PLEASE HELP! Use two examples for plants to explain how the development of new technologies such as radioisotopes has increased our knowlegde of reactions in plants.​

The radioactive isotopes can be used to track many physiological functions and chemical reactions occurring within the cells of the living organisms including plants.

Explanation:

Phosphorus uptake by the plants: Phosphorus is an essential mineral required by the plants for their growth and metabolism. The radioactive phosphorus-32 can be used to track back the rate at which the plant absorbs the phosphorus from the soil. This can help scientists to identify plants that can absorb phosphorus more quickly.

Pesticides levels in the plants: The pesticides levels in the plants can be traced by using radioisotopes such as chlorine-36. This can be used to trace the fact that how much of pesticide is present in the soil and how much of it is utilized by the plants. This is helpful identifying the fact that which pesticide is useful for the growth of the plants.
