Vacuoles are small sacs are filled with food and water. They are used by cells as storage tanks. All plant cells have vacuoles, but not all animal cells do. The primary place where plants store water is within its vacuoles. When a plants vacuoles are filled with water, they become plump, giving the plant strength. What happens when you do not water a plant? It begins to wilt, becoming softer. This is because the vacuoles found inside the plants cells are running out of water.
When you look at a plant, what color do you most often see? What makes plants green? The last organelle we will explore is the Chloroplast. A chloroplast is a small pill shaped organelle found only in plants. Chloroplasts are green because they are filled with a green pigment, or chemical called Chlorophyll. Chlorophyll is used by a plant to capture energy from the sun, which can later be used to create food.
Even though chloroplasts are very small, they can be seen from outer space. Chloroplasts are what help to give the Earth a green color.
