Does a cucumber have chloroplast?

Yes, cucumbers have chloroplasts.

Chloroplasts are organelles that are found in plant cells and are responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll, a green pigment that absorbs sunlight, and other pigments that reflect sunlight. The cucumber plant is a green plant, which means that it has a lot of chloroplasts in its cells. This allows the cucumber plant to photosynthesize and produce the food that it needs to grow and reproduce.
