Photosynthesis in a leaf: Chloroplasts, Grana, Stroma, and Thylakoids, the starting point for energy's travels through life

Plants absorb water through their roots, and carbon dioxide through their leaves. Some glucose is used for respiration, while some is converted into insoluble for storage. The stored starch can later be turned back into glucose and used in respiration. Oxygen is released as a by-product of photosynthesis.
When the stomata are shut (guard cells lack water), there is no space for gasses to move in and out of the leaf, limiting the rate of photosynthesis (as CO
LEAVES AND PHOTOSYNTHESIS - The Student Room
1. Photosynthesis is the most important chemical process in the world. Without it, plants and people could not exist.
2. A plant’s leaves are vital for its survival. Most of the photosynthesis process takes place in the leaves of a plant.
Leaves enable photosynthesis to happen. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce carbohydrate (food) for plants to grow. Leaves are adapted to perform their function eg they have a large surface area to absorb sunlight.

When a plant combines water, carbon dioxide and sun-energy to make the glucose there is always something left over. It is called oxygen—the very same oxygen we need to breathe. Because the plants don’t need it, they get rid of it. When a plant gets rid of the oxygen they don’t need, it is called respiration. A plant gets rid of oxygen through its leaves, stems and flowers, fruits or vegetables. And when they do, we have the oxygen we need. Thanks, plants~Photosynthesis facts
The concentration of glucose within the leaf is high when photosynthesis has just occurred, and diffusion involves the movement of molecules from an area of high concentration to an area of low concentration.

Key to photosynthesis is the presence of chlorophyll, a pigment which resides in the chloroplasts within plant cells. Chlorophyll is green, which is why most leaves are green (other pigments within the leaf are red, orange or yellow and these are sometimes more numerous, giving a different leaf colour, or show through when the chlorophyll pigments break down in autumn, hence the leaves changing colour). The primary sites for photosynthesis are on the leaves, although chloroplasts are generally also quite numerous in external stem cells.

The process of photosynthesis uses light, water and carbon dioxide in a series of two reactions; light reaction (which can only happen when light is available) and carbon fixation (which doesn’t require light). The net result of photosynthesis is the production of sugars (either in the form of glucose to be used, sucrose to be transported to other parts of the plant or starch to be stored) and the release of oxygen.

This process uses the sugars produced by photosynthesis and converts them into energy which the plant can use (this energy is contained within molecules called ATP – adenosine triphosphate). Oxygen is used in these reactions and, as well as charged up ATP molecules, the process releases water and carbon dioxide.
