in an organism (= basic unit of life)
3. Cells come from the reproduction of ______________________
2. List the scientists who made the following contributions to the cell theory.

3. Use the pictures above (cells A-C) to answer the questions below.
Which cell is an animal cell?
Which cell is a plant cell?
Which cell is a eukaryotic cell?
Which cell is a prokaryotic cell?
4. Name two organelles found in plant cells that are NOT seen in animal cells.
_______________________ and __________________________
5. Name two differences between prokaryotic and eukaryotic cells.
________________________and___________________________________
6. Fill in each organelle for each junction.
Small structure in a cell that performs a specific function is the
_O_ __ __ __ __ __ __ __ __.
Dark spot(s) in the nucleus where ribosomes are made would be the
_N_ __ __ __ __ __ __ __ __.
Part the digests cell wastes = _L_ __ __ __ __ __ __ __
The _C_ __ __ __ _W_ __ __ __ is found outside the cell membrane in plants and bacteria and provides support and protection.
Organelle that burns sugars to produce energy is the
_M_ __ __ __ __ __ __ __ __ __ __ __
The _N_ __ __ __ __ __ __ is the control center of the cell.
_F_ __ __ __ __ __ __ __ are long tails that help move the cell.
The _C_ __ __ __ __ __ __ __ __ is the gel-like material.
The ER works to _M_ __ __ __ proteins.
_C_ __ __ __ __ __ __ __ __ __ __ are where photosynthesis happens in plant cells.
A _G_ __ __ __ __ _B_ __ __ __ packages proteins for the cell.
The cell part used for storage is the _V_ __ __ __ __ __ __
_R_ __ __ __ __ __ __ __ __ are small structures that make proteins.
_C_ __ __ __ __ __ __ __ __ __ __ __ provides support and structure
_C_ __ __ __ __ are many short hair-like structures on the surface of a cell that help move the cell or move substances past the cell.
The _C_ __ ___ ___ _M_ __ __ __ __ __ __ __ surrounds all cells and is _S_ ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ _P_ ___ ___ ___ ___ ___ ___ ___ ___ to control what enters and leaves the cell.
7. Label each part of the cells. Tell if the cell is a plant cell or animal cell.
Cell A _______________________________
[pic]
Cell B ________________________________
[pic]
8. Draw a phospholipid.
Label the phosphate head and lipid tails.
Label which part is hydrophilic/hydrophobic
9. List the 2 parts of the cell membrane
10. What does it mean to be selectively permeable?
11. Why is the cell membrane described as a bilayer?
12. Why is the cell membrane described as a fluid mosaic model?
13. DRAW PICTURES!!!!
A cell that is 70% water, 5% protein and 2% sugar is put into a solution that is 65% water, 7% protein and 3% sugar.
Water will move __________________.
Sugar will move __________________.
Protein will move _________________.
A cell that is 70% water, 5% protein, and 2% sugar is put into a solution that is 75% water, 3% protein, and 1% sugar.
Water will move __________________.
Sugar will move __________________.
Protein will move _________________.
A cell that is 70% water, 5% protein, and 2% sugar is put into a solution that is 70% water, 5% protein, and 4% sugar.
Water will move __________________.
Sugar will move __________________.
Protein will move _________________.
OSMOSIS
( isotonic, hypertonic, or hypotonic = bonus words)
*remember that the black dots cannot pass through the membrane – the open space represents water…which can pass through the membrane.
14. Draw an arrow to indicate the movement of water, in each diagram (into/out of cell), and then tell what happens to each cell (stays the same, shrink, swell)
[pic] [pic] [pic]
______________ ______________ _________________
15. If the solute (dots) in this diagram is unable to pass through the dividing membrane, what will happen?
A. the water level will rise on the right side of the tube
B. the water level will rise on the left side of the tube
C. the water level will stay equal on the two sides
16. Fill in the table
