Question

What is required for LIGHT DEPENDENT reactions to occur in plants?

Answer 1

Answer: In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.

Explanation:

Answer 2

The light dependent reaction mainly include sunlight, chlorophyll, thakaloids.

Light-dependent reactions

• When sunlight hits a molecule of chlorophyll.
• The excited photon that are present in light also excites an electron which leaves the chlorophyll molecule.
• These electron then travel  travels along the thylakoid membrane via a series of carrier proteins.

This  reactions convert light energy into chemical energy,  also known as photosynthesis.

Plant by the process of  photosynthesis collect energy from the sun and break down water molecules to produce ATP and NADPH.

These two energy-storing molecules are then used in the light-independent reactions and maintain the cycle. some of these energy get used by the plants for make the food.

Therefore, the light dependent reaction mainly include sunlight, chlorophyll, and thakaloids.
