cell structure Flashcards
1
Q
cell theory
A
- basic structural unit of all living organisms
- new cells are produced from pre existing cells
2
Q
prokaryote cell
A
- small and simple
- bacteria
features - cell wall
- plasma membrane
- fagella
- pili
- ribosomes
- nucleoid
no nucleous and membrane enclosed organells
3
Q
eukaryote cell
A
-more coplex
- membrane bound organells
4
Q
nucleus
A
- ribosomes reproduction
- large
- double membrane
- all eukaryotic cells
5
Q
edoplasmic reticulum
A
- covered in ribosomes
- plant and animal
- processes protein
roughER - protein developemnt and tranport
smoohER
- detoxitiates drugs in the liver
transports liquid based compunds
6
Q
ribosomes
A
- site of translation
- made of ribosomal RNA and protein
- freely in cytoplasm
7

mitochondria
A
- aerobic respiration
- double membrane
8
Q
golgi apperatus
A
- modifies protein and lipids
9
Q
vesicle
A
membrane bound sac which transports and storages
10
Q
lysosome
A
- contains hydrolytic enzymes
- breaks down waste materials
- used by the immune system
11
Q
chloroplast
A
- plant cells
- surrounded by a double membrane
- photosynthesis
12
Q
vacule
A
- in plant cells (sometimes in animal but small)
- used for storage
13

cell wall
A
plant cell only
structural support
