most basic unit of life

a type of cell with a nucleus enclosed by a membrane as well as membrane-enclosed organelles

a type of cell that is simple in structure and lacks a membrane-enclosed nucleus and membrane-enclosed organelles; they have an outer cell wall that gives them shape

the theory that (1) all organisms are made out of one or more cells; (2) cells are the smallest units of life; (3) cells come from pre-existing cells via cell division

one of many membrane-enclosed structures that are found in the cytosol of eukaryotic cells, each with its own specific function

an organelle in eukaryotic cells that contains the cell's chromosomes

an organelle in eukaryotic cells that is the site of cellular respiration and generates most of the cell's ATP

a network of protein fibers found in eukaryotic cells

molecular structure that facilitates DNA translation into protein

a biological membrane, also called the plasma membrane, that surrounds a cell and selectively controls which substances can enter or leave the cell

an organelle in plant and algae cells that converts energy from sunlight into chemical energy that the plant can use

the fluid part of a cell

property of a membrane to allow passage of specific molecules

movement of ions or molecules across a membrane, often against a concentration gradient; requires energy input; endocytosis is an example

movement of ions or molecules across a membrane down a concentration gradient ; it does not require the input of energy

the diffusion of water through a selectively permeable membrane towards the side of the membrane with a higher solute concentration

dispersion of substances in a gas or liquid
