In what organelles does photosynthesis take place in a eukaryotic cell?

Photosynthesis in a eukaryotic cell takes place in the organelle known as the chloroplast. Here are the steps:

1. Light-Dependent Reactions: The first stage of photosynthesis occurs in the thylakoid membrane of the chloroplast. Here, light energy is absorbed by chlorophyll and other pigments, water molecules are split to release oxygen, and ATP (energy currency of the cell) and NADPH (an electron carrier) are produced.

2. Calvin Cycle (Light-Independent Reactions): The second stage of photosynthesis occurs in the stroma of the chloroplast. Here, the ATP and NADPH produced in the first stage are used to convert carbon dioxide into glucose, a type of sugar that the plant can use for energy.

So, in summary, photosynthesis in eukaryotic cells takes place in the chloroplasts, specifically within the thylakoid membrane and the stroma.
