4.1 Prokaryotic Cells 8th

What are the two broad categories of cells?

• prokaryotic and eukaryotic
• prokaryote and nucleoid
• eukaryotes and cells
• bacteria and archaea

Prokaryote are?

• simple, mostly single-celled organism that lacks a nucleus, or any other membrane-bound organelle.
• have a peptidoglycan cell wall and many have polysaccharide capsules.
• have a true nucleus, which means the cell's DNA is surrounded by a membrane.
• contain membrane-bound organelles, such as the nucleus

Four common components of a cell are?

• plasma membrane, cytoplasm, DNA, and ribosomes.
• archaea, bacteria, nucleoid, protiens
• plants, fungi, protists, and animals

plasma membrane

• consisting of a jelly-like cytosol within the cell which other cellular components are found
• the genetic material of the cell
• an outer covering that seperates the cell's interior from its surrounding environment
• synthesize proteins

cytoplasm....

• consisting of a jelly-like cytosol within the cell in which other cellular components are found.
• an outer covering that seperates the cell's interior from its surrounding environment

• synthesize proteins

ribosomes

• an outer covering that separates the cell's interior from its surrounding environment
• the genetic material of the cell

• ribosomes
• flagella
• cell division
• diffusion

Which type of cell?

• Prokaryote
