Maintenance of normal internal conditions in a cell or an organism by means of self-regulating mechanisms.
|
Homeostasis
|
|
Building while releasing water
|
Dehydration Synthesis
|
|
Breaking of large molecules into smaller molecules by adding water.
|
Hyrolosis
|
|
Contains DNA; has a nucleus and organelles
|
Eukaryotic organism
|
|
Contains DNA; no nucleus; have a cell membraine; has cell walls; has ribosomes
|
Prokaryotic
|
|
More solute-lower concentrate of water-than the cell (cause cells to shrink)
|
Hypertonic Solution
|
|
Lower concentration of solute-higher concentration of water-than inside the cell (causes cells to swell or even burst)
|
Hypotonic Solution
|
|
The solute concentration both inside & outside the cell are equal
|
Isotonic Solution
|
|
Type of molecue tat does not interact wit water because it is non-polar
|
Hydrophobic
|
|
Type of molecue that interacts with water by dissolving in water and/or by forming hydrogen bonds with water molecules
|
Hyerophilic
|
|
The diffusion of water
|
Osmosis
|
|
Movement of molecules from a region of higher concentration to a region of lower concentration
|
Diffusion
|
|
Process in which an intracellular vesicle fuses with the plasma membrane so that the vesicle's contents are released outside the cell
|

|
Engulfing of LIQUIDS or Dissolved Particles
|
Pinocytosis
|
|
All populations in a particular area.
|
Community
|
|
Biological community together with the associated abiotic environment; characterized by a flow of energy and a cycling of inorganic nutrients
