|
What is facilitated diffusion? |
When medium sized non-lipid based molecules enter the cell through carrier proteins |
|
|
Do plastids contain their own DNA? |
Yes |
|
|
Do plastids follow the theory of endosymbiosis? |
Yes |
|
|
In what situation is the potassium/sodium pump in a cell is used? |
Sodium leaks into the cell and needs to be pumped out to reset neurons for another action potential. |
|
|
Why is it called a "membrane pump"? |
The carrier proteins are called pumps because they transport substances from areas of high concentration to low. |
|
|
How do you trigger an action potential (electrical impulse)? |
Sodium ions enter the cell |
|
|
Is the cell self-sustainable? |
YES |
|
|
What is the cell membrane also called? |
Fluid mosaic model |
|
|
What are carrier proteins also called? |
Ion channels |
|
|
Does ACTIVE TRANSPORT need ATP? |
no |
|
|

|
|
Does the mitochondria have its own DNA? |
Yes |
|

|
Since plant cells cannot be in a hypotonic state, what do they develop instead? |
Tuggor pressure. |
|
|
What is tugger pressure? (State the percentages of solute to solvent) |
When there is an enlarged vacuole and allows the plant to stand up. It has 20% solute and 80% solvent. |

|
|
Is the Endoplasmic Reticulum an extenuation of the nuclear membrane? |
yes |
|
|
What are the three things that plant vacuoles contain? |
Enzymes, waste and water |
|
|
What does the vacuole do when it is full of water? |
The vacuole will create water pressure to help the plant stand up |
|
|
What happens to the plant when it doesn't get enough water? |
It will wilt and sag |

Microtubules and microfilaments |
|
|
What acts as a cytoskeleton OUTSIDE of the cell? |
Cilia and flagella |
