Organelle Jobs
Which organelle controls what enters and leaves the cell?
Cell membrane
Which type of cell contains chloroplasts?
Plant cell
A cell has no usable energy. Which organelle is most likely malfunctioning?
Mitochondria
True or false: One organelle can perform every job needed to keep a cell alive.
False
A scientist observes a cell with one large central vacuole. Which cell is it most likely?
A. Animal cell
B. Plant cell
C. Bacterial cell
D. Nonliving cell
B. Plant cell
Which organelle provides instructions and controls the cell’s activities?
Nucleus
Name the three members of the Green Team.
Cell wall, chloroplasts, and large central vacuole
Materials are not being packaged or shipped. Which organelle has failed?
Golgi apparatus
What is a system?
A group of parts working together to do a job.
Which statement best explains why mitochondria are important?
A. They provide support and shape.
B. They control what enters the cell.
C. They release usable energy for cell activities.
D. They store water and waste.
C. They release usable energy for cell activities.
Which organelle moves materials throughout the cell?
Endoplasmic reticulum (ER)
Name three organelles found in both plant and animal cells.
Any three: cell membrane, cytoplasm, nucleus, mitochondria, ER, Golgi apparatus, or vacuoles
Harmful materials enter freely, while important materials leave the cell. Which organelle is damaged?
Cell membrane
Why are mitochondria important to the other organelles?
They release usable energy that helps the other organelles perform their jobs.
A cell contains a cell membrane, nucleus, cytoplasm, mitochondria, ER, Golgi apparatus, and small vacuoles. It does not contain chloroplasts or a cell wall. Which type of cell is it?
A. Animal cell
B. Plant cell
C. Both plant and animal
D. Nonliving material
A. Animal cell
Which organelle packages and ships materials to where they are needed?
Golgi apparatus
How are vacuoles different in plant and animal cells?
Plant cells usually have one large central vacuole, while animal cells usually have several smaller vacuoles.
A plant cell can no longer use sunlight to make food. Which organelle is malfunctioning, and how will the cell be affected?
Chloroplasts; the plant cell will not be able to make food properly.
Explain how the nucleus, ER, and Golgi apparatus work together.
The nucleus provides instructions, the ER moves materials, and the Golgi apparatus packages and ships those materials.
A plant cell loses its cell wall. Which result is most likely?
A. The cell loses support and shape.
B. The cell can no longer package materials.
C. The cell can no longer give instructions.
D. The cell immediately produces more energy.
A. The cell loses support and shape.
Which two organelles work together when materials move through the cell and are then packaged for delivery?
Endoplasmic reticulum and Golgi apparatus
A scientist observes a cell with a nucleus, mitochondria, chloroplasts, and a large central vacuole. Identify the cell and give two pieces of evidence.
It is a plant cell because it has chloroplasts and a large central vacuole. A cell wall would also support this conclusion.
The ER stops working. Explain how this problem could also affect the Golgi apparatus and the rest of the cell.
Materials would not move properly to the Golgi apparatus, so they could not be packaged or shipped. This would interfere with the cell’s overall function.
Why can the failure of one organelle affect the entire cell?
Organelles depend on one another. When one organelle cannot perform its function, other processes are interrupted, and the whole cell may malfunction or die.
A model shows the following sequence:
Nucleus gives instructions → ER moves materials → Golgi packages materials → Cell membrane controls what leaves
What does this model best demonstrate?
A. Only the nucleus is necessary.
B. Organelles perform unrelated jobs.
C. Organelles work together as a system.
D. Plant cells do not need mitochondria.
C. Organelles work together as a system.
