T/F the cytoskeleton gave rise to the nuclear envelope ✔Correct Answer--false
What limits how big a cell can be? ✔Correct Answer--the surface area to volume ratio
T/F DNA in extant prokaryotic cells is circular. ✔Correct Answer--True
Why did Motility improved the fitness of these early cells? ✔Correct Answer--it allowed them to
move away from predators and towards food
T./F the end of the retraction fiber touching the cell culture plate still contains the cell equivalent of
super glue. ✔Correct Answer--true
, T/F the presumed first step in the transition of the primitive, proto-prokaryotic cell into the primitive,
proto-eukaryotic cell was the loss of the cell wall. ✔Correct Answer--true

to be used ? ✔Correct Answer--technology
A cell that is itself an organism must have a minimum of four needs presented in lecture ✔Correct
Answer--find food, find shelter, find mate, and reproduce.
compared to bacteria which of the cell types below are not responsible for finding food? ✔Correct
Answer--lymphocyte, macrophage, and fibroblast
T/F In your own mulitcellular body, different cells in your body have a division of labor between
them. ✔Correct Answer--true
T/F The paramecium swims by way of using a flagella ✔Correct Answer--false
T/F A normal cell is anchorage-dependent for growth and mortal ✔Correct Answer--true
what limits the paramecium from acquiring more complex functions? ✔Correct Answer--cannot fit

cell have a limit number of biomolecular machines. In a multicellular organism you get a division of
labor between different cell types so that the whole can do more than the sum of the parts with
similar number of biomolecular machines per cell.
