Prokaryotic Cells |
Cells without membrane-bound organelles. Bacteria and Archaea. |
|
Eukaryotic Cells |
Has membrane-bound organelles |
|
What do plant cells have that animal cells do not? |
A cell wall made of cellulose, chloroplasts, and central vacuoles |
|
What do animal cells have that plants do not? |
Lysosomes, microvili, and plants do not typically have flagellum or need for a cytoskeleton |
|
ATP is? |
Potentially the most important form of energy in biology. Formed by the mitochondria. |
|
How do animal cells keep their structure? |
Cytoskeletons and extra-cellular matrix |
|
How do plant cells keep their structure? |
Cell wall and water stored in central vacuoles pushes on the plasma membrane |
|
What does the cell wall do? |
Provide structure for plant cells |
|
What do choloroplasts do? |
Using photosynthesis, chloroplasts create an energy source for plants. |
|
Which 2 organelles have their own DNA and have 2 membranes each? |
Mitochondria and chloroplasts |
|
Function of central vacuoles? |
Take up most of the plant cell for water storage |
|
Function of lysosomes? |
It's low pH makes it acidic and it contains digestive enzymes |
|
Function of cytoplasm? |
Contains the organelles and absorbs shock from movement |
|
Function of the nucleus? |
Contains DNA information, nucleolus, and centrioles. Also pulls apart chromosomes during replication. |
|
What do Ribosomes do? |
Create protein |
|
Characteristics of Rough Endoplasmic Reticulum? |
Has ribosomes on it which produce protein |
|
Function of Smooth Endoplasmic Reticulum? |
A cell's pharmacy. Creates drugs and toxins. |
|
Mitochondria is responsible for? |
Cellular respiration and making ATP |
|
What does the Golgi Apparatus do? |
It's the UPS of the cell. Takes in particles, modifies them, and transports them out |
|
Peroxisomes have an important function. What is it? |
To neutralize peroxide |
|
What are flagellum for? |
Movement |
|
The most efficient cells are? |
Small cells, due to their high surface area to volume ratio |
|
How do microvili affect surface area? |
Microvili increase surface area |
|
What is an extra-cellular matrix? |
It's like a spider web that provides stability and structure for cells |
