100
The basic unit of life.
What is a cell?
100
diffusion of water molecules across a semi-permeable membrane from an area of high to low concentration.
What is Osmosis?
100
Movement of materials in & out of the cell.
What is cellular transport?
100
an organism's ability to keep an internal equalibrium in responce to changes in the environment.
What is homeostasis?
100
gel-like substance which fills the cell.
What is Cytoplasm?
200
Transmits messages
What is a nerve cell?
200
same concentration of water & solutes
What is Isotonic?
200
doesn't require any energy from the cell.
What is Passive Transport?
200
it gets rid of change.
What is negative feedback?
200
where enzymes are made.
What is Ribosomes?
300
stretch and contract, causing body movements
What is a muscle cell?
300
less concentration of solute.
What is Hypotonic?
300
does require energy from the cell.
What is active transport?
300
increases responce (emergency only)
What is positive feedback?
300
contains DNA.
What is a Nucleus?
400
Special receptors that can detect cold and heat
What is a nerve cell in skin?
400
More solutes, less water.
What is hypertonic?
400
movement of a group of particles from where there's lots of them to an area where there's not so much of them.
What is diffusion?
400
vary from organism to organism, but often involve hormonal signal.
What is process & control involved in homeostasis?
400
rigid "square" structure found in plant cells, bacteria, and fungi that aids support.
What is a cell wall?
500
the nerve cell in the that transmit, receive, and interrupt messages.
What is a Brain Cell?
500
means to pull in Greek.
What is tonic?
500
Eating solids.
What is phagocytosis?
500
receptor is the sensing component that monitors and responds to changes in the environment
What is Control mechanisms?
500
area of storage for food, water, and waste.
What is a Vacuole?
