- 1. A simple sugar which is an important energy source in living organisms and is a component of many carbohydrates
- 2. The complex reaction which plants use to turn energy from the sun
- 5. The peripheral '.....' consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to the heart

- 11. a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, typically growing in a permanent site, absorbing water and inorganic substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll
- 12. a living organism which feeds on organic matter, typically having specialized sense organs and nervous system and able to respond rapidly to stimuli
