Concept:Photosynthesis occurs in a plant organelle that contains chlorophyll to absorb light energy.
Explanation:The chloroplast is a double-membrane organelle found in plant cells.
It contains chlorophyll, the green pigment that captures sunlight.
This light energy is used to convert carbon dioxide and water into glucose and oxygen.
Therefore, the chloroplast is the exact site where photosynthesis takes place.
Ribosomes are responsible for protein synthesis and do not perform photosynthesis.
Cytoplasm is the jelly-like fluid that fills the cell but is not the site of photosynthesis.
Mitochondria are the sites of cellular respiration, where glucose is broken down to release energy.
Among the given options, only chloroplasts match the function.
Answer:Chloroplasts (Option A).
