Organization of Cells Flashcards
active transport
The movement of solutes against their concentration gradients using membrane transporters.
cancer
A tumor that spreads to other tissues; a malignant neoplasms
carcinogen
cancer causing substance
cytology
study of cells
cytoplasm
substance that fills the cells, consisting of liquid cytosol and organelles
diffusion
Movement of solutes from a region where they are in higher concentration to a region where they are in lower concentration
DNA
deoxyribonucleic acid
endocytosis
The movement of large amounts of material into a cell using vessels
exocytosis
The movement of large amounts of material out of the cell using vesicles
filtration
Movement of material through a semipermeable membrane down a pressure gradient.
gene
Hereditary factor; portion of the DNA on a chromosome encoding a specific protein.
hemolysis
disease of newborn (HDN). Condition that results from Rh incompatibility between a mother and her fetus; erythroblastosis fetalis
hypertonic
describing a solution that is more concentrated than the fluids within a cell
hypotonic
Describing a solution that is less concentrated then the fluids within a cell
interphase
Stage in a cell’s life cycle between one mitosis and the next; time period when a cell is not dividing.
isotonic
Describing a solution that has the same concentration as the fluid within a cell.
micrometer
1/1000th of a millimetre; an instrument for measuring through a microscope.
microscope
magnifying instrument used to examine cells and other structures not visible with the naked eye. compound light micro., transmission electron micro., and Scanning electron micro.,
mitochondria
cellular organelles that manufacture ATP with the energy released from the oxidation of nutrients; sing., mitochondrion.
mitosis
type of cell division that produces two daughter cells exactly like the parent cell.
