Cells & Viruses Quiz Review

What are the FOUR things that ALL CELLS HAVE?

• cell membrane

• nucleus

• cytoplasm

• ribosomes

• genetic material

PRO = NO and EU = DO --> what does this mean?

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells DO NOT.

• Prokaryotic cells have NO nucleus and NO membrane-bound organelles, while eukaryotic cells DO have them.

Sort the descriptions as either lytic or lysogenic:

Groups:

(a) Lytic cycle

,

(b) Lysogenic cycle

• causes symptoms quickly

• genetic material combines with host

• causes symptoms slowly

• hides inside the cell

• causes rapid destruction of the cell (lysis - burst)

• genetic material stays separate from host

Imagine you are a scientist studying cells. You are comparing plant cells and animal cells. Can you identify the THREE structures that plant cells have but animal cells DO NOT?

• cell membrane

• chloroplasts

• cell wall

• ribosomes

• large central vacuole

Match the following virus structures with their correct function:

• surface proteins (projections)

• surrounds/protects genetic material

• genetic material (DNA or RNA)

• stores genetic information of the virus

• capsid

• attaches virus to host cell

What do eukaryotic cells have that prokaryotic cells DON'T?

• genetic material

• cell membrane

• ribosomes

• cytoplasm
