Which structure in plant cells contains chlorophyll?

Chloroplasts are specialized organelles in plant cells that contain chlorophyll, the green pigment crucial for the process of photosynthesis. This process allows plants to capture light energy from the sun and convert it into chemical energy in the form of glucose, which serves as food for the plant. Chlorophyll plays a key role in absorbing light, particularly in the blue and red wavelengths, while reflecting green light, which is why plants appear green.

Other cell structures mentioned do not contain chlorophyll and have different functions. Mitochondria are known as the powerhouse of the cell, generating energy through cellular respiration. The nucleus houses the cell's genetic material and controls its activities. The cell wall provides structural support and protection but does not participate in photosynthesis or contain chlorophyll. Understanding the specific roles of these organelles is essential for grasping how plant cells function as a whole.
