Some eukaryotic organisms are____(algae, yeast, amoeba, etc) while others are____(all plants, all animals, mushrooms, seaweed, etc).
Some eukaryotic organisms are__unicellular__(algae, yeast, amoeba, etc) while others are__multicellular__(all plants, all animals, mushrooms, seaweed, etc).
Simple Diffusion moves what type of molecules and moves them to from areas of __ concentration to areas of __ concentration.
Simple diffusion moves small nonpolar molecules. Also moves them from high to low.
Plant cells contain most the components of animal eukaryotic cells, plus:___, ___, Central___, but no ___.
Plant cells contain most the components of animal eukaryotic cells, plus:__cell wall_, __chloroplast_, Central_vacuoles_, but no _Iysosomes__.
Why is it important that the cell membrane is a selectively (semi) permeable membrane?
The cell membrane can allow certain things that it needs to pass through and keeps harmful things out.
What's the memory clue for Hypotonic solution?
Hypo-Hippo
Are Ribosomes membrane bound organelles?
No
Facilitated diffusion moves what type of molecules?
They move large and polar molecules.
Passive Transport- Moves molecules from areas of ___ to __ concentration (__ the concentration gradient).
Passive Transport- Moves molecules from areas of _high__ to _low_ concentration (_with_ the concentration gradient).
What are some examples of things that must Enter or Leave the cell
Enters: Water, Food, Oxygen
Leaves: water, waste, carbon dioxide
What's a memory clue for isotonic solution?
Iso-Equal

Ribosomes are not membrane-bound organelles, but they are still present in eukaryotic cells. __Amino__ _acids__ are bonded together to make__proteins_ at the ribosomes. In eukaryotes, sometimes ribosomes float in the cytoplasm, and sometimes they are embedded in the membrane of rough ER.
Protein Pumps moves what type of molecules? Does it need protein and what areas do they move from?
Does simple Diffusion need protein?
Yes or no
No

Define Hypotonic solution.
A solution with a low solute concentration but high H2O concentration.
Rough ER: ribosomes attached to the surface. __ are made here, then travel through the tunnels of the ER.
proteins
Endocytosis moves what type of molecules? Do they move into a cell or out of cell?
Endocytosis moves large molecules, and they move into cells.
Does protein pumps, Endocytosis and Exocytosis use Passive or Active transport?
Active transport
List different names of the cell membrane.
Plasma membrane
Phospholipid Bilayer
Where is the area of high solute concentration in hypertonic solution?
High solute is outside the cell.
Sooth ER no ribosomes are present;___ are made here. Toxic substances are ___ down.
Sooth ER no ribosomes are present;__Lipids_ are made here. Toxic substances are _broken__ down.
Exocytosis moves what type of molecules? Do they need proteins, and do they need energy?
They move large amounts of molecules. They also don't need proteins, but they do need energy.
Does simple Diffusion, facilitated diffusion and Osmosis need energy and do they use Passive or Active Transport?
They don't need energy and they use Passive Transport.
