Zellbiologie Flashcards
cell wall
shape
protection
support
only by plants
made of cellulose
cell membrane
made of phospholipds
boundary (Grenze)
Mediator (Vermittler)
-> control, recognition, contact
cytosol
liquid in the cell
reservoir
site for chem reactions
nucleus
genetical informations (chromosomes)
control centre
nucleolus
in the nucleus
produces pre-ribosomes
chloroplast
photosynthesis
made of chlorophyll
only by plants
mitochondrion
cellular respiration
releases energy
ribosome
produces proteins
ER
produces lipids
transport of substances w vesicles
chem modification (Änderung) of substances
dyctosomes (golgi-apparatus
packs and repacks vesicles, modifies the content
produces carbohydrates
central vacuole
only by plants
for cellular pressure
stores reserves/ waste products
vesicles
memrane bubbles for transport of substances
centrosomes
poles for cell division
cytoskeleton
shape and resistance
for change in form
helps the transport
flagellum (Geissel)
cilia (Wimper)
moves the cell
e.g. sperm cell
