Looking Inside of Cells, and Chemical Compounds in Cells
| Question | Answer |
|---|---|
| 1. What is any substance that cannot be broken down into simpler substances? | Element |
| 2. What is the smallest unit of an element? | Atom |
| 3. When two or more elements combine chemically, what is it now considered? | Compound |
| 4. What is the smallest unit of compounds? | Molecule |
| 5. Most compounds that contain carbon are called what? | Organic Compounds |
| 6. Compounds that do not contain carbon are called what? | Inorganic Compounds |
| 7. Which organic compound contains only carbon, oxygen, and hydrogen. Examples of this are sugars and starches. | Carbohydrate |
| 8. What organic compound helps many of the organelles in the cell, and is made from the elements carbon, hydrogen, oxygen, nitrogen and sometimes sulfer? | Proteins |
| 9. A protein's molecules are made up of smaller molecules called what? | Amino Acids |
| 10. What is a type of protein that speeds up a chemical reaction in a living thing? | Enzyme |
| 11. Examples are fats, oils, and waxes, these organic compounds are made up of carbon, hydrogen, and oxygen. What am I describing? | Lipids |
| 12. Describe nucleic acids. | They are very large organic molecules made of carbon, hydrogen, oxygen, nitrogen, and phosphorus. Nucleic acids contain the instructions that cells need to carry out all functions of life |
| 13. What is R.N.A. ? | A nucleic acid that play an important role in the production of proteins |
| 14. What is D.N.A. | A nucleic acid that is passed from parent to offspring and directs all of the cell's functions |
| 15. Why is water important for cells? | Without water, most chemical reactions within cells could not take place. Water also helps keep the cell's shapes and sizes |
| 16. What are organelles? | Tiny structures inside of a cell, which carry out specific functions in the cell |
| 17. What is the cell wall? | A rigid layer of nonliving material that surrounds plant cells |
| 18. What is a cell membrane? | The outside boundary for cells without cell walls. The cell membrane is to control what comes in and out of a cell |
| 19. What is a nucleus? | A large, oval structure that acts as the brain of the cell. You can think of it as the control center of a cell |
| 20. What is chromatin? | Thin strands that contain genetic material, or instructions for cell functions that float inside of a nucleus |
| 21. What is a nucleolus? | The tiny ball inside of a nucleus that produces ribosomes |
| 22. What is the region between the cell membrane and the nucleus? | Cytoplasm |
| 23. What are rod-shaped organelles that produce energy, or are known as the "Power Houses" of the cell since they produce energy? | Mitochondria |
| 24. Describe endoplasmic reticulum. | A maze of passageways that carries proteins and other materials from one part of the cell to another |
| 25. What are ribosomes? | Small, grain-like bodies that produce proteins |
| 26. What are golgi bodies? | Collections of sacs and tubes that receives proteins and other materials from the endoplasmic reticulum, and distributes them throughout the cell |
| What are plant cells? | In plant cells, large green structures called chloroplasts capture energy from the sun, and uses the process of photosynthesis to produce glucose/food for the cell |
| What are vacuoles? | A large sac, that stores food and other materials in the cell |
| What are lysosomes? | Small, round structures that break down food and recycle old cell parts |
| What are prokaryotes? What are an example of them? | A cell that lacks a nucleus, bacteria |
| What are eukaryotes? | A cell that has a nucleus |
