Cell - The basic unit of all forms of life, Cell Membrane - regulates what goes into and out of the cell, Cell Theory - all living things are composed of cells, cells are the basic units of structure and function in living things and that new cells are produced from existing cells., Cell Wall - gives structure to plant cells, Chloroplast - site of photosynthesis in plant cells, Cytoplasm - fluid portion of the cell outside the nucleus that surrounds the organelles, Mitochondria - converts energy from food into energy a cell can use, Nucleus - contains genetic material (DNA) and controls the use of genes; found in eukaryotic cells, Organ - a group of tissues that perform a specific function or group of functions, Organ System - a group of organs that work together to perform a specific function or group of functions, Organelle - A membrane-enclosed structure with a specialized function within a cell., Tissue - a group of cells in an organism that have similar structure and function, Vacuole - the cell organelle that stores materials such as water, salts, proteins and carbohydrates, Eukaryote - A type of cell that has a membrane-enclosed nucleus and membrane-enclosed organelles., Prokaryote - A type of cell lacking a membrane-enclosed nucleus and other membrane-enclosed organelles, Lysosome - A digestive organelle in eukaryotic cells; contains hydrolytic enzymes that digest engulfed food or damaged organelles., Cytoskeleton - A network of protein fibers in the cytoplasm of a eukaryotic cell; includes microfilaments, intermediate filaments, and microtubules., Ribosome - a cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis, Golgi apparatus - an organelle in cells that modifies, sorts and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell, Lipid bilayer - a flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings, Osmosis - The diffusion of water across a selectively permeable membrane., Diffusion - The process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated, Facilitated diffusion - the process of diffusion in which molecules pass across the membrane through cell membrane channels, Osmotic pressure - the pressure that must be applied to prevent osmotic movement across a selectively permeable membrane, Homeostasis - The steady state of body functioning; a state of equilibrium characterized by a dynamic interplay between outside forces that tend to change an organism’s internal environment and the internal control mechanisms that oppose such changes.,
