, Terminologie
Wetenschappelijke naam van voorbeelden hoef je niet te kennen
Wel bij elke eigenschap een voorbeeld kennen

 Morfologie: de uitwendige studie van de organen
 Anatomie: orgaanleer (de studie van de inwendige schikking en
aanwezigheid van weefseltypes en celtypes)
 Histologie: weefselleer
 Cytologie: cellenleer
 Homologe structuren: structuren die oorspronkelijk hetzelfde bouwplan
en dezelfde functie hadden, maar andere functies en vormen gekregen
hebben en er dus ook anders uitzien
 een bloemblaadje is homoloog aan een groen loofblad
 Analoge structuren: structuren die een gelijkende/dezelfde functie
hebben en daardoor op elkaar gelijken, maar evolutionair afzonderlijk tot
stand zijn gekomen
 Convergente evolutie: de ontwikkeling van dezelfde eigenschap bij
verschillende, niet duidelijk met elkaar verwante taxonomische groepen
 leid tot analoge structuren
 Radicula: de primaire wortel van de kiemplant
 Adventiefwortels: de bijwortels van een plant met als functie
