PHOTOSYNTHESIS




And he shall be as the light of the morning, when the sun riseth, even a morning without clouds; as the tender grass springing out of the earth by clear shining after rain.(2 Samuel 23:4)


What Do Plants Need to Make Food?Plants need several things to make their own food. 


They need:chlorophyll, a green pigment found in the leaves of plants (see the layer of chlorophyll in the cross-section of a leaf below)




light (either natural sunlight or artificial light, like from a light bulb)

He is green before the sun, and his branch shooteth forth in his garden.His roots are wrapped about the heap, and seeth the place of stones. (Job 8:16-17)

carbon dioxide (CO2)(a gas found in the air; one of the gases people and animals breathe out when they exhale)

water (which the plant collects through its roots)

nutrients and minerals (which the plant collects from the soil through its roots)

Plants make food in their leaves. The leaves contain a pigment called chlorophyll, which colors the leaves green. Chlorophyll can make food the plant can use from carbon dioxide, water, nutrients, and energy from sunlight. This process is called photosynthesis.



During the process of photosynthesis, plants release oxygen into the air. People and animals need oxygen to breathe.
