Ch. 2 Science Flashcards
group of similar cells that work together to perform the same function
tissue
forms when a sperm cell and an egg cell join
zygote
substance formed by two or more elements that can be broken down into simpler substances
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
binary fission
stomach in the body
organ
result of uncontrolled cell growth and division is known as
cancer
substance that cannot be broken down into simpler subatances is called
element
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
process by which light energy is used to make sugars
photosynthesis
process that involves the movement of molecules through a cell membrane is known as
diffusion
type of sexual reproduction in microorganisms in which their cells attach to each other is called
conjugation
type of asexual reproduction in which an organism starts as a small growth on its parent is called
budding
this occurs when a mature male sex cell joins a mature female sex cell
fertilization
