Biologie voor jou Havo 4 Thema 1 Paragraaf 1.3 en 1.4 en 1.5 Functie = schuingedrukt

Celwand Cellulose
Stevigheid

Plant Cel Celmembraan Dubbele laag fosfolipiden (vetachtig) met daartussen eiwitmoleculen Transport stoffen in en uit cel
Scheiding met buiten (membraaneiwitten)

Cytoplasma Water
Inwendige van de cel
Plastiden Bladgroenkorrels (Chloroplasten) Groenekleurstoffen (fotosynthese)
Kleurstofkorrels (Chromoplasten) Geel, oranje, roodkleurstoffen
Leukoplasten Opslag vet, zetmeel en eiwit

Opgeloste stoffen

Celkern Kernmembraan
Kernplasma Chromosomen (lange moleculen DNA)

Vacuole Vocht Stevigheid
Vacuolemembraan
Kleurstoffen (soms)

Membranen Endoplasmatisch reticulum (ER) Ruw RER (Ribosomen: productie eiwit ) Eiwitsynthese
Glad GER Stofwisseling cel
(productie vetten/afbreken gifstoffen)

Ribosomen in het cytoplasma en in een RER Productie eiwitten

Mitochondrien
Verbranding glucose in cel, met energie daarvan vormen mitochondrien de stof ATP, ATP wordt gebruikt als er energie nodig is in de cel.

Ruimte tussen cellen = intercellulaire ruimten = gevuld met lucht of vocht

Organel = deel van een cel met eigen functie Celkern:

Trilharen = voorbeweging van de cel of verplaatsing stoffen langs de cel




Endoplasmatisch reticulum = netwerk van membranen (afgeplatte holten en kanaaltjes), verbonden met celmembraan (ruw en glad)
