Cell Reproduction

QuestionAnswer
Why are chromosomes copied before cell division? So each new cell gets a full set of DNA.
How do cells control the cell cycle? Checkpoints, cyclins, and signals that stop or start division.
What is cancer, and what three changes happen in malignant cells? Cancer = uncontrolled cell division. Malignant cells: Divide uncontrollably, Look abnormal, Spread to other tissues.
Why do some cells live longer or shorter? Different jobs, different wear, and some divide often while others don’t.
Why do cells need to divide? For growth, repair, replacing old cells, and reproduction (in single‑celled organisms).
If a cell is damaged and can’t divide, what happens? Tissues can’t repair, and the area may weaken or lose function.
What happens to chromosome number from interphase to the end of division? DNA doubles in interphase, but the final two cells end with the same diploid number as the original.
How is cell division different in plant vs. animal cells? Animals form a cleavage furrow; plants form a cell plate.
Oncogene: Gene that causes uncontrolled division when mutated.
Tumor: Mass of abnormal cells.
Metastasis: Cancer spreading to new places.
Neoplasm: Another word for a tumor.
Malignant: Cancerous and able to spread.
