1. The paramecium discussed in class contained an organelle called the contrac-
tile vacuole. This is the presumed precursor of the:: kidney
2. A cell that is anchorage-dependent for growth will also exhibit contact inhibi-
tion.: true
3. In your own multicellular body, cells with different functions have different
DNA.: false, their DNA is identical but different gene expression
4. The contractile vacuole of the paramecium is possibly an evolutionary precur-
sor of the kidney.: true
5. The paramecium swims by way of using a flagella.: false, they use cilia
6. In order to examine cells which are smaller than can be detected by the
human senses what needs to be used?: tehcnology
7. Compared to bacteria which of the cell types below are not responsible for
finding food: Lymphocyte
Macrophage
Fibroblast
8. A cancer cell will be anchorage-dependent for growth and immortal.: false, a
cancer cell is anchorage-independent for growth and immortal
9. A normal cell is anchorage-dependent for growth and mortal.: true
10. A cell that is itself an organism must have a minimum of four needs present-
ed in lecture. List these four things.: a cell needs to find food, shelter, reproduce, and mate. Also be
able to escape predators.
11. In your own multicellular body, different cells in your body have a division of
labor between them: true
12. What limits the paramecium from acquiring more complex functions?: the
number of biomolecular machines it can contain within itself
13. Write a few sentences that explain what limits an individual cell from becom-
ing more complex.: 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.
14. In Cell Biology what can limit the progress of science?: technology

15. A single-celled eukaryotic organism:: Has a limited number of biomolecular machines.
Must find food, shelter, a mate and reproduce
Escape from predators
16. Comparing a single-celled eukaryotic organism with a multicellular organ-
ism such as yourself identify the major difference from the list below.: Division of
labor
17. We are made up of ....% water: 50-70%
18. Explain how the vesicles are carried from the Golgi apparatus to the plasma
membrane.: 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.
19. The plasma membrane gets new lipids from:: None of the above.
20. The ER is contiguous with the Golgi apparatus.: false
21. Explain the evolutionary origin of mitochondria.: It is thought that a primitive proto-eu-
karyote engulfed a primitive proto-prokaryote good at making ATP and this organism lived inside this larger cell and
began making ATP for the cell (endosymbiosis theory)
22. What is the difference between a triglyceride and a phospholipid?: Triglyceride
has 3 fatty acids attached to a glycerol backbone and a phospholipid has two fatty acids plus a phosphate group
attached to a glycerol backbone. One of the carbons from glycerol covalent links to the head group.
23. Amino acids can be largely subdivided into two groups. What are the two
groups?: polar/hydrophilic and nonpolar/hydrophobic
24. Facilitated diffusion uses a channel protein to let components move down
their concentration gradient.: true
25. If something is soluble in water a of hydration forms around it and it is
termed ...: hydrophillic
26. What are the two functions of a membrane?: To partition water and to compartmentalize
enzymes to increase efficiency of chemical reactions
27. Draw a phospholipid and make sure the numbers of carbons are clearly
identified.:
