Organelles
This organelle controls the cell and contains DNA
What is the nucleus?
This is the stage of the cell cycle where the cell prepares for division.
What is interphase?
This is the process that produces two genetically identical cells.
What is mitosis?
This is controlled, programmed cell death.
What is apoptosis?
This imaging technique is best for bones.
What is an X-ray?
This organelle is responsible for producing energy (ATP) in the cell.
What is the mitochondria?
During this phase, the cell grows and produces proteins and organelles.
What is G1 phase?
In this phase, chromosomes line up in the middle of the cell.
What is metaphase?
This type of cell death occurs due to injury or damage.
What is necrosis?
This imaging technique uses sound waves.
What is an ultrasound?
This organelle modifies, sorts, and packages proteins for transport.
What is the Golgi apparatus?
During this phase, DNA is copied.
What is the S phase?
In this phase, chromosomes are pulled apart to opposite ends of the cell.
What is anaphase?
A cell ignores signals to stop dividing and does not undergo apoptosis. What type of cell is this becoming?
What is a cancer cell?
A doctor needs a detailed 3D image of a patient’s internal organs. Which imaging technique would be most appropriate?
What is a CT scan?
This organelle contains digestive enzymes and breaks down waste materials.
What is the lysosome?
During this phase, the cell prepares structures needed for division.
What is G2 phase?
Mitosis is necessary for these three bodily processes.
What is cell growth, development and repair.
Why are malignant tumours more dangerous than benign tumours?
What is: they can spread to other parts of the body (metastasize)?
Why is MRI better than X-ray for imaging soft tissues like the brain?
What is: MRI uses magnetic fields and can show soft tissue detail, while X-rays mainly show dense structures like bone?
A toxin prevents materials from entering and leaving the cell properly. Which structure is directly affected, and why?
What is the cell membrane?
These are the identical copies of a chromosome formed during DNA replication.
What are sister chromatids?
In a sample of 100 cells, approximately 85 are found in this phase of the cell cycle.
What is interphase?
Mutations caused by UV light lead to uncontrolled cell division. Explain how this results in cancer.
What is: mutations change DNA that controls the cell cycle, causing cells to divide uncontrollably?
A patient is given a radioactive substance to detect abnormal cell activity. Which imaging technique is being used and why is it useful?
What is a PET scan? (it highlights active/metabolic cells like cancer cells)
