Cell Basics
What are the 3 domains of life?
Archaea, Bacteria, Eukarya
Why is a plants cell rectangular?
Because of the cell wall
Water Potential measures...
...how likely water molecules are to move.
Name 3 types of Passive Transport.
Diffusion, Osmosis, and Facilitated Transport
Give me two differences between Prokaryotic and Eukaryotic cells.
Eukaryotes have a nucleus, prokaryotes don't.
Eukaryotes are larger and more complex than prokaryotes.
Eukaryotes' chromosomes are in a linear pattern, prokaryotes' chromosomes are in a circular pattern.
As a normal part of an organism's growth or development, a cell needs to be destroyed, what organelle helps with this?
Lysosomes
What is the highest water potential value? Give me an example?
The sodium potassium pump focuses on what type of cells?
Muscle & Nervous Cells
What are the 4 classes of eukaryotic organisms?
Protists, Animals, Plants, Fungi
A cell that focuses on making steroid hormones has a high concentration of which organelle?
The smooth ER
An Intravenous (IV) fluid is hypertonic. What might its pressure potential measure be?
Any negative number; -1, -2, -3, -4, -5, -6, -(insert #)
Which type of osmosis refers to turgor pressure and what does it do to a cell?
Hypotonic; cell will swell.
What are the 4 things both Prokaryotic and Eukaryotic cells have?
DNA, Cytoplasm, Ribosomes, Plasma Membrane
Macrophages ingest and digest many pathogens. Which organelle plays a major role in the activity of macrophages?
Lysosomes
What does the i, C, R, and T, stand for/represent in the solute potential equation?
i is the ionization constant, C is the molar concentration, R is the pressure constant (always 0.0831), and T is the temperature in Kelvin.
How does the Sucrose H+ Cotransporter transport solutes?
They use the concentration gradient of another solute (which was made with ATP).
Give me an example of a Protist.
algae, amoebas, euglena, plasmodium, slime molds, etc
What are the organelles involved in the process of protein synthesis.
The nucleus, ribosomes, endoplasmic reticulum, the golgi apparatus.
What is the solute potential of an open beaker containing 0.6M of Calcium Chloride at 13C? Round to the nearest hundredth.
-42.78
Phagocytosis is type of _________ (which is a type of _________) that can be most commonly used where?
endocytosis; bulk transport; the immune system.
