Biology Unit 2
Across
- 4. two or more atoms bonded together
- 8. the amount of photosynthesis that is done in an area
- 10. compound used by cells to store and release energy; made during cellular respiration
- 12. Type of energy holding atoms together
- 16. organelles in plant cells that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis
- 18. unicellular organism that lacks a nucleus
- 21. Process by which some organisms, such as certain bacteria, use chemical energy to produce carbohydrates
- 22. A very large organic molecule composed of many smaller molecules. Carbohydrates, Lipids, Proteins & Nucleic Acids
- 27. organism whose cells contain a nucleus and membrane bound organelles
- 28. The process in which our cells break down food and turn it into energy that cells need to perform their life functions. Oxygen is needed for this process.
- 30. macromolecule made mostly from carbon and hydrogen atoms; provides long-term energy (includes fats, oils, and waxes)
- 31. process by which organisms maintain a relatively stable internal environment
- 32. Anything that has mass and takes up space (the letters)
Down
- 1. An organelle found in large numbers in most cells, in which the processes of cellular respiration and energy production occur.
- 2. Process that requires oxygen
- 3. a large, fluid-filled organelle that stores not only water but also enzymes, metabolic wastes, and other materials
- 5. the substance that controls the quantity of product that can form in a chemical reaction
- 6. The process that converts light energy into chemical energy that is stored in glucose or other organic compounds; occurs in plants, algae, and certain prokaryotes.
- 7. An organism that obtains organic food molecules by eating other organisms or substances derived from them.
- 9. Basic unit of matter
- 11. A molecule FORMED as a result of a chemical reaction (outputs)
- 13. the process by which cells obtain energy from an energy source without using oxygen
- 14. A simple sugar made in the process of photosynthesis which the plants use for energy in Cellular Respiration.
- 15. Green pigment located in membranes within the chloroplasts of plants and algae and in the membranes of certain prokaryotes.
- 17. macromolecules containing hydrogen, oxygen, nitrogen, carbon, and phosphorus (includes DNA and RNA)
- 19. An organism capable of making its own food
- 20. macromolecule that contains carbon, hydrogen, and oxygen. Provides short-term energy (includes starches like potatoes and pasta)
- 23. Pores on the leaf where O2 exits and CO2 enters
- 24. macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed by the body for growth and repair
- 25. elements or compounds that ENTER into a chemical reaction (inputs)
- 26. Found in the bonds that hold molecules together (the lines)
- 29. Process that does not require oxygen
