Which structures inside plant cells are primarily responsible for photosynthesis?

B
Chloroplasts
C
Ribosomes
D
Mitochondria
Verified step by step guidance1
Identify the process in question: Photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose.
Understand the role of each cell structure: The nucleus contains genetic material and controls cell activities, ribosomes are involved in protein synthesis, mitochondria are responsible for cellular respiration, and chloroplasts are the site of photosynthesis.
Focus on chloroplasts: Chloroplasts contain chlorophyll, the green pigment that captures light energy, and are the organelles where photosynthesis occurs.
Recognize the components of chloroplasts: Chloroplasts have thylakoid membranes where the light-dependent reactions take place, and the stroma where the Calvin cycle (light-independent reactions) occurs.
Conclude that chloroplasts are the structures primarily responsible for photosynthesis in plant cells.
