Here's why:
* Chloroplasts: These are organelles found specifically in plant cells. They are responsible for photosynthesis, the process by which plants convert light energy into chemical energy.
* Chlorophyll: This is a green pigment located within the chloroplasts. It absorbs light energy, primarily in the red and blue wavelengths, which is essential for photosynthesis.
While some other organisms, like algae, also have chloroplasts and chlorophyll, they are not considered plant cells.
