Across
- 1. carbon-containing molecules, such as carbohydrates, lipids, proteins, and nucleic acids that form the basis of life
- 4. short-term energy carrier; temporarily stores energy during photosynthesis
- 9. fluid connective tissue that circulates throughout the body through blood vessels
- 10. organic molecules, such as glucose, that organisms use for chemical energy
- 11. the simplest form of matter that has a unique set of properties
- 12. energy-carrying molecule that cells use to power their metabolic processes; provides the cell with an immediate usable form of energy
- 13. a biochemical process in which cells break down glucose and oxygen to make carbon dioxide, water, and ATP for energy
- 16. an individual living thing
- 17. part of a biogeochemical cycle that holds an element or water for a long period of time; for example, the atmosphere is a reservoir for carbon dioxide
- 19. green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis
- 21. double-stranded nucleic acid that stores genetic information; also known as deoxyribonucleic acid
- 22. organic compound that supplies energy to the body, such as sugar and starch
- 23. the ability to do work
Down
- 2. simple sugar that all living things use to store and transport energy
- 3. sharing of electrons between two atoms that holds the atoms together
- 5. type of organism that uses light energy or chemical energy to make food for itself and other organisms
- 6. organic compound made up of amino acids
- 7. modified front legs, or forelimbs, that are adaptations for flight
- 8. sweet, sugary liquid produced by the flowers of many angiosperms to attract animal pollinators
- 14. aquatic, ectothermic vertebrate that is covered with scales and has gills to absorb oxygen from water
- 15. basic unit of structure and function of living things
- 18. an atom or group of bonded atoms that has a positive or negative charge
- 20. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar.
