In our diffusion lab the plastic bag was semi-permiable like the cell membrane. ___________ could diffuse through it but ________ could not.
iodine could, corn starch could not.
200
In diffusion molecules move from areas of ______ concentration to ______ concentration until the concentrations on both sides are _______.
What is high to low until equal.
200
This is why cells need to be small.
What is so they have a large surface area to volume ratio.
(so there is enough surface area to absorb materials to support the volume of the cell )

What is corn syrup.
300
Iodine was an _________ for __________ in our cell size lab. (not on quiz)
What is an indicator for starch.

These are the 3 materials required for photosynthesis.
What are carbon dioxide, water and energy.
300
What are the products of cellular respiration?
What are carbon dioxide, water and energy.
300
Name 3 things a plant cell has that an animal cell does not.
What is cell wall, chloroplast, square shape, large central vacuole, green color.
400
If a carrot is soaked in pure water, it will cause water to diffuse into the carrot cells by osmosis. Why is this?
What is because there is a higher concentration of water molecules outside the cell than inside.
400
These molecules are embedded in the cell membrane and move around within the layer. ( not on quiz)
What are protein molecules.
400
These are the products of photosynthesis.
What are glucose and oxygen.
400
How are photosynthesis and cell respiration related?
What is they are opposite processes. Photosynthesis gives off oxygen and glucose which cell respiration takes in. Cell respiration gives off water, carbon dioxide and energy which is why photosynthesis starts with.
400
These are the 5 characteristics of living organisms.
What is are made of cells, grow and develop, reproduce, respond to stimuli and use energy.
500
These are the four functions of the cell membrane.
-protect the cell
-take in food
rid cell of waste
- interact/communicate
