Chloroplast
Structure:
Two membranes contain and protect the inside of the chloroplast. Inside the stroma, an area inside the chloroplast, chemical reactions take place and sugars are created. A stack of Thylakoids is called Granum. On the surface of the thylakoids, there are chlorophyll molecules. The stacks are connected by stroma lamellae. They keep the stacks at a safe distance from each other and maximize the efficiency of the cell.
Function:
It is the food making structure of a plant cell. The chlorophyll molecules absorb the sun's energy and converts it to chemical energy which can then be used to fuel chemical reactions within the cell. In other words the chloroplast is involved in photosynthesis.

In relation to other organelles:
The chloroplast provides the chemical energy and food source for the whole cell. It is vital in the fact that without it, photosynthesis cannot take place.
Extra:
In theory, the parts of the plant that are located above ground (the parts other than the roots) would have a greater abundance of chloroplasts. This is due to the fact that these cells are exposed to sunlight. If the chloroplast does not work, the cell will die from lack of energy. Over time the evolution of the chloroplast has helped increase the efficiency of food production within the cell.
