Organisms whose cells never contain a nucleus
The concentration of solutes inside the cell is greater than the concentration of solutes outside the cell
A process where a cell engulfs a food particle instead of a drop of liquid
Proteins are made by this
Structures that work like miniature organs, carrying out specific functions in the cell
The Cell's Cytoplasm
Everything between the cell membrane and the nucleus
Sometimes called cell drinking
The net movement of molecules from an area of higher concentration to an area of lower concentration
The difference between the concentration of a particular molecule in one area and the concentration in an adjacent area
Makes ribosomes, which, in turn, builds proteins
Only allows certain molecules to pass through
The "power-house" of a cell
Poisons, wastes, and other toxic chemicals are made harmless in this. It also connects the nuclear envelope to the cell membrane
In the nucleus contsin coded "blueprints" that control all cellular activity
Are short, hairlike projections for locomotion
Maintains a three- dimension structure of the cell and helps the cell move
The diffusion of water across a semipermeable membrane
When energy is used to transport molecule across the membrane
Suspended In The Cytosol
Are tiny organelles
The concentration of solutes inside and outside the cell is equal
Are hollow tubes, like plumbing pipes that maintain the shape of the cell and serve as tracks for organelle sto move along within the cell
The concentration of solutes outside the cell is higher than the concentration of solutes inside the cell
