The paramecium discussed in class contained an organelle called the contractile
vacuole. This is the presumed precursor of the: - ANSWER-kidney
A cell that is anchorage-dependent for growth will also exhibit contact inhibition.
- ANSWER-true
In your own multicellular body, cells with different functions have different DNA. -
ANSWER-false, their DNA is identical but different gene expression
The contractile vacuole of the paramecium is possibly an evolutionary precursor
of the kidney. - ANSWER-true
The paramecium swims by way of using a flagella. - ANSWER-false, they use cilia
In order to examine cells which are smaller than can be detected by the human
senses what needs to be used? - ANSWER-tehcnology
Compared to bacteria which of the cell types below are not responsible for
finding food - ANSWER-Lymphocyte
Macrophage
Fibroblast
A cancer cell will be anchorage-dependent for growth and immortal. - ANSWER-
false, a cancer cell is anchorage-independent for growth and immortal
A normal cell is anchorage-dependent for growth and mortal. - ANSWER-true
, A cell that is itself an organism must have a minimum of four needs presented in
lecture. List these four things. - ANSWER-a cell needs to find food, shelter,
reproduce, and mate. Also be able to escape predators.
In your own multicellular body, different cells in your body have a division of
labor between them - ANSWER-true
What limits the paramecium from acquiring more complex functions? - ANSWER-
the number of biomolecular machines it can contain within itself
Write a few sentences that explain what limits an individual cell from becoming
more complex. - ANSWER-It has a limited number of biomolecular machines that
a cell can contain and limits it from being more complex. It has to do everything
for itself. Also has a certain number of parts with which to change its
engineering, thereby changing its function.
In Cell Biology what can limit the progress of science? - ANSWER-technology
A single-celled eukaryotic organism: - ANSWER-Has a limited number of
biomolecular machines.
Must find food, shelter, a mate and reproduce
Escape from predators
Comparing a single-celled eukaryotic organism with a multicellular organism
such as yourself identify the major difference from the list below. - ANSWER-
Division of labor
We are made up of ....% water - ANSWER-50-70%
Explain how the vesicles are carried from the Golgi apparatus to the plasma
membrane. - ANSWER-Proteins are synthesized by ribosomes and enter the rER
(rough endoplasmic reticulum) . Vesicles bud off from the rER and carry proteins
to the Golgi.
The Golgi modifies proteins, and then the vesicles bud off from the Golgi and
carry modified proteins to the plasma membrane.
