Semester 1 Review (4's, 5's, 6's & 9's)

Which is true of prokaryotic and eukaryotic cells?

• Prokaryotic cells are larger than eukaryotic cells.
• Eukaryotic cells do not have nuclei, and prokaryotic cells do have nuclei.
• Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles.
• Eukaryotic cells are simpler than prokaryotic cells.

Which do BOTH prokaryotes and eukaryotes contain?

• nucleus

• mitochondria

• ribosomes

• cell wall

Which does only eukaryotic cells contain?

• nucleus

• DNA

• cell membrane

• ribosomes

Prokaryotic cells do not have…….

• membrane bound organelles

• cell membrane

• DNA or RNA

• life

You can distinguish a prokaryote apart from a nucleus by--

• The presence of a ribosome

• The presence of a cell membrane

• The presence of DNA

• The presence of a nuclear membrane

Which illustration of transport across the membrane requires energy?

• A
• B
• C
• D

Which form of transport is being shown in the diagram.

• diffusion
• osmosis
• facilitated diffusion
• active transport

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport
• Passive transport
• Diffusion
• Osmosis

When a cell forms a vesicle around unwanted particles and expels it OUT of the cell.

• Pinocytosis

• Endocytosis

• Receptor-mediated

• Exocytosis

Which type of active transport uses a vesicle to allow a large molecule to exit the cell?

• Endocytosis

• Exocytosis
