biology
| Question | Answer |
|---|---|
| Double-layered sheet that forms the core of nearly all cell membranes | Lipid Bilayer |
| Internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified | Endoplasmic Reticulum |
| Movement of specific molecules across cell membranes through protein channels | Facilitated Diffusion |
| Stack of membranes int he cell that modifies, sorts, and packages proteins from the endoplasmic reticulum | Golgi Apparatus |
| Process by which a cell releases large amounts of material | Exocytosis |
| Diffusion of water through a selectively permeable membrane | Osmosis |
| process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated | Diffusion |
| Material inside the cell membrane--not including the nucleus | Cytoplasm |
| Threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next | Chromozone |
| Cell organelle that stores materials such as water, salts, proteins, and carbohydrates | Vacuole |
| when the concentration of two solutions is the same. | Isotonic |
| The center of the atom which contains the protons and neutrons; in cells, structure that contains the cell's genetic material (DNA) and controls the cell's activities | Nucleus |
| Network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cellmovement | Cytoskeleton |
| When comparing two solutions, the solution with lesser concentration of solutes and a greater concentration of water | Hypotonic |
| process by which a cell takes material into the cell by infolding of the cell membrane | Endocytosis |
| thin, flexible barrier around a cell; regulates what entires and leaves the cell | Cell Membrane |
| Basic unit of all forms of life | Cell |
| When the concentration of a solute is the same throughout a solution | Equilibrium |
| Organism whose cells contain nuclei | Eukaryote |
| granular material visible within the nucleus; consists of DNA tightly coiled around proteins | Chromatin |
| energy-requiring process that moves material across a cell membrane against a concentration difference | Active Transport |
| Specialized structure that preforms important cellular functions within a eukaryotic cell | Organelle |
| the process in which cells develop in different ways to preform different tasks | Cell Specialization |
| small particle in the cell on which proteins are assembled; made of RNA and protein | Ribosome |
| small, dense regions within most nuclei in which the assembly or proteins | Nucleolus |
| when comparing two solutions, the solution with greater solution of solutes and the lesser concentration of water | Hypertonic |
| Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use | Mitochondrion |
| Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy | Chloroplast |
| one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope | Centrioles |
| Cell organelle filled with enzymes needed to break down certain materials in the cell | Lysosome |
| strong supporting layer around the cell membrane in plants algae and some bacteria | cell wall |
