth plants and anima..

Tonicity of Solutions - Cell walls in living organisms are seldom perfectly semipermeable. Usually they permit passage to some of the simpler substances and then these substances fail to register an osmotic pressure contribution on the cell walls. The reduced osmotic pressure of a solution operatin..

Primary phloem is the phloem that is formed during normal growth in the plant body. It is a derivative of primary meristem. It is found in both monocots and dicots. The primary phloem is further composed of protophloem and metaphloem. The sieve tubes and the companion cells, wh..

Mycorrhizae is a type of fungus living in association with plant roots. Hyphae of such fungi are found in between cortical cells of roots and protrude outside the roots also. The Mycorrhizae lives in close association with roots without disturbing their normal physiology. These hyphae ..
