The cell membrane is made up of a ______________ bilayer
Phospholipid
100
What does active transport require that passive does not?
Energy (ATP)
100
Which direction is concentration pulled in passive transport?
High to low concentration
100
Name the process that changed the sizes of the cells due to the movement of the water
Osmosis
200
Name one difference between prokaryotes and eukaryotes.
Prokaryotes do not have a nucleus/organelles
200
What is the job of the lysosome?
Breaks down and removes waste
200
In active transport, molecules move from areas of _____ concentration to areas of _________ concentration
In active transport, molecules move from areas of LOW concentration to areas of HIGH concentration
200
Some students are smoking in the bathroom across from Mr Murphy's class. After 5 minutes, Mr Murphy smells smoke and heads to the bath to investigate. What process allowed Mr Murphy to smell the smoke?
Diffusion
200
In the syrup, the egg shrunk because water left the egg. Why did water leave the egg?
The concentration of water outside the egg was lower than inside the egg, so the water left (High to low)
300
What are the 2 differences between active and passive transport?
Active requires energy and moves from low to high concentration
Passive does NOT require energy and moves from high to low concentration
300
What part of the cell reads instructions from the nucleus and creates new proteins?
Ribosome
300
What process brings large molecules into the cell by engulfing it with the membrane, forming a vesicle?
Endocytosis
300
During an experiment, a biology student places a fresh lettuce leaf into a salt water solution. The leaf starts to wilt after several minutes due to what process?
Osmosis
300
In fresh water, the egg got bigger because water entered the egg. Why did water enter the egg?
The concentration of water outside the egg was higher than the concentration inside, so the water moved into the egg (High to low)
400
Name one type of passive and one type of active transport. Make sure to label each
Passive: Diffusion, osmosis, facilitated diffusion
Active: Protein pumps, endocytosis, exocytosis
400
This organelle wraps a membrane around proteins so they can leave the cell or travel to where they need to go.
Golgi Apparatus
400
What process removes waste and other large molecules from the cell?
Exocytosis
400
What type of passive transport is a pump protein most similar to?
Facilitated diffusion (both use proteins)
400
Why will an egg soaked in salt water stay about the same size?
The concentration of water and salt inside and outside of the egg was about the same (Reached equilibrium)
500
The fluid mosaic model describes
What is plasma membrane
500
This organelle gives plant and bacteria cells support and shape.
Cell Wall
500
In protein pumps, what molecule needs to bind to it in order for it to open?
ATP (Energy)
500
What type of passive diffusion requires proteins?
What is facilitated diffusion
500
What tonicity is it when water will enter the cell as fast as it leaves the cell?
