Photosynthesis occurs in chloroplasts, which are specialized organelles found in the cells of green plants and some algae. These structures contain chlorophyll, the green pigment that captures light energy, allowing the plant to convert carbon dioxide and water into glucose and oxygen, using sunlight as the energy source. This process is essential for producing the food that plants need to grow and thrive, as well as for generating oxygen, which is vital for most living organisms.

In contrast, mitochondria are involved in cellular respiration, where they convert glucose into ATP (the energy currency of the cell) but do not participate in photosynthesis. Ribosomes are the sites of protein synthesis, crucial for translating genetic information into proteins but unrelated to the photosynthetic process. The endoplasmic reticulum is involved in the synthesis and transport of lipids and proteins but does not play a direct role in photosynthesis. Understanding these differences highlights the unique function of chloroplasts in the energy conversion processes of plants.
