Cell Test 2025
Cell Test 2025 Study Guide
| Term | Definition |
|---|---|
| Animal | Living things that are multicellular, have nucleus, do not have cell walls, and are consumers. |
| Bacteria | Single celled microorganism that has a cell wall but no nucleus. |
| Cell | The Basic unit of life found in all living things. |
| Cell Membrane | Gives the cell its shape and controls what goes through it such as food, water, oxygen, and wastes. |
| Cell Wall | A rigid layer of nonliving material that surrounds plant cells. |
| Chlorophyll | A green pigment found in the chloroplasts of plants. algae and some bacteria. |
| Chloroplast | The part in plant cells that captures energy from sunlight and uses it to produce. |
| Cytoplasm | The gel-like- fluid that contains all the cell's organelles. |
| Diffusion | The movement of molecules through a membrane from an area of higher concentration to an area of lower concentration. |
| Fungai | Living things that have a nucleus, cell walll,. are usually multicellular, and get their food from dead and organic matter (ex: mushrooms, yeast). |
| Microorganism | A living thing that can only be seen with a microscope. |
| Mitochondria | The parts of the cell that help change food into energy. |
| Multicellular | Living things that are made of many cells. |
| Nucleus | The cells' control centre. |
| Nuclear Membrane | Surrounds the nucleus and controls what goes into and comes out of the nucleus. |
| Organelle | A tiny cell structure that carries out a specific function within the cell. |
| Osmosis | The movement of water molecules through selectively permeable barrier. |
| Photosynthesis | The process by which plants capture light energy from the sun and use it to make food. |
| Protists | Living things that have a nucleus, are usually singled celled microorganisms, and are not plants, animals or fungus. (ex: amoeba, paramecium) |
| Selectively Permeable | A property of cell membranes that allows some substances to pass through, while others cannot. |
| Specialised Cell | Cell that carries out a specific function within an organism. |
| Tissue | A group of specialised cells. |
| Vacuole | A sac inside a cell that stores food. |
| Prokaryotic | Cells were here first and for billions of years and were the only form of life. |
| Eukaryotic | Cells came next and are more complex. Most of the living things that we are familiar with are made of eukaryotic cells; animals, plants, fungi and protists. |
| Red Blood cells | Carry life-giving oxygen to every corner of your body. |
| White Blood Cells | Kills germs. |
| Intestinal Cells | Squirt out chemicals that chisel away at your food so you can absorb its nutrients. |
| Nerve Cells | Slings chemicals and electrical messages that allow you to think and move. |
| Heart Cell | Constantly pump blood. |
| Procaryotic | Cells that were here first and were the only form of life. |
| What do cells have in common? | They all have cell membrane, DNA, a cytoplasm, and they get energy and nutrients from their environment. |
| Why is it important for a cell to be small | So they can be replaced easily. Cell respiration. |
| What is the advantage to be multicellular and why is that important? | A longer life spam. |
| What are the three parts that belong to the brain of the cell or the nucleus and what do they do? | Nucleus, Nucleoules, Chromotin. |
| What are the small, grain-like bodies that are everywhere in the cell? | Ribosome |
| What cells have the most mitochondria. the animal call or the plant cell and why? | An animal cell has an average of 1000 to 2000 mitochondria, while a plant cell has an average of 300 to 450 mitochondria |
| What are the three main concepts of the cell theory? | cells are the basic unit of life, all living things are made up of cells, and all cells come from other cells. |
| Are organelles living things? | Nonliving |
| Do animals and plant cell have all of the same organelle? | Animal cells have another set of organelles not found in plant cells |
| Why would your heart cells ave more mitochondria than your eye cells? | Because they need more energy. |
| How do mitochondria and chloroplast different? What's the theme? | Mitochondria has nothing to do for the sun. They gather nutrients. |
| Why is it unnecessary for our cell to have a cell wall? | They would be incapable of movement. |
| What might happen if the lysosomes inside a cell stopped working properly? | These sugars and fats build up in the cell instead of being used or excreted. |
