Jeopardy—Biology
The Cell
Rules:
- answers do not have to be in question form
- each correct answer is worth one point
- each incorrect answer takes a point away
- if an answer is given out of turn, that team loses a point and all other groups are
given a point
1. Does a cell becomes more efficient or less efficient at life processes as it gets
larger?
less efficient
2. Name the type of cell that has no membrane-bound nucleus and no
organelles.
prokaryote
3. What are the two main components that make up the cell membrane?
phospholipids and proteins
4. What is the name for the 2 layers of phospholipids in the cell membrane?
lipid bilayer
5. The polar head groups of phospholipids face towards the outside of the cell
and the inside of the cell because they are___________________?
hydrophilic (water-loving)
6. The fatty acid tails of phospholipids orient themselves towards the inside of
the cell membrane because they are__________________?
hydrophobic (water-fearing)
7. Name a function of the golgi apparatus.
process (or modify) proteins, package proteins for transport outside cell
8. Name two organelles present in plant cells but not in animal cells.
cell wall, chloroplasts, large central vacuole
9. The cell membrane lets some things into cell and not other things. This
property means that the cell membrane is_______________________.
selectively permeable
10. Name two substances that are able to get through the lipids of the cell
membrane.
CO2 and O2
11. Name a type of protein found in the cell membrane.
marker protein, receptor protein, channel (or transport) protein
12. Name two substances that can’t get directly through the lipids and have to
use a channel protein.
water, ions, any charged substance
13. Muscle cells need lots of energy, so they have lots of this organelle.
mitochondria
14. In a eukaryotic cell, DNA is found in the _________________.
nucleus
15. Who was the first person to see dead cells (cork) under a microscope?
Robert Hooke
16. List the 3 parts of the cell theory.
- all living things are made of cells
- the cell is the most basic unit of life
- cells only come from other cells
17. Draw the structure of the lipid bilayer.
18. Who was the first person to see living cells under the microscope and is
known as the Father of the Microscope?
Anton Van Leeuwenhoek
19. Name a cell that is not microscopic.
chicken egg, human egg, some nerve cells(neurons)
20. Does a cell’s structure (what it looks like) have anything to do with its
function (what it does)?
yes, what a cell looks like (shape, size, etc) is related to what it does.
21. What is the average size of a bacterial cell in microns?
1 micron
22. Which is larger in general, an animal cell or a plant cell?
plant cell (30 to 50 microns). Animal cells are smaller at 10 to 30 microns.
23. As a cell gets larger, the surface area to volume ratio decreases, meaning
that the ____________ increases at a slower rate than the ______________.
surface area, volume
24. Name the cell that has a membrane-bound nucleus and organelles.
eukaryote
25. Explain how an organelle of a cell is like an organ in your body?
Just like every organ does a specific job to keep the body alive, every organelle
does a specific job to keep the cell alive.
26. The model that represents how proteins, phospholipids, and other cell
membrane components are able to move around within the cell membrane is
called the___________________________.
Fluid Mosaic Model
27. Draw a picture of the cell membrane showing where a peripheral protein
might be located.
peripheral protein would be found on the inner or the outer surface of cell memb.
28. What does a channel (or transport) protein in the cell membrane do?
transports water, ions, or anything charged that can’t get through the lipid bilayer
on its own
29. What is the role of a receptor protein on the cell membrane?
receives outside information and transmits it into the cell
30. The organelle that uses sunlight to make food for the plant during
photosynthesis.
chloroplast
31. The region of the cell between cell membrane and nucleus where the
organelles are found.
cytoplasm
32. The gelatin-like fluid in the cytoplasm that bathes the organelles.
cytosol
