LB Honors Biology - Prokaryotic cells

Prokaryotic cells are found in which two Domains?

• Archaea and Eukarya

• Archaea and Bacteria

• Bacteria and Eukarya

• Bacteria and Protista

The DEFINING feature of the prokaryotes is

• they have no nucleus

• they are always larger than eukaryotes

• they don't have cell walls

• none of the above

Which of the following structures can be used for DEFENSE in prokaryotic cells? (you can choose more than one answer)

• cell wall

• capsule

• ribosome

• chromosome

• lipopolysaccharide (LPS) layer

Prokaryotic chromosomes are _____________.

• linear

• circular

• single-stranded

• all of the above

What size are prokaryotes? (typically)

• 1-10 millimeters

• 10-100 millimeters

• 1-10 micrometers

• 10-100 micrometers

Which of the following structures provides motility (movement) in some prokaryotes?

• cilia

• motor protein

• centriole

• bacterial flagellum (a)

A lipopolysaccharide layer around a cell has which of the following properties?

• attracts sugars

• short-term energy storage

• repels water

• attracts sodium and chloride

What is one difference between Archaea and Bacteria?

• Bacteria have peptidoglycan in their cell walls, Archaea do not

• Archaea have peptidoglycan in their cell walls, Bacteria do not

• Archaea have a nucleus, Bacteria do not

• Bacteria have a nucleus, Archaea do not

Which of the following features are shared by BOTH prokaryotic and eukaryotic cells?

• plasma membrane

• endoplasmic reticulum (ER)

• ribosome

• Golgi

• nucleus

This feature allows a prokaryote to survive in an inhospitable environment by "waiting it out" until the environment becomes more conducive to life.

• circular chromosome

• ribosome

• cytoplasm

• endospore
