bacteria cells

List the 8 organelles found in a bacterial cell.

• Cell Membrane.

• Cell Wall.

• Slime coat.

• Plasmid DNA.

• Chromosomal DNA.

• Flagella.

• Ribosomes.

• Cytoplasm.

Name one subcellular structure where genes are found within the prokaryotic cells.

Chromosomal or Plasmid DNA.

Are bacteria cells prokaryotic or eukaryotic?

prokaryotic

Is bacteria uni or multicellular?

Unicellular

What are the two types of DNA found in bacterial cells?

Plasmid DNA + Chromosomal DNA.

What is plasmid DNA?

Small circular loops of DNA with useful genes that can be exchanged through various bacterial cells.

What is chromosomal DNA?

Large pieces of DNA floating freely in the cytoplasm to controls the cells activities and replication.

What is the difference between plasmid and chromosomal DNA?

Plasmid - Small circular loops of DNA with useful genes.

Chromosomal - Large pieces of DNA floating freely in the cytoplasm.

What is the function of the flagellum?

Tail used to help the cell move.

What is the function of the slime coat?

Protects the bacterial cell from things like bleach and antibiotics

Is a bacterial cell smaller or bigger than animal/plant cells?

smaller

example of how is plasmid DNA useful

for example, if a certain bacteria has the ability to resist antibiotics, it can share this ability with other bacteria in its colony through exchange of plasmid DNA, meaning that now they whole colony is protected from the antibiotics.
