Cell Biology 1
What is the basic unit of life that all living things are made of?
Cells
True or False: organelles are bigger than cells.
False: cells have organelles inside them.
What is a definition for "diffusion"?
Spreading Out, moving from high concentration to low concentration.
How many sugars is a simple carbohydrate made of?
1 or 2 sugars
What do genes do?
Many answers: tell our cells and bodies what to do, give us the traits we get from our parents, etc.
What is the scientific name for a living thing? (HINT: it may help to think of the levels of organization)
Organism
What is the name of the gel/liquid inside of a cell?
a) Chloroplast
b) Ectoplasm
c) Blood
d) Cytoplasm
d) Cytoplasm
In the image shown, which of the beakers shows a higher concentration of red molecules?
The left beaker.
Give an example of a food with complex carbohydrates in it.
Many examples.
The four DNA bases are A, G, T, and C. What are the pairs that they always make?
A with T, and C with G.
What organelle is used for creating energy that the cell can use?
Mitochondria
A plant getting plenty of sunlight and water, but is still not able to create food for itself. Which organelle is probably not working correctly?
Chloroplast
What direction do molecules move during active transport?
low concentration to high concentration
When Mr. Woolley gives out candy, what kind of carbohydrate is he most likely giving you?
Monosaccharide
Put the following objects in order from biggest to smallest:
Nucleus, Gene, DNA Base, Cell, Chromosome
Cell, Nucleus, Chromosome, Gene, DNA Base
What are the 2 organelles that plant cells have but animals cells don't? (You have to get both right in the same answer or it doesn't count)
Chloroplast and cell wall
DAILY DOUBLE: Explain what organelle makes a plant cell strong, and why they need it but animal cells don't.
Cell wall, since plants don't have bones to keep them strong like animals do.
What is the difference between simple diffusion and facilitated diffusion?
Simple just lets diffusion happen, but facilitated diffusion helps it happen by providing a door/gate.
What are the 3 types of atoms (3 elements) that a carbohydrate is made of?
Carbon, hydrogen, oxygen
Explain why DNA replication is necessary before cell division.
Otherwise there will be less and less DNA in every new cell you make.
Which organelle would be most responsible for performing facilitated diffusion? Explain how you know.
Cell membrane, since the cell membrane is what determines what enters/exits the cell. Facilitated diffusion is a method of helping certain things come in or out of the cell, and that involves passing through the cell membrane.
Name 2 organelles and a way that they might work together.
Many answers possible.
Clark is having a seizure! What might be going on in his body to cause the seizures?
Too much water is diffusing into his brain, due to higher salt concentration in his brain than in his blood.
Does eating foods with lots of monosaccharides, disaccharides, or polysaccharides put us at the highest risk of getting diabetes? Explain why?
Monosaccharides, because they boost your blood glucose the fastest. They do this because they do not need to be broken down first, since they are already the smallest (glucose is a monosaccharide).
Explain the steps (in the correct order) that happen during DNA replication.
An enzyme helps the DNA double helix unwind, then the two DNA strands split apart, then a different enzyme starts making new strands that match the old one by putting in bases that pair correctly (A with T, C with G).
