Cell review
What are five functions of the cell membrane?
Why are organelles membrane bound?
Which organelles and cell structures are common to all cells?
Which are found only in plants?
Which are found in plants, but not in animal cells?
What would you find in bacteria that would help you to identify that it has to be a bacteria cell?
What is the order of organelles that make up the endomembrane system useful for secreting substances from the cell?
What type of transport is used in secreting substances from the cell?
What type of transport would a bacteria use to eat a bacteria cell?
What organelle does transcription occur in?
What organelles do translation occur on?
In the lab distilled water is pure and is definitely _____________ to the potato.
This means the potato is _____________ to the pure water.
Pure water would be considered to have a __________ water potential.
The potato in pure water __________ mass.
The point at which the line on the graph crosses the x-axis is called the ______________ point, where the solution concentration is _____________ to the cells of the potato.
In a very sugary solution the potato is ______________ to the solution and therefore___________________ mass.
The solution is H___________________ to the potato cell.
Name three molecules that move by passive transport through the phospholipid part of the cell membrane.
Glucose is large and P____________ and must go through a P________________. We call this F__________________ diffusion.
Osmosis is the movement of _________________ across the cell membrane, form an area of ___________ water potential to _____________ water potential. This means water flows by passive transport form an area where there is more water to less water.
It continues until the inside and the outside of the cell reach E__________________ .
Active Transport includes any time you change the shape of the C__________ M__________, or the shape of a P_________________ such as the Na+/ K+ pump.
Active transport uses _____________ to move molecules _______________ the gradient, or from an area of _____________ solutes to _____________ solutes.

3-D Cell Project
Make a 3-D model of the assigned cell (prokaryote-bacteria, eukaryote-animal, or eukaryote-plant). Use pictures of cells to get the proportions and shapes of the organelles correct. Have a section cut off of it so that we get a look inside. All appropriate organelles and membranes must be represented. Use pins and flags to ID the parts of use a key on the side.
You will be graded on content, accuracy, grammar and artistic creativity.
Make it colorful and artistic, make sure you can resolve the different structures.
It should be about the size of a shoe about 11”-12” long, or about the size of a shoe box.
Written portion:
Make sure to define and /or describe the structure and the function of any of the structures that are found in your assigned cells.
Include the terms: selectively permeable, cellular respiration, photosynthesis, bilipid, fluid, digestive, heredity, mitosis, protein synthesis, assembly, support, movement, secretion, convoluted, surface area, chemical reactions, specific chemicals that they use for structure and energy storage.
