cell intro Flashcards
1
Q
3 basic features of cell
A
- compartmentalization (division)
-allows for specialization
-self assembly and hoeostasis
becuase they have all materials they need
- replication
-every cell is formed from a pre-existing cell
2
Q
eukaryotic
A
organelles surrounded by a membrane
3
Q
prokaryotic
A
no organelles surrounded by membranes
-since small, dont need to be divided.
4
Q
size of cell:
minimum size
A
limited by ability to pack structural components into the cell
5
Q
size of cell: maximum size
A
limited by ratio of sa to volume
6
Q
to increase SA…
A
branching and folding
7
Q
membranes (sheet like structure)- functions
A
- compartmentalization
- semi-permeable (selective passage of material)
- sites of chemical reactions
