5. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
8. colourless, odourless, tasteless gas essential to living organisms

11. the site of the light-dependent reactions of photosynthesis with the photosynthetic pigments embedded directly in the membrane.
12. the process by which green plants and certain other organisms transform light energy into chemical energy.

1. an organism deriving its nutritional requirements from complex organic substances.
2. the supportive tissue of an epithelial organ, tumor, gonad, etc., consisting of connective tissues and blood vessels.
3. he cycle of enzyme-catalyzed dark reactions of photosynthesis that occurs in the chloroplasts of plants and in many bacteria and that involves the fixation of carbon dioxide and the formation of a 6-carbon sugar.
