compound
process that occurs in mitochondria in which molecules are converted into energy is known as
cellular respiration
type of asexual reproduction in which an organism divides into two is called

stomach in the body
organ
result of uncontrolled cell growth and division is known as

cell surrounded by a cell wall that carries genetic information
spore
process that produces two cells, each with a full set of chromosomes
mitosis
smallest part of an organism that can carry out life functions
cell
water molecules move through membranes without the use of the cell’s energy as a result of
osmosis
molecules move through cell membranes without the use of the cell’s energy results in
passive transport
molecules move through cell membranes with the use of the cell’s energy as a result of
active transport
process that produces four cells, each with only half as many chromosomes as four original cell is known as
meiosis
