What are the 3 major regions of a cell?
nucleus, cytoplasm, and plasma membrane
the movement of a substance from an area of its higher concentration to an area of its lower concentration
the movement of substances through a membrane from an area of high hydrostatic pressure to an area of lower hydrostatic pressure.
process by either diffusion or filtration
uses ATP (energy) provided by the cell
process in which particles are taken up by enclosure in a plasma membrane sac, includes phagocytosis
determines whether cells gain or lose water
a solution that contains more solutes than do cells. in these solutions cells lose water by osmosis and crenate.
a solution that contains fewer solutes than do cells. in these solutions, cells swell and may ruture as water rushes in by osmosis.
solutions that have the same solute to solvent ratio as cells. cause no change in cell size or shape.
begins after DNA has been replicated; it consists of four stages: prophase, mataphase, anaphase, and telophase. the result is two daughter nuclei, each identical to the mother nucleus
is the covering, lining, and glandular tissue. Its functions include protection, absorbtion, and secretion. Epithelia are named according to arrangement (simple, stratified) and cell shape (squamous, cuboidal, columnar)
is the supportive, protective, and binding tissue. it is characterized by the presence of a nonliving, extracellular matrix produced and secreted by the cells; it varies in amount and consistency. fat, ligaments, and tendons, bones and cartilage are all connective tissues
is composed of cells called neurons, which are highly specialized to receive and transmit nerve impulses and supporting cells. neurons are important in control of body processes. nervous tissue is lovated in nervous system structures- brain spinal cord and nerves
is specialized to contract, or shorten which causes movement. there are 3 types: skeletal (attached to the skeleton), cardiac (forms the heart), and smooth (in the walls of hollow organs)
wound healing. may involve regeneration, fibrosis, or both. in regerneration the injured tissue is replaced by the same type of cells. in fibrosis, the wound is repaired with scar tissue. Epithelia and connective tissues regenerate well. mature cardiac muscle and nervous tisse are repaired by fibrosis.
may be smooth or rough
is the diffusion of water across a selectively permeable membrane when some of the solutes cannot cross the membrane
involves the movement of solutes across a selectively permeable membrane by process of diffusion
active transport process
is the uphill movement of a substance through a living cell membrane
