Cells Flashcards
What is the function of the ribosomes?
Protein synthesis
What is the function of the mitochondria?
The site of aerobic respiration. Makes ATP.
What is the function of the nucleolus?
Makes ribosomes
What is the function of the smooth endoplasmic reticulum?
The synthesis and transport of lipids
What is the function of the golgi body?
Modifies and packages proteins into vesicles. Produces lysosomes.
What is the function of the centrioles
Help cell division in animals
What is the function of the lysosomes?
Contain digestive enzymes. These can be used to destroy old organelles
or digest material which has been taken into the cell
What is the function of the nucleus?
To store genetic information (DNA)
How are eukaryotic cells different to prokaryotic cells?
They contain membrane bound organelles, including the nucleus. They have linear rather than circular DNA and larger ribosomes
What is a prokaryotic cell wall made of?
Murein/peptidoglycan (same thing)
What is a tissue?
A group of similar cells working together to perform a specific function
What is an organ?
A group of different tissues working together to perform a specific function
What is the role of the rough endoplasmic reticulum?
It is covered in ribosomes and is a site where proteins are made and transported.
What is the function of the plasma membrane? (Also called the cell membrane)
It controls what enters and exits the cell.
Some bacteria have a capsule (also called slime layer). What does it do?
Protects the bacteria from white blood cells and helps them to stick to human cells.
Some bacteria have flagella. What is their role?
To help the bacteria to move around.
What is a bacterial plasmid?
A small loop of DNA that can be exchanged between bacteria.
What are bacterial pili?
Small appendages that stick out from bacteria and can be used to stick them to surfaces or to exchange plasmids.
Are plasmids found in prokaryotic (bacteria) or eukaryotic (animal) cells?
Prokaryotic cells (Bacteria)
Are cell walls found in prokaryotic (bacteria) or eukaryotic (animal) cells?
Prokaryotic cells (Bacteria)
Are nuclei found in prokaryotic (bacteria) or eukaryotic (animal) cells?
Eukaryotic cells (Animal cells)
Is endoplasmic reticulum found in prokaryotic (bacteria) or eukaryotic (animal) cells?
Eukaryotic cells (Animal cells)
Are Golgi bodies found in prokaryotic (bacteria) or eukaryotic (animal) cells?
Eukaryotic cells (Animal cells)
Are lysosomes found in (prokaryotic) bacteria or (eukaryotic) animal cells?
Eukaryotic cells (Animal cells)
Are flagella found in (prokaryotic) bacteria or (eukaryotic) animal cells?
Prokaryotic cells (Bacteria)
