The Uses of Plants

Without plants, the web of life cannot exist. Basic Part of the Food Chain Most of our clothing comes from Plants Our homes are constructed primarily from plant

materials. Many of our recreational activities revolve around

plants. Plants are essential in cooling our planet, purifying

our air and the production of oxygen.

Propagation is defined as:   ?    The only way to propagate some species

and cultivars.   ?    The process of increasing the number of a

species.   ?    The union of an egg and sperm.   ?    A cheaper method of propagation than with

seeds.
