Prokaryotes

​ (a)   are the simplest of all cells.

​ (b)   are prokaryotes and they fall into two major categories:

Eubacteria and Archaebacteria.

​ (c)   are very common, they occur on surfaces and soil.

​ (d)   live in extreme environments, like hot sulfur springs.

Archaebacteria are the oldest forms of life.

A simple way of remembering the two types of bacteria are:

Eu-bacteria (ubacteria) is ​ (a)   bacteria all around and inside of you.

Archae-bacteria (​ (b)   ) are the oldest bacteria, you will never be around them.

Pro-karyotes= ​ (c)   karyotypes, they ​ (d)   have membrane bound organelles such as a nucleus.

• true
• archaic =old
• no
• DO NOT

If bacteria don't make their own food, they have to break down or decompose other organisms dead or alive.

If they depend on others for their food they would be considered:

• Autotrophs

• Heterotrophs

Bacteria have a thick outer covering called a ​ (a)   and just within the cell wall is the ​ (b)   .

On the outside of the cell wall they have ​ (c)   that help bacteria to ​ (d)   and for ​ (e)   or the exchange of genetic material (reproduction)

• cell wall
• cell membrane
• pilus
• conjugation
• stick to surfaces

What structure on the outside of Bacteria allows them to stick to surfaces and exchange genetic material with other bacteria.

• Cell Wall

• Nucleus

• Cell Membrane

• Pilus

Bacteria have​ (a)   that are tail-like which helps them to ​ (b)  

The watery material inside the bacteria is the ​ (c)   .

Sprinkled throughout the Bacteria are ​ (d)   that produce proteins, and are the ONLY ​ (e)   organelles in Bacteria.

• flagella
• move around.
• cytoplasm
• ribosomes
• membrane bound

Label the pilus and flagella of the bacteria

a

b

Pilus

Flagella

What is the only membrane bound organelles in Prokaryotes

(Remember Pro-NO)

• Nucleus

• Rough ER

• Chloroplast

• Ribosomes

Every prokaryotic cells has it's

DNA ​ (a)   within the ​ (b)   because it is ​ (c)   enclosed in a nucleus.

DNA usually looks like a twisted strand of spaghetti called a ​ (d)   .

DNA contains the ​ (e)   for the cell.

• floating
• cytoplasm
• not
• nucleoid
• instructions
