Active transport
Active transport is when substances pass through the cell membrane without the help of extra energy.
False
In the gummy lab the salt water did what to the gummy?(Did it grow shrink explode, etc)
It shrank
Movement of molecules from high to low concentration.
Diffusion
What is Endocytosis?
Endocytosis is the vesicle transport into the cell.
Why does active transport require energy?
Answer: Because it moves substances from a low concentration to a higher concentration.
In the kimchi lab the salt that we put in the lettuce made it shrivel, Why
The salt sucked the water out.
This type of transport does not require energy from a cell.
Passive transport
What is Exocytosis?
Exocytosis is the vesicle transport out of the cell.
What is the main difference between active transport and passive transport?
Answer: Active transport requires energy to move substances, while passive transport does not require energy.
In the gummy bear lab why did the gummy bear swell in the sugar water
The gummy bear had a lower concentration.
Diffusion that uses protein channels in the cell membrane.
Facilitated diffusion
How are Endocytosis and Exocytosis different?
Endocytosis brings materials into the cell whereas, Exocytosis takes them out.
Active transport is the opposite of diffusion
True
In the gummy bear lab what was the formula for volume of the bear
Length x width x height
Movement of water molecules across a membrane.
Osmosis
How are Endocytosis and Exocytosis important to the cell?
They help the cell take in nutrients and take out wastes or important molecules.
What is the source of energy used in active transport?
ATP
When the salt sucked the water out of the lettuce what was it called?
Osmosis
The cell part that controls what enters and leaves the cell.
Cell membrane
What part of the cell is mainly involved in Exocytosis and Endocytosis.
The cell membrane.
