| Question | Answer |
|---|---|
| Cell | A basic unit of structure and function in living things |
| microscope | An instrument that makes small objects look larger |
| cell theory | A widely accepted explanation of the relationship between cells and living things |
| cell wall | A rigid supporting layer that surrounds the cells of plants and some other organismos |
| cell membrane | a thin flexible barrier that surround a cell and controls which pass into and out of a cell |
| nucleus | In cells a large oval organelle that contains the cell genetic material in the form of DNA and controls many of the cells activities |
| organelle | A tiny cell structure that carriers out a specific function within the cell |
| ribosome | A small grain shaped organelle in the cytoplasm of a cell that produces proteins |
| cytoplasm | The thick fluid region a cell located inside of the cell membrane |
| mitochondria | Rod shaped organelles that convert energy in food molecules the energy the cell can use to carry out its functions |
| endoplasmic reticulum | An organelle that forms a maze of passage ways in which proteins and other materials are carried from one part of the cell to another |
| Golgi apparaatus | An organelle in a cell that receives protein and other newly formed materials from the endoplasmic curriculum packages them and distributes them to other parts of the cell |
| vacuole | A saclike organelle, that stores, water, food, and other materials |
| chlorplast | Shin the cells of plants and some other organisms that capture energy from sunlight and changes it into any energy from the cells can use to make food |
| lysosome | Hey, so organelle which contains chemicals that breakdown large food particles into smaller ones, and that can be used by the rest of the cells |
| multicellular | Consisting of many cells |
| unicellurlar | Made of a single cell |
| tissue | A group of similar cells that perform a specific function |
| organ | A body structure that is composed of different kinds of tissue that work together |
| organ system | A group of organisms that work together, and perform major functions |
| element | A pure substance that cannot be broken down into other substances by chemical or physical means |
| compound | A substance made of two or more elements, chemically combined with a specific ratio or production |
| carbohydrate | And energy, rich organism, compounded, such as sugar or starch that made up of the elements, carbon, hydrogen and oxygen |
| lipid | And energy rich, organic compost, such as fat oil or wax that is made of carbon hydrogen and oxygen |
| protenin | Large organic molecule that is made up of carbon, hydrogen, oxygen nitrogen, and sometimes that sulfur |
| enzyme | A biological catalyst that lowers the activation of energy or reactions in the cell |
| nucleic acid | A very large organic molecule made up of carbon oxygen hydrogen nitrogen, and there’s a horse that contains the instructions cells need to carry out all the functions of life |
| DNA | Distributed acid is that genetic material that carries information about an organism and is passed from parent to offspring |
| double helix | The shape of a DNA molecule |
| selectively permeable | A property of cell membrane that allows some substance to pass across it while others cannot |
| passive transport | the movement of dissolved materials across a cell membrane without using cellular energy |
| diffusion | The process by which molecules move from an area of lower concentration |
| osmosis | The diffusion of water molecules across a selectively permeable membrane |
| active transport | The movement of materials across a cell membrane using cellular engery |
| endcytosis | The prosses by witch the cell membrane takes particles into the cell by changing shape and engulfing the particles |
| exocytosis | The process by which the vacuole surrounding particles fuses with cell membrane forcing the contents out of the cell |
