| collection of living matter enclosed by a barrier that separates it from its surroundings; basic unit of all forms of life | ||
| structure containing DNA and RNA and controls the cell's activities | ||
| all living things composed of cells, cells are the basic units of structure and function in living things, new cells produced from existing cells | ||
| an organism whose cells contain neclei | ||
| single-celled organisms that lack a nucleus | ||
| structure inside eukaryotic cells that performs specialized functions. | ||
| material inside the cell membrane, but not including the nucleus | ||
| layer of two membranes that surrounds the nucleus of a cell | ||
| material visible within the nucleus, consists of DNA tightly coiled around proteins | ||
| threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next | ||
| small dense region within most nuclei in which the assembly of ribosomes begins | ||
| small particle in the cell on which proteins are assembled, made of RNA and protein. | ||
| internal membrane system in cells in which lipid components are assembled and some proteins are modified | ||
| stack of membranes that modifies, sorts, and packages proteins from the endoplasmic reticulum and sends proteins to their final destination | ||
| cell organelle that breaks down wastes using enzymes | ||
| cellorganelle that serves as a storage container for water and other liquids | ||
| cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use | ||
| organelle found only in plant cells, converts light energy to in chemical energy through photosynthesis | ||
| a network of protein filaments that holds the cell together, helps the cell to keep its shape, and aids in movement | ||
| located in the cytoplasm of animal cells - aids in reproduction - near nuclear envelope | ||
| thin, flexible barrier around a cell, regulates what enters and leaves the cell | ||
| strong supporting layer around the cell membrane in plants, algae, and some bacteria | ||
| double-layered sheet that forms the core of nearly all cell membranes | ||
| mass/volume | ||
| movement of particles from an area of high concentration to an area of lower concentration | ||
| when the concentration of a solute is the same throughout the solution | ||
| The diffusion of water across a selectively permeable membrane. | ||
| when the concentration of 2 solutions is the same | ||
| solution with the greater concentration | ||
| solution with the lesser concentration | ||
| movement of specific molecules across cell membranes through protein channels | ||
| energy requiring process that moves materials across a cell membrane against a concentration difference | ||
| process of taking material into the cell by means of infoldings, or pockets, of the cell membrane | ||
| process by which a cell releases large amounts of material | ||
| cell eating- extensions of cytoplasm surround and engulf large particles and take them into the cell | ||
| "cellular drinking" - cell takes droplets of fluid from surroundings | ||
| group of similar cells that perform a particular function | ||
| group of tissues that work together to preform closley related functions | ||
| group of organs that work together to perform a specific function | ||
| cells throughout an organism can develop in different ways to perform different tasks |
