Cell Organelles
A plant cell is not making enough ATP to keep up with the plant's needs. The mitochondria is functioning perfectly fine, so which organelle is likely not functioning?
Chloroplast
Water moves in which direction for water potential and for osmotic pressure?
Water potential - high to low
Osmotic pressure - low to high
What type of channel allows water to move into/out of the cell?
Aquaporins
According to the endosymbiotic theory, mitochondria started out as a free-living ________________ (specific).
Proteobacteria
When is Ms. Chang's birthday?
October 13
What are two organelles besides chloroplast that plant cells have that animal cells do not?
Plasmodesmata, central vacuole, cell wall
Which way will the water move if the inside of a cell has a concentration of 4.0M and it is in a solution with a concentration of 6.0M?
Out of the cell.
A molecule requires a protein channel to move in and out of the cell WITH the concentration gradient. What type of diffusion is this?
Facilitated diffusion
According to the endosymbiotic theory, chloroplasts started out as free-living ________________ (specific).
Cyanobacteria
What are the two hand soap scents that are at the front sink in the classroom?
Peppermint & Pumpkin
A cell is not keeping up with waste buildup in the cell. There are very few lysosomes available. Which organelle is not functioning properly?
Golgi Apparatus
An increase in solutes leads to higher or lower water potential?
lower
In secondary active transport, what is the purpose of pumping the protons out of the cell?
To create a proton gradient and electrochemical gradient.
Name one example of a compartment in the cell.
Any organelle.
Which NBA player is nicknamed "the alien"?
Despite watering a plant, the stem remains very limp. Which organelle is most likely not functioning?
Central Vacuole
What are the two categories of organisms when they do osmoregulation?
Osmoconformers and osmoregulators
What structure on the cell membrane acts as a receptor for hormones and neurotransmitters?
Glycoprotein
Catabolism: break down molecules and release energy
Anabolism: put molecules together and requires energy
What is the name of the scientist (aka our endosymbiotic theory diva) that we talked about?
Lynn Margulis
What is the order of organelles that a protein would see as it is being made? (start in the nucleus as RNA)
nucleus, ribosome, Rough ER, vesicle, Golgi apparatus, vesicle, cell membrane.
What is the equation for solute potential AND what does each variable mean?
-iCRT
i - ionization constant
C - concentration
R - pressure constant
T - temperature
If the temperature begins to increase, the cell membrane may become too fluid. What will the cell do to the membrane?
The cell will add cholesterol to make the membrane more rigid.
