Question 1
Which of the following are considered Protista? (Select all that apply)
• Bacteria
• Yeast
• ✓ Algae
• ✓ Amoeba
Correct Answer: Algae, Amoeba
Feedback: Protista are eukaryotic microorganisms that include algae and amoeba (bacteria are
prokaryotes; yeast are fungi).
Question 2
Protista retain unicellular classification, as they are unable to form tissue layers. True or False?
• ✓ True
• False
Correct Answer: True
Feedback: A defining feature of Protista is the inability of colonies to form true tissue layers.
Question 3
The function of the lysosome is (select the best answer):
• To produce energy (ATP)
• Protein synthesis
• Lipid synthesis
• ✓ Waste disposal via hydrolytic enzymes
• Protein modification and distribution
Correct Answer: Waste disposal via hydrolytic enzymes
Feedback: Lysosomes are the cell’s “recycling center” — hydrolytic enzymes break down waste and
damaged organelles.
, Question 4
The function of the ribosome is (select all that apply):
• Waste disposal via hydrolytic enzymes
• To produce energy (ATP)
• ✓ Protein synthesis
• Lipid synthesis
• Protein modification and distribution
Correct Answer: Protein synthesis
Feedback: Ribosomes carry out protein synthesis (translation). Modification/distribution is the role of
the ER and Golgi.
Question 5
Identify the following cellular components by matching the number with the description: (1) Rough
endoplasmic reticulum, (2) Golgi apparatus, (3) Nucleus, (4) Cell wall, (5) Plasma membrane, (6)
Centriole, (7) Lysosome.
✓ Answer: Use the diagram above to identify each labeled organelle. Key features: the
nucleus is the large yellow sphere; the rough endoplasmic reticulum is the
ribosome-studded membrane network; the Golgi apparatus sits to the left as flattened
stacks; lysosomes are small spheres near the Golgi; the plasma membrane is the
outermost boundary.
