Mitosis Importance
Mitosis is important to multicellular organisms because to grow, cells need to reproduce. It is important for single-celled organisms like ameobas and paramecium to reproduce to keep their species alive.
Homeostasis
A balance or equilibrium
Solvent
A liquid substance (usually water) used to dissolve the solute
Solute
The dissolved substance in a solution
Solution
A mixture of a solvent and a solute
Osmotic Equilibrium
The state in which there is an even concentration of water molecules inside the cell and outside the cell, so that molecules move in and out of the cell at the same rate and the cell does not shrink or swell
Cell Membrane
A thin membrane around the cytoplasm of a cell made up of two layers of phospholipids with proteins embedded in them that controls the passage of substances in and out of the cell. A cell membrane is semipermeable, meaning it only lets certain substances pass through.
