Actin: Muscle protein making up the thin filaments in a sarcomere its movement shortens the sarcomere, yielding muscle contraction. Actin filaments play a role in the movement of the cell and its organelles.
Adenosine Triphosphate: Nucleotide with three phosphate groups.
Adhesion Junction: Junction between cells in which the adjacent plasma membranes do not touch but are held together by intercellular filaments attached to buttonlike thickenings.
Apoptosis: Programmed cell death involving a cascade of specific cellular events leading to death and destruction of the cell.
Capsule: Gelatinous layer surrounding the cells of bluegreen algae and certain bacteria.
Cell: Smallest unit that displays the properties of life composed of cytoplasm surrounded by a plasma membrane.
Cell Theory: One of the major theories of biology, which states that all organisms are made up of cells cells are capable of self reproduction and come only from preexisting cells.
Cell Wall: Structure that surrounds a plant, protist, fungal, or bacterial cell and maintains the cells shape and rigidity.
Cellular Respiration: Metabolic reactions that use the energy from carbohydrates, fatty acids, or amino acid breakdown, to produce ATP molecules.
Centriole: Cell organelle, existing in pairs, that occurs in the centrosome and may help organize a mitotic spindle for chromosome movement during animal cell division.
Centrosome: Central microtubule organizing center of cells. In animal cells, it contains two centrioles.
Cristae: Short, fingerlike projections formed by the folding of the inner membrane of mitochondria.
Cytoplasm: Contents of a cell between nucleus nucleiod region of bacteria and the plasma membrane.
Cytoskeleton: Internal framework of the cell, consisting of microtubules, actin filaments and intermediate filaments.
Endomembrane System: Collection of membranous structures involved in transport within the cell.
Endoplasmic Recticulum: System of membranous saccules and channels in the cytoplasm, often with attached ribosomes.
Eukaryotic Cell: Type of cell that has a membrane bounded nucleus and membranous organelles, found in organisms within the domain Eukarya.
Extracellular Matrix: Meshwork of polysaccharides and proteins that provides support for an animal cell and affects its behavior.
Fimbria: In bacteria, small bristle like fibers on bacterial cell surface that enable bacterial to adhere to surfaces.
Flagellum: Long, slender extension used for locomotion by some bacteria, protozoans, and sperm.
Gap Junction: Junction between cells formed by the joining of two adjacent plasma membranes it lends strength and allows ions, sugars, and small molecules to pass between cells.
Golgi Apparatus: Organelle consisting of saccules and vesicles that processes, packages, and distributes molecules about or from the cell.
Granum : Stack of chlorophyllcontaining thylakoids in a chloroplast.
Lysosome: Membrane bounded vesicle that contains hydrolytic enzymes for digesting macromolecules.
Matrix: Unstructured semifluid substance that fills the space between cells in connective tissues or inside organelles.
Microtubule: Small, cylindrical organelle composed of tubulin protein around an empty central core, present in the cytoplasm centrioles, cilia, and flagella.
Mitochondrion: Membrane bounded organelle in which ATP molecules are produced during the process of cellular respiration.
Nuclear Envelope: Double membrane that surrounds the nucleus in eukaryotic cells and is connected to the endoplasmic reticulum, has pores that allow substances to pass between the nucleus and the cytoplasm.
Nuclear Pore: Opening in the nuclear envelope hat permits the passage of proteins into the nucleus and ribosomal subunits out of the nucleus.
Nucleoid: Region of prokaryotic cells where DNA is located, it is not bounded by a nuclear envelope.
Nucleolus: Dark staining, spherical body in the nucleus that produces ribosomal subunits.
Nucleus: Membrane bounded organelle within a eukaryotic cell that contains chromosomes and controls the structure and function of the cell.
Organelle: Small, often membranous structure in the cytoplasm having a specific structure and function.
Sex Pilus: In bacterium, elongated, hollow appendage used to transfer DNA to other cells.
Smooth ER: Membranous system of tubules, vesicles, and sacs in eukaryotic cells lacks attached ribosomes.
Stroma: Fluid within a chloroplast that contains enzymes involved in the synthesis of carbohydrates during photosynthesis.
Surface Area To Volume Ratio: Ratio of a cell’s outside area to its internal volume.
Thylakoid: Flattened sac within a granum whose membrane contains chlorophyll and where the light reactions of photosynthesis occur.
Tight Junction: Junction between cells when adjacent plasma membrane proteins join to form an impermeable barrier.
Vacuole: Membrane bounded sac larger than a vesicle usually functions in storage and can contain a variety of substances. In plants, the center vacuole fills much of the interior of the cell.
Vesicle: Small, membrane bounded sac that stores substances within a cell.
