Looking Inside of Cells, and Chemical Compounds in Cells

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
