Draw the phospholipid bilayer, why is it called semi permeable?
Because it allows some things to pass and others not to
100
What is the main difference between prokaryotes and eukaryotes
What is no nucleus or other membrane bound organelles
100
This is a storage area inside a cell. Draw a plant version and an animal version.
What is vacuole, plant is much bigger
100
What is one similarity and one difference between diffusion and facilitated diffusion?
Diffusion is going from high to low concentration and so is facilitated diffusion however facilitated passes through a protein to pass the membrane
100
What are two differences between passive and active transport?
What is active requires energy, and active goes from low to high concentration
200
This organelle contains very strong, digestive enzymes for breaking things down.
What is the lysosome
200
An example of a prokaryotic organism is ___________
What is bacteria
200
Plant cells have this organelle made out of cellulose.
Write down the organelle and its main function.
What is the cell wall, structure and support
200
A cell which is 4% salt is placed in a beaker with 30% salt.
A. Draw the question
B. Draw an arrow to show which way water will move
C. The cell is ______tonic compared to the solution.
Water moves out, the cell is hypotonic
200
What is a reason a cell would go through endocytosis?
To get nutrients inside the cell
300
This organelle sorts and packages proteins and ships them off to their final destinations.
What is the Golgi apparatus
300
Although prokaryotes do not have membrane bound organelles they do still have to make proteins and have these "organelles" called __________
What is Ribosomes
300
If a scientists wanted to study photosynthesis, what organelle would be important to him/her?
What is the chloroplast
300
Name three kinds of passive transport.
Diffusion
Osmosis
Facilitated Diffusion
300
Why do protein pumps require energy in active diffusion but protein channels in facilitated diffusion do not require energy?
What is diffusion is going down the concentration gradient and protein pumps are going against the gradient.
400
In your muscles the cells generally require extra energy, what organelle would you expect more of in these cells?
What is Mitochondria, the powerhouse
400
Name three things that are the same in prokaryotes and eukaryotes.
Cytoplasm
Cell membrane
Ribosome
DNA
400
What is plasmolysis? How does it look different in animal and plant cells?
shrinking because of losing water during osmosis, plant cells still stick to the cell wall.
400
A plant and an animal cell are both placed in a hypotonic solution. What happened to each cell.
Animal explode
Plant Become more turgid
400
A: What term means that the cell maintains a balance through self regulating adjustments?
What is Homeostasis
500
If a person has a disease in which his body is not breaking down old materials properly, what organelle would you suspect to be the issue?
What is lysosome
500
State where you can find the chromosomes in a Eukaryote and where you find the chromosomes in a prokaryote.
Euk - in the nucleus
Prok- Floating in the cytoplasm
500
What is one benefit and one disadvantage to being a multicellular organism.
What is each cell can be really good at one job, but all the cells rely on each other to stay alive, if one group fails they all die
500
Some molecules require facilitated diffusion to pass through the cell membrane.
a. What part of the membrane (macromolecule) forms a channel through the membrane allowing things to pass through.
b. What organelle must make these?
What is Protein or protein channels made by ribosomes
500
What happens to the movement of molecules when equilibrium has been reached on both sides of the membrane?
It continues to move in both directions but stays at equilibrium
