The Cell

107736541	Photosynthesis	The chemical process where plants use the sun's energy to produce sugars (food).
107736542	Cell Membrane	a thin, phospholipid bilayer, membrane around the cytoplasm of a cell that regulates what enters and exits the cell.

107736544	Nucleolus	structure inside the nucleus, where ribosomes are made.
107736545	Endoplasmic reticulum	a cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
107736546	Chloroplast	organelle found in some plant cells and certain unicellular organisms where photosynthesis takes place.
107736547	Selective permeability	a process in which a membrane allows some molecules to pass through while keeping others out.
107736548	Passive Transport	The movement of materials through a cell membrane without using energy.
107736549	Autotroph	an organism that makes its own food.
107736550	Cellular Respiration	the process by which cells use oxygen to produce energy from food.
107736551	Interphase	The stage of the cell cycle that takes place before cell division occurs; during this stage, the cell grows, copies its DNA, and prepares to divide.
107736552	Anaphase	The stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle (third step).
107736553	Cell	The basic unit of structure and function in living things.
107736554	Nucleus	The organelle that contains the DNA and controls the processes of the cell.
107736555	Organelle	Membrane bound structure inside a cell that performs a specific function.
107736556	Microtubule	Thin, hollow cylinders made of protein that provide structural support for eukaryotic cells.
107736557	Golgi Appartus	Organelle that packages and distrubutes molecules produced by the eurokaryotic cell.
107736558	Mitochondrion	An organelle that is the main site of energy conversion through cellular respiration.
107736559	Osmosis	Diffusion of water through a selectively permeable membrane from a high concentration to a low concentration.
107736560	Tissue	Group of similar cells that work together to do one job.
107736561	Heterotroph	Organism that obtains food by eating other organisms.
107736562	Anaerobic	Process that does not require oxygen.
107736563	Telophase	The final stage of mitosis or meiosis during which a nuclear membrane forms around each set of new chromosomes.
107736564	Cytokinesis	Division of the cytoplasm during cell division.
107736565	Cell Theory	States that all organisms are made up of one or more cells, the cell is the basic unit of life, and all cells come from other cells.
107736566	Cytoplasm	A jelly-like fluid inside the cell in which the organelles are suspended.
107736567	Chromatin	Long strands of DNA wrapped around proteins.
107736568	Microfilament	Solid rod of protein, thinner than a microtubule, that enables a cell to move or change shape.
107736569	Lysosome	A cell organelle that contains digestive enzymes.
107736570	Concentration	A measure of the amount of solute dissolved in a solvent.
107736571	Facilitated Diffusion	When substances transport across cell membranes using protein carrier molecules.
107736572	Organ	a collection of tissues that carry out a specialized function of the body.
107736573	Chlorophyll	green pigment in the ch that absorbs light energy used to carry out photosynthesis.
107736574	Aerobic	Process that requires oxygen.
107736575	Prophase	The first phase of mitosis. During prophase the replicated chromosomes condense, the spindle is formed, and the nuclear envelope breaks apart into vessicles.
107736576	Cell Wall	Strong outermost layer around the cell membrane of ONLY plants and some bacteria.
107736577	Prokaryote	A unicellular organism that lacks a nucleus and membrane bound organelles
107736578	Chromosome	A coiled structure in the nucleus that contains hereditary material.
107736579	Ribosome	A tiny structure in the cytoplasm of a cell where proteins are made.
107736580	Vacuole	A water-filled sac inside a cell that acts as a storage area.
107736581	Diffusion	Movement of particles from an area of high concentration to an area of lower concentration.
107736582	Active Transport	The movement of materials through a cell membrane using energy.
107736583	Organ System	A group of organs that work together in performing vital body functions.
107736585	Mitosis	The process of cell division in which the nucleus divides to form two identical nuclei.
107736586	Metaphase	The stage of mitosis and meiosis, during which all of the chromosomes move to the cell's equator.
