prokaryotic and eukaryotic cells

What does the cell membrane do?

Controls what comes in and out of the cell

What is the purpose of the cell wall?

Gives strength and support in plants and bacteria

What takes place in the cytoplasm?

Most chemical reactions in the cell

What is a eukaryotic cell?

A cell that has a nucleus

What helps some prokaryotic cells to move?

Flagella

What contains the genetic information in a eukaryotic cell?

Nucleus

What are sub-cellular structures?

structures inside a cell that carry out specific functions

What are plasmids?

Circular loops of DNA in bacteria containing useful genes

What is the function of ribosomes?

Assembling proteins

Where is genetic material found in prokaryotic cells?

Inside the cytoplasm

What is an example of an organism made of prokaryotic cells?

Bacteria

How do prokaryotic cells differ from eukaryotic cells in terms of DNA structure?

Prokaryotic cells have a circular loop of DNA, eukaryotic cells have linear DNA

What is the function of the slime capsule in some prokaryotic cells?

Protects the cell

Give the key difference between prokaryotes and eukaryotes.

Prokaryotes do not have a nucleus. Eukaryotes do.

True or false, prokaryotes have a cell wall.

TRUE

Give the name of extra small DNA rings found in some prokaryotes?

Plasmids

What is the function of flagella?

To allow the cell to swim and move around

State a difference between animal cells and bacteria.

Animal cells have: No cell wall and plasmid, linear DNA; Bacterial cells have: Cell wall and plasmid, circular DNA

Give a similarity between plant cells and bacterial cells.

Both have cell walls (but different material)
