Chlorophyll: a group of green pigments found in photosynthetic organisms.
Parasite: an organism that derives its food from, and lives in or on, another living organism at the host’s expense.
Photosynthesis: metabolic process characteristic of plants in which carbon dioxide is broken down, using energy from sunlight absorbed by the green pigment chlorophyll. Organic compounds are made and oxygen is given off as a by-product.
