photosynthesis (Noun)
The process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide , water, and light energy in chloroplasts.

photosynthesis
Process by which plants transform carbon dioxide and water into carbohydrates and other compounds, using energy from the sun captured by chlorophyll in the plant.

Photosynthesis is a process used by plants, some protists, and some bacteria to make food. It makes glucose (a kind of sugar) and oxygen from carbon dioxide in the air and water. Cells (very small parts that make up a plant or animal) use it to create energy to live.

Summary of the process.

Photosynthesis starts when light touches a green part of a plant. Each green cell has small parts called chloroplasts inside of them. Single photons of light hit green chemicals in the chloroplast, causing an enzyme to break apart water. Water, when broken, makes oxygen, hydrogen, and energy. The energy is used by a protein that lets light into the cell. The light cannot get out of the cell until another protein lets them, and this protein uses the energy from the escaping light to make ATP. While this is happening, the hydrogen and oxygen join broken up carbon dioxide to form glucose. This glucose is later used in cellular respiration to form more ATP. Without Photosynthesis, much of the world wouldn't be alive. Everyone and everything needs the oxygen produced by photosynthesis to live.

Plants, some Bacteria and Protists make food through Photosynthesis, this is where plants turn Carbon Dioxide and Water into Glucose – Sugar of sorts – using the energy in Sunlight, Oxygen is a waste product.
