Biology
In which of the following cellular structures does photosynthesis occur ?
- Chromoplast
- Chromosome
- Chloroplast
- Leukoplast
Answer
Chloroplast
Reason — Photosynthesis occurs in the mesophyll cells of the leaf. These cells contain numerous plastids called chloroplasts.
Chromoplasts are plastids that store pigments (like carotenoids) and give color to fruits and flowers. They do not carry out photosynthesis. Chromosomes are found in the nucleus and contain genetic material (DNA). They are not involved in photosynthesis. Leukoplasts are colorless plastids involved in storage of starch, oils, or proteins, not in photosynthesis.
