| Question | Answer |
|---|---|
| What is the smallest functional unit of life? | Cell |
| 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 |
| Which organelles produce ATP (energy)? | Mitochondria |
| 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 |
| Outer layers of phospholipid bilayer: hydrophilic or hydrophobic? | hydrophilic |
| 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 |
