photosynthesis

Phenomenon by which the plant, helped by solar energy, obtains its food (glucose) from the air and the soil and releases oxygen into the atmosphere.

solar energy

Energy derived from sunlight and absorbed through the chlorophyll, the green pigment found in plant leaves.

stem

Main part of the plant, extending from the soil to the terminal bud.

absorption of water and mineral salts

Water and mineral salts are absorbed through the roots and carried up to the leaves by the stem and its offshoots.

carbon dioxide absorption

The carbon dioxide in the atmosphere required for photosynthesis is absorbed by the leaf.

glucose

Organic food produced through photosynthesis and used by the plant to ensure growth; it is transported throughout the plant by the sap.

release of oxygen

The process of photosynthesis releases oxygen, a gas essential to life.

leaf

Part of the plant where photosynthesis takes place; it also helps oxygenate the ambient air and reduce carbon dioxide.
