Answer: Cell division.

Explanation: Cell division is responsible for the growth of roots in the plant. The growth in the roots of the plant is ultimately the growth of the whole plant.

Roots are very important as it helps in absorption of the nutrients and water from the soil for the growth and development of the whole plant.

The cell division in the plant body leads to the development of the roots, that is found in the soil providing the support to the plant to stand straight in the soil.

sergiy2304 [10]

Answer:

protected; increase

Explanation:

Ozone is composed of trioxygen which is highly reactive gas compared to dioxygen. Ozone layer is present in stratosphere and troposphere and protect the humans from ultraviolet radiations but it may be toxic if inhaled. Ozone can be broken down into molecular oxygen by chlorine and bromine atoms.

A hole was discovered in ozone layer in 1982 and scientist believed that it could be dangerous for human health. The compounds involved in depletion of ozone are mainly Chlorofluorocarbons (CFS) and (HFCS). Then a global agreement was signed in 1987 which leads to prohibition of use of all chemicals that are involved in depletion of ozone layer. The problem of ozone depletion is solved by the agreement and ozone hole started to recover it from 2000.

But recent reports showed that the alternative chemicals used to protect the depletion of ozone layer began to trap the heat inside the earth like greenhouse effect. Now scientists are in search of chemical that can prevent both ozone depletion as well as global warming.
