|
Solute |
Substance that dissolves in a solution |
|
|
Solvent |
Dissolving substance in a solution |
|
|
Exocytosis |
Many cells also released a large amount of materials a process known as this. During this the membrane of the vocuoles surrounding the material fuses with the cell membrane, forcing the contents out of the cell. The removal of Water by means of contractile vacuole is one example of this kind of active transport. |
|
|
Endocytosis |
Process of taking material into the cell by means of infoldings or pocketing of the cell membrane |
|
|
Hypertonic |
When comparing two solutions, the solution with the greater concentration of solutes |
|
|
Hypotonic |
When comparing two solutions, the solution with the lesser concentration of solute |
|
|
Mitochondria |
Cell organelle that converts chemical energy stored in food into compounds that are more convenient for the cell to use |
|
|
Phosopholipid |
A lipid containing a phosphate group and a molecule example lecithin. |
|
|
Facilitated Diffusion |
Process of diffusion in which molecules pass across the membrane through membrane channels |
|
|
Isotonic |
When the concentration of two solutions are the same |
|
|
Cristae |
Each of the partial portions in a mitochondrion formed by the infolding of the inner membrane |
|
|
Chloroplast |
Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy |
|
|
Microtublule |
A microscopic tubular structure present in the numbers of the cytoplasm of the cells, sometimes aggregating to form more complex structures |
|
|
Microphilament |
A small rod like structure oh, about four to seven nanometers in diameter, present in the numbers and the in the cytoplasm of many eukaryotic cells |
|
|
Osmosis |
Diffusion of water through a selectively permeable membrane |
|
|
Diffusion |
Process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated |
|
|
Selectively permeable |
Property of biological membranes that allows some substances to pass across it While others cannot: also called semi permeable membrane |
|
|
Aquaporin |
Water channel protein in a cell |
