Study Notes
Photosynthetic Organisms
- Algae, cyanobacteria, and plants are predominantly photosynthetic
Clade Viridiplantae
- The clade Viridiplantae is composed of land plants and green algae
Loss of Photosynthesis
- Some organisms, such as Indian pipe plant and Venus flytrap, have lost the genes for chlorophyll and photosynthesis
Historical Scope of Plant Kingdom
- According to Aristotle's biology, the plant kingdom historically included all organisms that were not animals
Photosynthesis
- Chlorophyll is the primary pigment used by plants in photosynthesis
Solubility
- Insolubility is the opposite property of solubility
Measuring Solubility
- The extent of solubility of a substance in a specific solvent is generally measured by the concentration of the saturated solution
Solubility Equilibrium
- Two substances are said to be at solubility equilibrium when the rate of dissolution equals the rate of precipitation
State of Solute
- The solute can be in a solid, liquid, or gaseous state
Dissolving in a Gas
- A solid or liquid can be 'dissolved' in a gas when it is in a state of vaporization or sublimation
