| Question | Answer |
|---|---|
| What is the basic building block of life? | Cell |
| This states: -All living things are composed of cells -Cells are the basic units of structure and function -New cells are produced from existing cells | Cell Theory |
| What contains the cell's genetic info? | Nucleus |
| Cells with a nucleus are called what? | Eukaryote |
| Cells without a nucleus are called what? | Prokaryote |
| What are the organs of cells called? | Organelle |
| What is the portion of the cell outside the nucleus? | Cytoplasm |
| What is the membrane surrounding the nucleus called? | Nuclear Envelope |
| What is DNA bound to protein called? | Chromatin |
| What is condensed chromatin? | Chromosome |
| What is the center of a nucleus called? | Nucleolus |
| Small particles of RNA that assemble proteins are called? | Ribosome |
| Where are lipids, proteins, and other materials assembled? | Endoplasmic Reticulum |
| What organelle modifies, sorts, and packages proteins? | Golgi Apparatus |
| What organelle cleans up "junk" from the cell? | Lysosome |
| What organelle acts as a storage area? | Vacuole |
| What organelle convert chemical food energy into cell energy? | Mitochondrion |
| What organelle turns sunlight into energy through photosynthesis? | Chloroplast |
| What is a network of protein filaments that helps cells maintain shape? | Cytoskeleton |
| What helps organize cell division? | Centriole |
| What is the thin barrier protecting a cell called? | Cell Membrane |
| What is a strong membrane surrounding the cell called? | Cell Wall |
| What are cell membranes composed of? | Lipid Bilayer |
| What is the mass of solute in a given volume? | Concentration |
| What is the movement of particles from high to low? | Diffusion |
| When the concentration of a solute is equal through and through, this is called what? | Equilibrium |
| What is the diffusion of water through a selectively permeable membrane called? | Osmosis |
| Two solutions with the same strength are? | Isotonic |
| A solution with concentrated strength is? | Hypertonic |
| A solution with diluted strength is? | Hypotonic |
| When cell membranes factilate glucose across them, this is called what? | Facilated Diffusion |
| When particles are needed to be moved from low to high, this occurs. | Active Transport |
| What is the process of taking material into the cell via pocketing or folding of the membrane? | Endocytosis |
| What occurs when extensions of cytoplasm surround a particle and package it in a food vacuole? | Phagocytosis |
| What is the process in which pockets of liquid in the membrane fill up and becone vacuoles? | Pinocytosis |
| What is the process in which a vacuole fuses with the cell membrane to excrete waste? | Exocytosis |
| What is the process in which cells throughout an organism can develop in different ways to perform different tasks? | Cell Specialization |
| What is a group of similar cells called? | Tissue |
| When tissues group together to work together, a what results? | Organ |
| When groups of organs work toether, what do you get? | Organ System |
