Synthesis: Putting together

Photosynthesis: The process by which plants make their own food.

Proccess of Photosynthesis: Photosynthesis takes place in the leaves of plants. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast has chemical called chlorophyll which gives leaves their green color. The chlorophyll absorbs the suns energy. Oxygen is then realesedd from the leaves. Hydrogen and carbon dioxide are then used to form glucose, which is food for the plants. Sometimes the glucose is also used for growth and development of the plants.

Proccess of Respiration in Plants: Plant cells respire, just as animal cells do. If theey stop respiring, they will die. Respiration uses oxygen and produces carbon dioxide. Photosynthesis uses carbon dioxide and produces oxygen. It also depends on how much light there is. Plants only respire if there is sunlight, and don't respire in the night.

Proccess of Respiration in Animals: Every cell in an animal requires oxygen to perform cellular respiration. Cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products.

Light energy: The only form of energy we can see. It is formed through chemical, radiation, and mechanical means.

Carbon Dioxide: A colorless and odorless gas that is vital to life on Earth.

Water: A nearly clear substance that is nessecary for life.

Stoma: A tiny opening or pore that is used for gas exchange.

Chloroplasts: The food producers of the cell.

Chlorophyll: A green pigment, present in all green plants and in cyanobacteria

Glucose: A simple sugar with the molecular formula C6H12O6.

ATP: Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to basically do everything.





Glucose is used up during cellular respiration to provide the plant with energy
