• Plasma Membrane
• Cytoplasm
• Ribsomes
• Pilus
• Capsule

Which cell part is NOT in animal cells?

• Ribsomes
• Nucleoid (DNA)
• Cell Wall
• Plasma Membrane
• Cytoplasm

Which of the following is the defining characteristic of a Eukaryotic cell?

(Eu=Do)

• presence of a membrane bound nucleus
• DNA is present
• absence of membrane bound mitochondria
• reproduces asexually

Based on the cell features, is this cell a Eukaryote or Prokaryote?

• This is a prokaryote because it has ribosomes that synthesize proteins.
• This is a eukaryote because it has a nucleus.
• This is a prokaryote because it has a cell wall.
• This is a eukaryote because only eukaryotes have cell walls.

What type of cells have a cell membrane?

• Only eukaryotes have an plasma membrane.
• Only prokaryotes have an plasma membrane.
• Both eukaryotes and prokaryotes have an plasma membrane.
• Neither eukaryotes or prokaryotes have an plasma membrane.

Which type of cells have a nucleus?

• Only eukaryotes have a nucleus.
• Only prokaryotes have a nucleus.
• Both eukaryotes and prokaryotes have a nucleus.
• Neither eukaryotes or prokaryotes have a nucleus.

Select the two correct statements about viruses and cells.

• Viruses and cells both have a form of genetic material, such as DNA.
• Viruses and cells both have organelles which perform basic functions.
• Viruses cannot carry out their life cycles unless inside a host cell.
• Viruses and cells both have identical life cycles.

Which statement is correct?

• A virus is basically made up of genetic material surrounded by a protein coat called a capsid. Viruses need a host cell in order to carry out their processes, unlike a cell, which does not.
• A cell is basically made up of genetic material surrounded by a protein coat called a capsid. Viruses need a host cell in order to carry out their processes, unlike a virus, which does not.

Which illness is caused by a virus?

• common colds
• diabetes
• strep throat
• tooth decay

Scientists are designing new medicines to fight infectious diseases caused by viruses. One of the most effective ways these medicines could limit the spread of the virus within the body would be to – What do viruses have to be able to do to reproduce and live?

• prevent viruses from dividing
• burst cells infected with viruses
• stop viruses from attaching to cells
• make it easier for viruses to leave cells
