Question

How do the plants take in other raw materials like nitrogen, phosphorus and magnesium for building their body?

Answer 1

Answer:

The leaves have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesis (prepare) food from carbon dioxide and water. Since the synthesis of food occurs in the presence o f sunlight , it is called photosynthesis (Photo: light; synthesis : to combine).

Explanation:

Nitrogen assimilation in plants. Plants absorb nitrogen from the soil in the form of nitrate (NO3−) and ammonium (NH4+). ... Nitrogen is transported from the root to the shoot via the xylem in the form of nitrate, dissolved ammonia and amino acids.

Plant roots absorb phosphorus from the soil solution. ... In general, roots absorb phosphorus in the form of phosphate, but can also absorb certain forms of organic phosphorus. Phosphorus moves to the root surface through diffusion.

Magnesium is one of thirteen mineral nutrients that come from soil, and when dissolved in water, is absorbed through the plant's roots. Sometimes there are not enough mineral nutrients in soil and it is necessary to fertilize in order to replenish these elements and provide additional magnesium for plants

Answer 2

Answer:

The answer to the given question is as follows:-

So,when the plant carry out the process of photosynthesis it takes the Co2 from the atmosphere. And according to the given question nitrogen is a gaseous substance so plant takes the nitrogen at the time of the respiration in the night which is required for the growth of the plant. We also know that when there is lightning in the sky at that time the nitrogen in the atmosphere comes to the ground due to the lightning. Then the bacteria in the root of the plants absorb the nitrogen and at that time nitrogen fixation happens & nitrogen is used by the plants for their growth. In this way the plants takes the nitrogen from the atmosphere.After that the Phosphorus and magnesium are the other valuable substances that are required for the growth of the plant and the plant takes it in the

time when it takes the water from the soil. In the water there may be the presence of magnesium and phosphorus and due to which the plant can take the magnesium and phosphorus. And if in the water there is no availability of magnesium and phosphorus then the fertilizer containing the Phosphorus(Ph) and magnesium(Mg) is given to the plant for their growth.....and development.
