UNIT 1- Cells and Multicellular organisms Flashcards
What is the difference between a Prokaryotic and Eukaryotic Cell?
Prokaryotic is a simple cell that does not contain a nucleus or complex organelles. It has 2 domains (unicellular).
Eukaryotic is a complex cell that contains a nucleus and complex organelles. It has 4 domains (often multicellular).
What are the 2 domains Prokaryotic cells are found in?
Bacteria and Archaea
What are the 4 domains Eukaryotic cells are found in?
Plants, Animals, Fungi, Protists
What are the similarities between Prokaryotic and Eukaryotic cells?
They both have:
- ribosomes
- cell membrane
- DNA
- have a cytoplasm
What are plasmids?
They carry a small number of non-essential genes and are copied independently of the chromosome inside of the cell.
What is flagella?
It is primarily used for cell movement. It helps propel a cell through the liquid.
What is a cytoplasm?
It surrounds the organelles through a jelly like fluid.
What is the slime capsule?
It is the outermost layer that helps the cell cell stick to offer cells and surfaces in their environment
What are ribosomes?
They create protein
What is the cell membrane?
It separates inside of the cell from the outside environment.
What is a nucleoid?
Holds DNA and other proteins
What is the Pilli?
Attaches a bacterial cell to specific surfaces or other cells.
What substance does the smooth endoplasmic reticulum produce?
Liquids (fat and oil)
Describe the role of the rough endoplasmic reticulum?
Helps photosynthesis and transports materials
Why do plants still needs mitochondria despite being able to make their own food?
Because plant cells rely on photosynthesis which requires the sun, however when it is raining or during night, mitochondria is required.
Why do you find more mitochondria in muscle cells then skin cells?
As muscles work harder and consumer more energy.
