Answer 4

limited by ability to pack structural components into the cell

Question 5

size of cell: maximum size

Answer 5

limited by ratio of sa to volume

Question 6

to increase SA…

Answer 6

branching and folding

Question 7

membranes (sheet like structure)- functions

Answer 7

1. compartmentalization
2. semi-permeable (selective passage of material)
3. sites of chemical reactions

4.receptors for cell recognition
(injury response)
