cell theory
The theory that all living things are composed of cells and all cells come from other cells. |

|
chromosome
A threadlike, gene-carrying structure found in the nucleus. Each chromosome consists of one very long DNA molecule and associated proteins. See chromatin. |
chromosome
|
|
basal body
A eukaryotic cell organelle consisting of a 9 + 0 arrangement of microtubule triplets; may organize the microtubule assembly of a cilium or flagellum; structurally identical to a centriole. |
basal body
|
|
dynein arms
A protein extension from a microtubule doublet in a cilium or flagellum; involved in energy conversions that drive the bending of cilia and flagella. |
dynein arms
|
|
extracellular matrix
(ECM)The substance in which animal tissue cells are embedded consisting of protein and polysaccharides. |
extracellular matrix
|
|
granum
(plural, grana) A stacked portion of the thylakoid membrane in the chloroplast. Grana function in the light reactions of photosynthesis. |

glycoprotein
A protein covalently attached to a carbohydrate |
glycoprotein
|
|
endomembrane system
The collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles. |
endomembrane system
|
|
anchoring junctions
Adhesive junctions that link cells together into tissues. |
anchoring junctions
|
|
intermembrane space
One of the fluid-filled compartments in the mitchondrion. |

|
|
lysosomal storage disease
A hereditary disorder associated with abnormal lysosomes, where the sufferer is missing one of the lysosomal digestive enzymes. |

|
|
mitochondrial matrix
The compartment of the mitochondrion enclosed by the inner membrane and containing enzymes and substrates for the Krebs cycle. |
mitochondrial matrix
|
|
nucleoid region
The region in a prokaryotic cell consisting of a concentrated mass of DNA. |

|
|
microtubule
A hollow rod of tubulin protein in the cytoplasm of all eukaryotic cells and in cilia, flagella, and the cytoskeleton. |

|
|
prokaryotic cell wall
A fairly rigid, chemically complex structure that exists outside the plasma membrane of most prokaryotes. |
prokaryotic cell wall
|
|
pilus
(plural, pili) A surface appendage in certain bacteria that functions in adherence and the transfer of DNA during conjugation. |
pilus
|
|
prokaryotic flagellum
A long surface projection that propels a prokaryotic cell through its liquid environment; totally different from the flagellum of a eukaryotic cell |
prokaryotic flagellum
|
|
(plural, plasmodesmata) An open channel in the cell wall of plants through which strands of cytosol connect from adjacent cells.
|
plasmodesma
|
|
tight junction
A type of intercellular junction in animal cells that prevents the leakage of material between cells. |
tight junction
|
|
transport vesicle
A tiny membranous sac in a cell's cytoplasm carrying molecules produced by the cell. |
transport vesicle

|
secretory protein
Proteins that are secreted by the cell via the endoplasmic reticulum. |
secretory protein
|
|
A sticky layer that surrounds the cell walls of some bacteria, protecting the cell surface and sometimes helping to glue the cell to surfaces
