animation of osmosis by the roots

It is a physical process in which the solvent (water) moves from the region of its higher concentration to the region of its lower concentration across a semi-permeable membrane. This is to say that water moves from a dilute to a concentrated solution. Water is absorbed into the root cell..

Solutions..

Roots absorb water from the soil by osmosis or diffusion as the water is in higher concentration in the soil than in the roots. The absorption may take place into the intercellular spaces of the root cells or the root hairs. Root hairs ..

Summary - Excretion is the elimination of waste products from the body. The non - volatile products are mainly excreted in the urine. The urinary system consists of those organs which form, store and void urine. The nitrogenous wastes are mainly produced by catabolism of proteins. Animals..

In unicellular organisms a single cell carries out all the life processes as the cell itself is the organism. In advanced forms like the few-celled algae, protozoa, sponges, etc., the size of the organism ensures that all the cells are not very far from each other. The uptake of materials from the ..

Passive absorption is by osmosis. Passive absorption takes place along the concentration gradient - when the concentration of cell sap is higher than that of soil water. Water is absorbed when transpiration rate is high or soil is dry. Due to high transpiration rate, water deficit is crea..

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..

Question: The ascent of sap in plants takes place due to __________. 1. root pressure 2. transpiration pull 3. both a and b 4. osmosis Answer: ..

excretion osmoregulation The water content in the organism has to be regulated as there is a constant inflow of excess water. This is because the cell membrane surrounding the animal is semipermeable and as the protoplasm contains a higher concentration of salts than the water outs..

Summary - Cell is the structural and functional unit of the organism. Water is the principal constituent of plants and is essential for the maintenance of life, growth and development. Plants absorb water from the soil through their roots, transport it to other parts of the plant through ..
