Cumulative from Unit 1 and Unit 2
Across
- 5. A cancerous tumor that can invade nearby tissues and spread to other parts of the body.
- 6. A solution that doesn't change a cell's water content.
- 7. 2 layers make up the plasma membrane of our cells.
- 12. The rough endoplasmic reticulum is a busy place covered in tiny dots (ribosomes). It's where the cell makes and fine tunes proteins, kind of like a protein factory.
- 13. The smallest part of an element that still has the properties of that element.
- 18. Moving stuff in and out of cells without using energy.
- 19. The cell wall is like the outer armor of a plant cell. It's strong and rigid, giving the cell shape and protection.
- 20. The movement of water through a cell membrane.
- 21. Using energy to move stuff in and out of cells, even against the flow.
- 22. What gets dissolved in a solution.
- 24. "Water fearing"; a substance that does not have an affinity for water.
- 25. What does the dissolving in a solution.
- 26. Mitochondria are the cell's power stations. They make energy (ATP) so the cell can do its work.
- 30. What is deliberately changed or manipulated in an investigation.
Down
- 1. Eukaryotic cells are like the advanced cells. They have a proper nucleus that holds the cell's instructions (DNA) and many other specialized parts. You can find them in animals, plants, fungi, and more complex life forms.
- 2. Undifferentiated cells that can become differentiated into one or more types of specialized cells.
- 3. Large organic molecules that make up all living things.
- 4. Informational molecules that store and express our genetic information; we get this from our parents and NOT our food.
- 8. Single sugar molecule; the monomer of carbohydrates.
- 9. Group(s) being tested.
- 10. Flagella are whip-like tails on some cells. They spin or whip around to help the cell move. Imagine them as the propeller on a motorboat.
- 11. Aspects of an experiment that are kept constant/consistent.
- 14. The process of cell division, where one cell splits into two identical cells.
- 15. Cancer-causing agents.
- 16. Larger nucleic acid; never broken down for energy.
- 17. Standard/"normal" group used for comparison.
- 23. The need of an organism to stay stable by regulating internal conditions.
- 27. When chromosomes split and move to opposite sides of the cell during mitosis.
- 28. Anything that has mass and occupies space.
- 29. The application of scientific discoveries to meet human needs and goals through the development of products and processes.
