Correct option is C
The correct answer is (c) Chloroplast. Chloroplasts are the organelles in plant cells that contain chlorophyll, the green pigment essential for photosynthesis. Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, and converts it into chemical energy through a series of reactions within the chloroplasts. These organelles are the sites where light-dependent and light-independent (Calvin cycle) reactions of photosynthesis occur, leading to the production of glucose and oxygen.
Information Booster: ● Chloroplasts are double-membrane structures found in the cells of green plants and algae. ● Inside chloroplasts are thylakoid membranes, where chlorophyll is embedded, forming structures called grana. ● The stroma is the fluid surrounding the thylakoids, where the Calvin cycle (light-independent reactions) takes place. ● Chloroplasts have their own DNA and ribosomes, similar to mitochondria, supporting the theory that they evolved from ancient cyanobacteria (endosymbiotic theory). ● The presence of chlorophyll in chloroplasts gives plants their green color and is crucial for absorbing sunlight for energy. ● The chemical energy produced is stored in the form of ATP and NADPH, which are used in the synthesis of glucose.
