The study of living things
biology
An experiment is designed to test a
hypothesis
proteins are formed from monomers (subunits) called
Nucleic acid
The powerhouse of the cell is the
mitochondria
The organelle found only in plants; captures sun's energy during photosynthesis is
chloroplast
A problem-solving model is the
Scientific method
the basic unit of structure and function in living things is the
cell
the process by which bacteria reproduce is called
binary fission
the storage bin of a cell is the
vacuole
the substance that gives an object color is
pigment
a hypothesis must be
testable
The outermost structure of an animal cell is the
cell membrane
Antibiotics only work on
bacteria
the outer layer that controls what comes in and out of a cell is the
Cell membrane
Substances that kill harmful bacteria are _______
antibiotics
after scientists make a hypothesis, they perform a(n)
experiment
The cellular process that converts solar energy into chemical energy is
photosynthesis
A group of ORGANS work together to perform a specific job is
Organ system
The ability of an organism to keep conditions inside its body constant is
homeostastis
Diffusion of water through a membrane is
osmosis
An idea that has been tested by scientist over a period of
time is
theory
An animal cell surrounded by fresh water will burst because the osmotic pressure causes water to
move into cell
Makes up the largest part of the cell
cytoplasm
The control center of the cell is the
nucleus
Chromosomes contain
chromatin
