Nematocyst – a cell which contains stinging barbs or toxins; found only in cnidarians such as the jellyfish
hydrocarbon – An organic molecule consisting of only carbon and hydrogen.
Solute – Substance that is dissolved in a solvent to make a solution; Example: Salt
ion – atom that has gained or lost one or more electrons.
isotonic solution – A solution that contains the same concentration as the solution on the other side of a cell wall.
Multicellular organisms – Are all eukaryotic- though some single celled organisms -Kingdom Protista-are eukaryotic
photosystems – molecules that capture and transfer energy from light
organ – A collection of tissues that carry out a specialized function of the body.
cell – basic unit of structure and function in living things
This structure is the outmost structure that supports the testes.
transcription – process in which a strand of mRNA is built using the genetic information found on a strand of DNA
signal transduction pathway – In cell biology, a series of molecular changes that converts a signal on a target cell's surface to a specific response inside the cell.
endocytosis – A process in which a cell engulfs extracellular material through an inward folding of its plasma membrane.
genotype – an organism's allele pairs
DNA – genetic material that carries inherited information to code for proteins
Abiotic – a non-living thing; does not have all the characteristics of life
This structure is the оutmоst structure thаt suppоrts the testes.
Hypertonic solution – A solution having a higher concentration of solute than inside a cell, which shrinks or shrivels when water leaves the cell by osmosis.
Catalyst – substance that lowers activation energy needed to start a chemical reaction
