SOS Biology Unit 3 Quiz 2
lysosomes
contain digestive enzymes
chromosomes
contain genes for traits
hypotonic
high concentration of water, low concentration of salt or saline
animal cell
no cell wall, only plasma membrane: no large vacuole, only small ones: no chlorophyll or chloroplasts: cleavage furrow plus centrioles in cell division:
plastids
store foods or pigments
endoplasmic reticulum
tubes serving as transportation channels
isotonic
when the concentration of two solutions is the same
semipermeable
membranes that allow some substances through but not others
mitochondria
A provider of energy for a cell. It breaks down glucose for energy.
meiosis
Cell division that produces reproductive cells in sexually reproducing organisms
osmosis
Diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal.
active transport
Molecules move from low concentration to high concentration builds higher concentrations
cell theory
basic unit of life is the cell
plant cell
cell plate and no centrioles in cell division: presence of cell wall plus plasma membrane: large hypertonic vacuole: chloroplasts and plastids:
5 transport mechanisms of a cell
facilitated diffusion passive diffusion active transport pinocytosis phagocytosis
centrioles
form fibers to separate chromosomes evenly
proteins
have polar and non polar ends of their membrane
plasma membrane
made of phospholipids
mitochondrion
production of needed energy
ribosome
production of protein
nucleolus
production of ribosomes
Golgi bodies
production of secretions
Glycosis creates
pyruvic acid
