Which of the following contains the green pigments used in photosynthesis?

The chloroplast is the organelle responsible for photosynthesis in plants and some algae. It contains chlorophyll, the green pigment that captures light energy from the sun. This process is essential for converting light energy into chemical energy in the form of glucose, which serves as food for the plant. The presence of chlorophyll gives chloroplasts their characteristic green color, highlighting their role in capturing sunlight for the photosynthesis process.

In contrast, mitochondria are involved in cellular respiration and energy production but do not participate in photosynthesis. Ribosomes are the sites of protein synthesis within the cell and do not contain any pigments. The nucleus serves as the control center for the cell, housing genetic material, but it also does not involve pigments related to photosynthesis. Thus, the chloroplast stands out as the only option that contains the green pigments necessary for this critical biological process.
