Prokaryotic vs. Eukaryotic
Which type of cell does not have a nucleus?
Prokaryotic cell
Name one structure found in plant cells but not animal cells.
Cell wall or chloroplast
Which organelle makes proteins?
Ribosome
What does selective permeability mean?
The cell membrane allows some substances to pass while blocking others.
A muscle cell needs large amounts of energy. Which organelle would you expect it to have many of?
Mitochondria
Which structure is the best evidence that a cell is eukaryotic?
Nucleus
Which two structures provide the strongest evidence that a cell is a plant cell?
Which organelle releases usable energy from food?
Mitochondria
What is the nucleoid?
The region in a prokaryotic cell where DNA is located.
A plant cell can no longer perform photosynthesis. Which organelle may be malfunctioning?
Chloroplast
Name the four structures found in all cells
DNA, ribosomes, cytoplasm, and cell membrane
True or False: Plant cells have mitochondria.
True
Which organelle modifies, packages, and ships proteins?
Golgi Apparatus
What is a vesicle?
A small membrane-covered sac that transports or stores materials.
A cell can no longer make proteins. Which structure is malfunctioning?
Ribosome
A cell contains DNA, ribosomes, cytoplasm, and a membrane but no nucleus. What type of cell is it?
Prokaryotic
What is one function of the large central vacuole in a plant cell?
Stores water and helps support the cell
Which organelle breaks down waste and damaged materials?
Lysosome
What is the main difference between rough ER and smooth ER?
Rough ER has ribosomes attached; smooth ER does not.
Put these structures in the correct order for producing and exporting a protein: Golgi apparatus, vesicle, ribosome, rough ER, cell membrane.
Ribosome → Rough ER → Golgi apparatus → Vesicle → Cell membrane
A single-celled organism contains a nucleus and mitochondria. Is it prokaryotic or eukaryotic? Explain.
Eukaryotic. The presence of a nucleus identifies it as eukaryotic, even though it is unicellular.
A cell contains a nucleus, mitochondria, cell membrane, cell wall, chloroplasts, and a large central vacuole. Classify the cell completely.
Plant eukaryotic cell
Which structure helps maintain the cell’s shape and internal organization?
Cytoskeleton
What does cell specialization mean?
A cell has structures or features that help it perform a particular job.
A cell contains many rough ER, ribosomes, Golgi structures, and vesicles. What kind of job is this cell probably specialized to perform?
Producing and exporting large amounts of protein
