Question 8
Question
How are bacteria cells specialised?
Answer
Flagella enable the cells to move
A slime capsule which helps the cell stick to surfaces and protect it
Plasmids which carry extra genetic information
Many mitochondria to provide energy for movement
A nucleus to hold the genetic information
