terrestrial plant can absorb

Acidic water is dangerous to plants. Sulphuric and nitric acid rain washes nutrients out of the soil, damages the bark and leaves of trees and harms the fine root hairs of many plants which are needed to absorb water. Leaf pigments are decolorized because acid affects..

After nitrates have been absorbed by the plant, they are reduced to ammonia with the help of two enzymes nitrate reductase and nitrite reducta..

Nitrogen is one of the important elements found in living organisms. Supply of nitrogen from the atmosphere is maintained. Nitrogen is an essential constituent of amino acids and hence the proteins cannot be absorbed by the plants directly from the atmosphere though it contains ..

Water is absorbed due to activities going on in roots. Absorption of water occurs with the help of energy in the form of ATP, which is released due to metabolic activities of root cells such as respiration. Absorption takes place against concentration gradient - even when the concen..

Absorption of Water by Plants - Plants absorb water through the entire surface - roots, stems and leaves. However, mainly the water is absorbed by roots. The area of young roots where most absorption takes place is the root hair zone. The root hairs are delic..

The epidermis usually forms projections known as epidermal hairs. In the root, the epidermal hairs are unicellular and are called as root hairs. The root hairs penetrate between the soil particles to absorb water. In the stem and the leaf, the epidermal hairs are multicellular and a..

Introduction - The study of world of life is as old as man itself. All living organisms are made up of a few elements which are repeated in each of them. The basic unit of life - cell, is a structural and functional entity of life. Of all the environmental factors that affect plant life, ..

Saprotrophs are decomposers and liberate energy for their own use by breaking down complex organic matter from the dead bodies of other organisms. At the same time this process releases vital chemical elements into the soil which are absorbed by autotrophs. Thus saprotrophs aid the re..

i) Considerable amount of phosphorus from the soil rock is washed into the sea by rains and floods (an estimated amount of 2 million tonnes of phosphotic rock is lost to sea) where sea weeds take up phosphorus and is then passed onto fishes and sea birds. ii) Terrestrial plants ..

Soil is the major source of water for plants. The plants absorb water through root hairs from the soil. The total water content present in the soil is called holard. Out of this, the water which can be absorbed by plants is chresard and remain..
