, Definities
SYSTEMATIEK
Systematiek = ordenen van organismen volgens bepaalde criteria
Taxon = groep organismen die in de systematiek wordt erkend en die een naam heeft
Classificatie = overzicht van de taxa die in de systematiek worden erkend
Nomenclatuur = reglementering die het toekennen van namen regelt
Fenetische systematiek = gebaseerd op mate v gelijkenis
Fylogenetische systematiek = gemeenschappelijke voorouder
Plesiomorfie = alles wat ze geerfd hebben
Apomorfie = kenm waarmee ze verschillen vd voorouders
Autapomorfiën = kenm uniek bij taxon als het het laagste analyseniveau is vr dat kenm
Synapomorfie = ze hebben het omdat het ontstaan is uit de meest recente voorouder
Monofyletisch taxon = taxon dat alle nakomelingen bevat ve gem. voorouder
Homologie = hetzelfde orgaan in verschillende dieren in elke variatie van vorm en functie
Analoog = niet vd zelfde voorouder
Homoplasie = ik denk dat het homoloog is (remane), maar men Fylogenetische analyse zegt
van niet
Polyfyletisch taxon = Samengesteld uit versch. takken (convergenties/parralellisme)




Parafyletische taxa = delen synapomorfiën id groep niet (overblijvende groep dr ontbreken v
synapomorfie)




EMBRIOLOGIE
Ectoderm= laag waar later het epidermis gaat gevormd w
Animale pool = kant vd kern (AP)
Vegetatieve pool = kant vd dooier (VP)
Dexiotroop = naar rechts gericht
Leiotroop = naar links gericht
Gastrulatie = proces v op plaats brengen v endoderm
Blastoporus = opening
Archenteron = rest vd holte
Alecith = zonder dooier (lecith = met dooier)
Prolifereren= heel sterk delen
Multipolaire = heel epitheel deelt
Unipolair = een stukje vh het epitheel deelt
