AP Biology Unit 2 Test Questions and
Answers
2 organelles that contain their own DNA separate from the chromosome
✓ ~~~Mitochondria and chloroplast
What domains fall under prokaryotic cells?
✓ ~~~Bacteria and archaea
What are the basic features of all cells?
✓ ~~~Membrane, cytoplasm, chromosomes, ribosomes
This organelle synthesizes lipids, metabolizes carbohydrates, detoxifies poison, and
stores calcium
✓ ~~~Smooth ER
This cell is characterized by having DNA in a nucleus that is bound by a nuclear
envelope and membrane bound organelles
✓ ~~~Eukaryotic cell
This is a membranous sac of hydrolytic enzymes that can digest macromolecules
✓ ~~~Lysosome
The __________ is a selective barrier that allows oxygen, nutrients, and wastes to
service the volume of every cell
, ✓ ~~~Plasma membrane
Ribosomes use the information from the DNA to make what
✓ ~~~Proteins
This cell type is characterized by having no nucleus, but instead a nucleoid, and no
membrane bound organelles
✓ ~~~Prokaryotic cell
Diffusion through protein channels is known as what?
✓ ~~~Facilitated diffusion
Site of ribosomal RNA synthesis
✓ ~~~Nucleolus
What happens to a plant cell when placed in pure water (hypotonic solution)?
✓ ~~~It becomes turgid, cell wall protects from bursting
Site of photosynthesis
✓ ~~~chloroplast
These vacuoles pump excess water out of the cell
✓ ~~~Contractile
