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.
