Task 1
Flagellum- allows the organelle to move depending on its chemical agent.
Cell wall- binds to host cells and transfer DNA
Capsule- made of polysaccharides (sugar polymers). Helps prokaryotes cling onto each other, this
helps the cell from drying out.
Nucleoid- controls the activity of the cell, and reproduction information. This is where the genetic
material is stored. Transcription and replication of the DNA take place here.
Plasma nutrients membrane- it provides protection to the cell, has a fixed environment and
transports into the cell. It gets rid of toxic substances out of the cell.
Cytoplasm- protects cellular contents. It transports and maintains the shape of the cell.
Ribosomes- It assembles amino acid to form proteins that are essential to carry out
cellular functions.
Pilus- short hair like structures found on the surface of the cell. They are involved in movement and
are more often involved in adherence to other surfaces.
, DNA nucleic acid- contain, store and express genetic
information.
Capsid- to protect and encounter other host cells.
Collar domain- compresses and punctures the cell.
Deposits the DNA into the bacterial cell.
Sheath- it compresses and DNA into the bacterial
cell.
Base plate- initiates infection when the tail fibres
bind to the host cell.
