Is chlorophyll needed for light dependent?

In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.

How does photosynthesis depend on light and chlorophyll?

The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.

Why is photosynthesis a light-dependent reaction?

Explanation: Light reactions of photosynthesis are light dependent reactions. They are light dependent because for the process to start, a light ray should impinge on the chlorophyll and only then the reactions of photosynthesis begin.

Are light-dependent reactions in chloroplasts?

Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions.

Why are chloroplasts important in light dependent reactions?

Being Green. Chlorophyll, a green pigment found in chloroplasts, is an important part of the light-dependent reactions. Chlorophyll soaks up the energy from sunlight. It is also the reason why plants are green. You may remember that colors are different wavelengths of light.

Why does chlorophyll reflect different wavelengths of light?

Chlorophyll soaks up the energy from sunlight. It is also the reason why plants are green. You may remember that colors are different wavelengths of light. Chlorophyll captures red and blue wavelengths of light and reflects the green wavelengths.

What are chloroplasts and what do they do in plants?

Chlorophyll: the pigment that gives plants their green color and allows them to absorb sunlight… more (link is external) Chloroplast: a part of a cell found in plants that converts light energy into energy plants can use (sugar). Other living organisms such as algae also have cells that contain chloroplasts.

When does light enter the process of photosynthesis?

Light energy enters the process of photosynthesis when pigments absorb the light. In plants, pigment molecules absorb only visible light for photosynthesis. The visible light seen by humans as white light actually exists in a rainbow of colors.
