science unit 2

Bacterium, the simplest living thing, has 8 parts. The parts are DNA, ribosomes, cytoplasm, fimbria, plasma membrane, capsule, and cell wall

​

Parts of a bacterium

​- acts as a protective layer against infection-fighting agents

- composed of sticky sugar that helps cling to surfaces​

Capsule

​

​- holds the contents of the bacterium together

- ​regulates the water that comes in and out

Cell Wall

- regulates chemicals

Plasma Membrane

- produce protein

Ribosomes

​

- a jelly like substance

- holds DNA and ribsosomes​

​​Cytoplasm

- used in locomotion (for moving)

Flagellum

​- used to grasp surfaces

- used for conjugation​
