🗑
Bacteria are ___karyotes. Humans are ___karyotes.   Pro, Eu  
🗑
Prokaryote or Eukaryote: which has a nucleus?   Eukaryote  
🗑
Prokaryote or Eukaryote: which have membrane bound organelles?   Eukaryotes  
🗑
Organelle   structures within eukaryotic cells that cary out specialized functions  
🗑
Which organelle might be called the CEO of the cell because it determines what gets made?   Nucleus  
🗑
Which organelle might be called the factory because it makes things?   Endoplasmic Retilculum  
🗑
2 types of Endoplasmic Recticulum   Rough ER and Smooth ER  
🗑
Difference in external appearance between smooth and rough ER   Rough ER is covered with ribosomes, giving it a bumpy exterior.  
🗑
Explain how the products of smooth and rough ER differ   Rough ER makes proteins. Smooth ER makes carbohydrates and fats.  
🗑
What does the Golgi Apparatus do?   Modifies, packages, stores, and ships the products made by the ER  
🗑
Tay Sach’s disease involves a malfunction of which organelle?   Golgi Apparatus  
🗑
What do you call the sacs in which the Golgi packages the cellular products?   Vesicles  
🗑

🗑
Adenosine Triphosphate (ATP)   the form of energy used by all cells  
🗑
T or F: mitochondria are only passed down the maternal line   True. Sperm don’t have mitochondria.  
🗑
Cytoskeleton is made of protein strands called _______ and protein tubes called _______   microfilaments; microtubules  
🗑
T or F: Cytoskeleon is involved with transportation within the cell   True  
🗑

🗑
Inner layer of phospholipid bilayer: hydrophilic or hydrophobic?   hydrophobic  
🗑
Cholesterol    
🗑
T or F: the content of the membranes is constantly changing   True  
🗑
How does passive transport differ from active transport?   No energy required in passive transport  
🗑
T or F: osmosis refers to the movement of water   True  
🗑
Diffusion: molecules move from area of ____ to ____ concentration   high to low  
🗑
Does diffusion require energy?   No  
🗑
T or F: neither active transport, exocytosis, nor endocytosis require energy   FALSE, they all require energy  
🗑
Concentration gradient   the distribution of molecules is not equal  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
