  • Front
  • Back
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
Exocytosis
Engulfing large particles
Phagocytosis
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
Ecosystem
Organisms of the same species in an area
Population
Contraction of the cell contents due to the loss of water; Shrinking of cell
Plasmolysis
Bursting of a cell.
Cytolysis
Allows or Dissallows; certain substances can move accross the membraine while others cannot
Selectively Permeable Membraine
All populations in a particular area.
