Cell Organization
| Question | Answer |
|---|---|
| Table | a neatly organized display of numbers or words organized into columns and rows |
| Diagram | a neat drawing or photo showing the parts of something with labels and/or written explanations |
| Graph | a visual display of data, usually showing how one variable relates to another; for example a line graph, a scatter plot, or a bar chart |
| Structure | the shape and parts of something and how they’re put together |
| Function | the job something does and how it works |
| Organelle | tiny structure inside a cell that carries out a specialized function (etymology: organ + elle = tiny |
| Nucleus | organelle that contains all the instructions for how to run a cell |
| Cell Membrane | organelle that is the outer boundary of a cell and which only lets certain things in and out |
| Cytoplasm | the liquid filling of a cell in which all of the organelles float (ety: cyto = cell, plasm = jelly) |
| Mitochondrion | organelle that chemically reacts oxygen with sugars to release energy, carbon dioxide, and water |
| Ribosome | organelle that makes proteins for the cell |
| Golgi Body | organelle that packages proteins inside membranes so they can be sent elsewher |
| Endoplasmic Reticulum | organelle that is a folded membrane used to move materials around inside the cell (ety: endo = inside, plasm = jelly, reticu = network |
| Lysosome | organelle that breaks down and gets rid of waste (ety: lyso = cleaning, some = body |
| Vacuole | organelle that stores materials inside the cell (ety: vacu = empty) |
| Chloroplast | organelle in a plant that uses sunlight energy to chemically react carbon dioxide with water to produce sugars and oxygen (ety: chloro = colored + plast = body) |
| Cell Wall | organelle in a plant or bacterium that is outside the cell and gives rigid support and shape to the cell |
| Etymology | the history of a word (language of origin and meanings of root parts of the word) |
| Analogy | a comparison between something simple and something complex to make the complex thing easier to understand |
| Prokaryotic | adjective to describe a cell that has no nucleus or organelles with membranes (ety: pro = before, karyo = kernel) |
| Eukaryotic | adjective to describe a cell that has a nucleus and organelles with membranes (ety: eu = true, karyo =kernel) |
| Unicellular | adjective to describe an organism made of only one cell |
| Multicellular | adjective to describe an organism made of many cells |
| Bacteria | a single celled prokaryotic organism |
| Animal | a multicellular eukaryotic organism that has to consume food to get energy |
| Plant | a multicellular eukaryotic organism that can produce it’s own food and which has specialized organelles: cell wall, chloroplasts, very large vacuol |
| Tissue | a group of cells working together (level of organization in a multicellular organism) |
| Organ | a group of tissues working together (level of organization in a multicellular organism) |
| Organ System | a group of organs working together (level of organization in a multicellular organism) |
