Chlorophyll is present in the Thylakoid membrane.

Here's a step-by-step explanation:

1. Chloroplasts, found in plant cells, are the sites where photosynthesis occurs.

2. Each chloroplast is enclosed by an envelope that consists of an inner and an outer membrane.

3. Inside the chloroplasts are stacks of thylakoids, which are like the chloroplast's little solar panels.

4. The thylakoids are where the light-dependent reactions of photosynthesis occur.

5. The thylakoid membrane houses chlorophyll, a pigment that absorbs light energy for photosynthesis.

6. Therefore, chlorophyll is present in the thylakoid membrane, not in the intra thylakoid space, intermembrane space, or inner membrane of the envelope.
