More Information ⭐

Photosynthesis is the process through which plants make their own food. They take in carbon- dioxide which is released by animals and humans. This happens in the presence of chlorophyll, sunlight and water.

The process of photosynthesis only happens during day time because:

• This process needs sunlight.
• And sunlight is only present during day time.
• Hence, it only happens during day time.

So, now might the question arrise what do the plants release at night oxygen/ carbon dioxide?

At night plants don't do the process of photosynthesis. So, they do respiration.

What is respiration?

It is an act of inhaling and exhaling air and release CO2 to get energy.
