Flashcards in Def Test Deck (33):
Movement of a liquid/gas through a semi-permeable membrane, from a high to a low concentration. This movement doesn’t require the input of energy / passive process.
The movement of water (liquid/vapor) from an area of high to an area of low concentration, through a semi-permeable membrane until equilibrium is achieved. Passive process.
The movement of a liquid/gas from a low to a high concentration, through a semi-permeable membrane. Energy is required.
The movement of a liquid/gas through a semi-permeable membrane, from a high to a low concentration with the aid of channels / proteins. Doesn’t require the input of energy / active process.
The type of force exhibited between molecules of the same substance.
Type of force exhibited between molecules of different substances.
The combination of cohesive and adhesive forces allowing a liquid substance to move (up) through a narrow tube.
Substance that dissolved in a solvent to form a solution.
Substance in which the solute dissolved to form a solution.
A homogeneous state in which a solute has fully dissolved in a solvent.
Refers to the (mineral / salt) solute concentration of a solution, when comparing two solutions across a semi-permeable membrane.
The solute concentration is lower compared to a solution on the other side of a semi-permeable membrane within a cell solution.
Water move via osmosis out the solution.
The solute concentration is higher compared to a solution on the other side of a semi-permeable membrane within a cell solution. Water move via osmosis into the solution.
Same solute concentration on either side of the semi-permeable membrane.
Monomer of a carbohydrate / polysaccharide
Carbohydrate / polymer of simple sugars.
Female plant gamete.
Female reproduction organ
Female animal gamete.
Phylum flowering plants
Transfer of pollen from anther to the stigma
Transfer of pollen between different plants of the same of different species
DNA / RNA molecule that comprises of nitrogenous bases bound to a sugar-phosphate backbone. DNA has deoxyribose sugar, RNA has a ribose sugar.
Process by which DNA molecule makes an exact copy of itself to prepare for replication. Replicated chromosomes are joined by a centromere.
Organelle that functions in protein synthesis.
Monomer if a nucleic acid compromising of a nitrogenous base, sugar and phosphate complex.
Enzyme that catalysts DNA replication
Plant life, occurring in an environment in which the new substrate is devoid of previous vegetation and other organisms, usually lacking soil.
The process of change in the species structure in an ecological community over time.
A process started by an event that reduces an already established ecosystem to a smaller population of species, meaning that this type of succession usually occurs on preexisting soil.
First species to establish in an area
Stage of ecological succession where the environmental is more stable, soil consists of nutrients. Generally characterized by shrub-type plants and medium-sized animals
