Which organelle in a plant cell is primarily responsible for carrying out photosynthesis?

• A. Chloroplast
• B. Golgi apparatus
• C. Rough endoplasmic reticulum
• D. Mitochondrion

Answer: (A)

Verified step by step guidance

1. Identify the function of each organelle listed in the problem: Golgi apparatus, Rough endoplasmic reticulum, Mitochondrion, and Chloroplast.
2. Recall that the Golgi apparatus is mainly involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell.
3. Understand that the Rough endoplasmic reticulum is responsible for synthesizing proteins, especially those destined for membranes or secretion.
4. Know that the Mitochondrion is the powerhouse of the cell, generating ATP through cellular respiration but not involved in photosynthesis.
5. Recognize that the Chloroplast contains chlorophyll and is the site where photosynthesis occurs, converting light energy into chemical energy.
