Verified step by step guidance

Understand the process of photosynthesis: Photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose. This process requires light, carbon dioxide, and water.

Identify the organelle responsible for photosynthesis: In plant cells, the organelle that contains the pigment chlorophyll, which captures light energy, is the chloroplast.

Review the structure of the chloroplast: Chloroplasts have a double membrane and contain internal structures called thylakoids, which are stacked into grana. The thylakoid membranes house the photosynthetic pigments and enzymes necessary for the light-dependent reactions.

Differentiate the roles of other organelles: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids. The nucleus stores genetic material and regulates cellular activities. The mitochondrion is responsible for energy production through cellular respiration, not photosynthesis.

Conclude that the chloroplast is the correct answer: Based on the function and structure of the chloroplast, it is the organelle primarily responsible for photosynthesis in plant cells.
