What does the unified cell theory include?
Every living thing is made of one or more cells.
Cells are made of even smaller particles of matter.
Cells are the basic unit of life.
New cells are made of existing cells.
Cells make up only plants.
What is the difference between eukaryotic and prokaryotic cells?
Eukaryotic cells are more complex.
Prokaryotic cells have more organelles.
Prokaryotic are unicellular while eukaryotic are multicellular.
DNA in a eukaryotic cell is stored in the nucleus and prokaryotes store it in the cytoplasm.
Eukaryotic cells lack vesicles, vacuoles, and other storage organelles.
Is it better for a cell to be smaller or bigger in size?
The cell is better when bigger in size because it can have more functions than smaller cells.
The cell is better when smaller in size because it will lack organelles and be simpler.
The cell is better when bigger in size because it can take more space and doesn't need to share with other cells.
The cell is better when smaller because many things, like proteins, won't be able to travel as fast and will be slower if it is big.
What do plant cells have that animal cells don't?
Cell wall
Cytoplasm
Chloroplasts
Lysosomes
Animal cells have temporary (a) , which plant cells do not.
What letter represents the Rough ER?
A
E
M
H
K
What number represents the chloroplasts?
1
5
13
8

A (a) separates the nucleus from the cytoplasm and provides structural support. (Hint:two words)
The (a) synthesizes lipids, such as phospholipids. (Hint: two words)
The Golgi apparatus does what?
Packages proteins
produces proteins
Adds tags to proteins based on where they're going
Moves them through a series of stacked compartments
Explain the term "selectively permeable" in relation to the membrane
The membrane-spanning protein...
transports things like ions and small molecules
lies inside the cell and pulls things from the membrane
acts as the cell membrane vacuole and stores minerals
detects danger and gives a signal of caution to the nucleus
The surface proteins...
communication between other cells and external environments
only provide the cell with more support
produces phospholipids
acts as a transport channel for big molecules
The _____ of a phospholipid is hydrophobic while the _____ is hydrophilic.
head; tail
body; legs
tail; head
tail; tail
(a) transport requires energy.
How does the concentration gradient go?
low to high
big to small
high to low
small to big
wide to far
What substances can easily cross the membrane?
water
gasses
nonpolar molecules
little lipids
ions
What substances cannot cross the membrane easily?
Ions
small molecules
large molecules
elements
aquaporins
What does facilitated diffusion use that passive diffusion doesn't?
(a)
A _____ is what dissolves. The ______ is what the substance dissolves in.
solvent; solute
Solution; concentration
solute; solvent
concentration; solution
_________ is when large molecules are needed inside the cell, so the cell membrane engulfs it and then turns it into a vesicle to bring into the cell.
Exocytosis
Endocytosis
Facilitated diffusion
Active transport
_______ is when molecules are moved out of the cell when a vesicle attaches to the membrane and releases them.
Endocytosis
Passive transport
Exocytosis
osmosis
A cell shrinks when put into a solution that is (a) .
A cell swells and can potentially burst when put into a solution that is (a) .
When a cell has water that leaves in and out normally, the solution the cell is in is (a) .
A(n) (a) cell will shrivel and die when placed in a hypertonic solution. But, when placed in a hypotonic solution, it can swell and burst from the water intake.
A(n) (a) cell will shrivel and crumple when placed in a hypertonic solution. But, when placed in a hypotonic solution, it can swell and will not burst due to an extra layer of support.
What organelle absorbs sunlight to make food for the plant cell?
Chloroplasts
Central vacuole
Chlorophyll
Cytoplasm
What organelle produces proteins?
Cell membrane
Nucleolus
Golgo apparatus
Rough ER
