| Question | Answer |
|---|---|
| Cells | The basic unit of structure and function in living things |
| Microscope | An instrument used to make small objects look larger. |
| Cell theory: | A. All living things are composed of cells B. Cells are the basic units of structure and function in living things C. All cells are produced from other cells |
| 2 types of Microscopes | A. Compound Microscope: Focuses light through lenses to produce a magnified image, using two lenses. B. Electron Microscope: Using beams of electrons to produce a magnified image. |
| Magnification | The condition of things appearing larger then they are, using convex lenses (center is thicker than the edges) |
| Resolution | The ability to see to details more clearly, the higher the resolution the sharper the image. |
| Compounds that cells need | A: Organic compounds: carbohydrates, lipids, proteins, and nucleic acids. Organic compounds must contain carbon. B: Inorganic compounds: water. Inorganic compounds DO NOT contain carbon. |
| Carbohydrates | energy rich organic compounds made of carbon, hydrogen, and oxygen. Items that have sugar and starches would be carbohydrates. Examples: potatoes, pasta, rice, and bread. |
| Lipids | ats, oils, and waxes. Examples: whole milk, ice cream, and fried foods. |
| Proteins | large organic molecules made mostly of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. Examples: meat, dairy, fish, nuts, beans |
| Enzymes | a group of proteins that helps speed up chemical reactions in living things. |
| Nucleic Acids | Long organic compounds made of carbon, oxygen, hydrogen, nitrogen, and phosphorus. Nucleic acids contain the instructions that carry out all the functions of life |
| DNA | The genetic material that carries information about an organism and is passed from parent to offspring. Double Helix: Shape of the DNA molecule |
| Water in cells | A. Water is needed for most chemical reactions in cells B. Water helps cells keep their shape. C. Water helps cells maintain their temperature D. Water helps cells carry substances in and out of them |
| Passive Transport | When materials go in and out of the cell WITHOUT using energy. |
| Selectively permeable | means some substances can cross the membrane while others cannot |
| Active transport | When materials go in and out of the cell using energy. |
| Endocytosis | The cell changes shape and engulfs the particle. |
| Exocytosis | The reverse process, which allows large particles to exit the cell. |
