Exam 1 Flashcards
A cell that is itself an organism must have a minimum of four needs presented in lecture. List these four things.
food, shelter, to find a mate, and reproduce
A cancer cell will be anchorage-dependent for growth and immortal.
False
A normal cell is anchorage-dependent for growth and mortal.
True
A single-celled eukaryotic organism:
Has a limited number of biomolecular machines
Must find food, shelter, a mate and reproduce
Escape from predators
In your own multicellular body, different cells in your body have a division of labor between them.
True
The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney.
True
In order to examine cells which are smaller than can be detected by the human senses what needs to be used?
Technology
The paramecium swims by way of using a flagella.
False
What limits an individual cell from becoming more complex?
An individual cells has a limited number of biomolecular machines to use.
What limits the paramecium from acquiring more complex functions?
It has a limited number of bio molecular machines that it must utilize for basic functions, finding food, shelter, mate and reproduce and escape from predators.
Compared to bacteria which of the cell types are not responsible for finding food”
Lymphocyte, Macrophage, Fibroblast
Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself what is the major difference?
The Division of Labor
A cell that is anchorage-dependent for growth will also exhibit contact inhibition.
True
In Cell Biology what can limit the progress of science?
Technology
In your own multicellular body, cells with different functions have different DNA.
False
