| Question | Answer |
| What is a cell? | Basic unit of all forms of life. |
| What is a cell theory? | Idea that all living things are composed of cells,cells are the basic unit of structure and function in living things, and new cells are produced from existing cells. |
| What is a nucleus? | In cells stucture that contain s the cell's genetic material and controls the cll's activities. |
| What is a eukaryote? | Organism whose cells contian nuclei. |
| What is a prokaryote? | Unicellular organism lacking a nucleus. |
| What is a organelle? | Specialled structures that performs important cellular functions within a eukaryotic cell |
| What is a cytoplasm? | Material inside the cell membrane- not including the nucleus. |
| What is a nuclearar envelope? | Layers of two membranes that surrounds the nucleus of a cell. |
| What is a chromatin? | Granular material visible within the nucleus. |
| What is a chromosome? | Threadlike struvture within the nucleus containing the genetic information that passed from one generation of the cells to the nexts. |
| What is a nucleolus? | Small,dense region within most nuclei in which the assembly of protien begins. |
| What is a ribosome? | Small particles in the cells in which protiens are assembled; made of RNA and protien. |
| What is a endoplasmic reticulum? | Internal membrane system in cells in which lipid components of the cell membrane are assembled and protiens are modified. |
| What is Golgi apparatus? | Stacks of membranes in the cells that modifies, sorts, and packages protiens from the endoplasmic reticulum. |
| What is a lysosome? | Cell organelle filled with enzymes needed to break down certian materials in the cells. |
| What is a vacuole? | Cell organelle that stores material such as water, salts, protiens, carbohtdrates. |
| What is a mitochondrion? | Cell organelle that cinverts to chemical energy stored in food into compounds that are more convenient for the cell to use. |
| What is a Chloroplast? | Organelle found in cells of plants and some other organism that captures the energy from the sun light and converts into chemical energy. |
| What is a cytoskeleton? | Network of protien filaments within some cells that helps the cells maintianits shape aand is invoild with many forms of cell movemoent. |
| What is centriole? | One of two tiny structures located in the cytoplasm of animal cells near the nuclear envepole. |
| What is cell membrane | Thin, flexible barrier around a cell; regulates what enters and leaves the cell. |
| What is cell wall? | Strong supporting layer around the cell membrane in plants, algea, and some bacteria. |
| What is a lipid bilayer? | Double-layered sheet that form the core of nearly all cell membranes. |
| What is concentration? | The mass os the solute in a given volume of solution, or mass/volume. |
| What is diffusion? | Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated. |
| What is equilibrium? | When the concentration of a solute is the same throughout a solution. |
| What is a osmosis? | Diffusion of water through a selectively permeable membrane |
| What is isotonic? | When the concentration of two solutions is the same. |
| What is hypertonic? | When comparing two solutions, the solutionwith lesser concentration of solutes. |
| What is facilitated diffusion? | Movement of specific molecules across cell membrane through protien channels |
| What is active transport? | Energy-requiring process that moves material across a cell membrane againts a concentration difference |
| What is endocytosis? | A process by which a cell takes material into the cell by infolding of the cell membrane. |
| What is phagocytosis? | A process in which extension of cytoplasm surround and engulf large particles and take them into a cell. |
| What is pinocytosis? | A process by which a cell takes in liquid from the surrounding environment. |
| What is exocytosis? | A process by which a cell releases large amounts of material. |
| What is cell specialization? | Cells throughout an organism can develop in differnet ways to perform different tasks. |
| What is tissue? | Is a group of similar cells that perform a particular function. |
| What is organ? | Many groups of tissue that work together. |
| What is organ system? | A group of organs that work together to perform a specific function. |
