NEET BIOLOGY

Detailed explanation-1: -The orthophosphates, H2PO4-and HPO42-, are the primary forms of phosphorus taken up by plants. When the soil pH is less than 7.0, H2PO4-is the predominate form in the soil. Although less common, certain organic phosphorus forms can also be directly taken up by plants.

Detailed explanation-2: -Plants absorb phosphorus as phosphates, which includes both dihydrogen phosphate and hydrogen phosphate form.

Detailed explanation-3: -Plants absorb nitrogen from the soil in the form of nitrate, nitrite and urea. In aerobic soils where nitrification can occur, nitrate is usually the predominant form of available nitrogen that is absorbed.

Detailed explanation-4: -Phosphorus is a vital component in the process of plants converting the sun’s energy into food, fiber and oil. Phosphorus plays a key role in photosynthesis, the metabolism of sugars, energy storage and transfer, cell division, cell enlargement and transfer of genetic information.

Detailed explanation-5: -Phosphorus is present in plant and animal cells and is vital to all plants for harvesting the sun’s energy and converting it into growth and reproduction.
