Question

Determine which of the following less toxic in plants when it remains inside it for along time

1-co2
2-o2
3-ammonia
4-all the above
​

Answer 1

Out of the options provided, carbon dioxide (CO2) is less toxic to plants when it remains inside for a long time.

Plants require CO2 to carry out photosynthesis, which is the process by which they convert light energy into chemical energy. As long as the concentration of CO2 is not too high, it is not toxic to plants and can actually be beneficial for their growth.

On the other hand, high levels of oxygen (O2) can be toxic to plants and can lead to the formation of reactive oxygen species that can damage the plant's cells. Similarly, high levels of ammonia (NH3) can also be toxic to plants and can lead to chlorosis, stunted growth, and even death.

Therefore, option 1 (CO2) is the correct answer.
