| Question | Answer |
|---|---|
| Organism | An individual living thing such as a plant, animal, fungus, bacterium, archaeon, or protist |
| Living | Condition of being alive |
| Dead | No longer alive |
| Nonliving | Referring to something that has never been alive |
| Energy | The capacity to do work |
| Gas exchange | Process of moving gases into and out of your body |
| Waste | Solids, liquids, or gases that are unusable by the cells of organisms and must be moved out of the cell |
| Environment | Everything that surrounds and influences an organism |
| Adaptation | Any structure or behavior of an organism that allows it to survive in its environment |
| Dormant | State of suspended activity; alive, but inactive |
| Response | An organism’s reaction to a stimulus in the environment |
| 5 NEEDS of all living organisms | 1. Food/energy 2. Water 3. Participates in gas exchange 4. Get rid of waste 5. Suitable environment |
| 3 FUNCTIONS of all living things | 1. Grow 2. Reproduce 3. Responds to environment |
| What is the equation to calculate total magnification? | Objective lens magnification x eyepiece magnification = total magnification |
| 4X x X = X | 10 n' 40 |
| 10X x X = X | 10 n' 100 |
| 40X x X = X | 10 n' 400 |
| Objective Lens: 4X 10X 40X Total Magnification: 40X 100X 400X | Width of Field of View (FOV): 4mm About 1.5mm About 0.4mm |
| Chlorophyll | Green pigment in chloroplasts that captures light energy to make sugars during photosynthesis |
| Paramecia | Ciliated protist that lives in freshwater and eats other tiny organisms for food |
| Multicellular organism | An organism made of more than one cell |
| Single-celled organism | An organism made of one cell that carries out all the functions of living |
| Cell wall | A rigid layer that supports the cell and provides shape |
| Cell membrane | Boundary that controls what enters and leaves the cell |
| Cytoplasm | Internal fluid that contains the cell structures |
| Central vacuole | Membrane that stores water and other substances and provides structure and support for the cell |
| Chloroplast | An organelle that converts the Sun’s energy into food (sugars) |
| Contractile vacuole | Membrane that stores water and expels excess water |
| Food vacuole | Membrane that stores food and merges with a lysosome to digest food |
| Endoplasmic reticulum | Membranous structure that assembles proteins and parts of the cell membrane |
| Mitochondria | Organelle that converts the energy in food into usable energy for the cell |
| Nucleus | Organelle that contains the cell’s genetic material (DNA), which determines the nature of cell structures and substances |
| Ribosome | Structure that makes proteins, free or bound to the endoplasmic reticulum |
| Lysosome | Organelle that digests cellular waste |
| Vacuole | Membrane stores water and other materials |
| Eukaryotes | Organism made of cell or cells that contain a nucleus and organelles |
| Prokaryotes | Single-celled organism that has no nucleus or organelles |
