Plants
-Autotrophic=An organism capable of synthesising it’s own food from organic substances using light or
chemical energy
-Sessile=Without a stalk, pedicel or petiole
Photosynthesis
-Photosynthesis is the process by which plant cells make sugar (glucose) using sunlight energy, water and
carbon dioxide.
-The sugar is then transported to all parts of the plant and used as an energy source for growth and survival, or
stored as starch for later use.
-Animals eating plants obtain this ready-made energy source.
