Cell Cycle and Division starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cell Cycle and Division.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A cell with 12 chromosomes undergoes mitosis. How many chromosomes will each daughter cell have?
A student observes a cell under a microscope and notices that the chromosomes are lined up in the middle of the cell. Which phase of mitosis is the cell in?
Describe one reason why cell division is important for multicellular organisms.
Describe what happens during the S phase of interphase.
During which phase of mitosis do the sister chromatids move toward opposite poles of the cell?
During which phase of the cell cycle does the cell check for DNA damage before proceeding to mitosis?
During which phase of the cell cycle does the cell grow and carry out normal functions?
A student observes a cell under a microscope and notices that the chromosomes are lined up in the middle of the cell. Which phase of mitosis is the cell in?

(1) G1 checkpoint
(2) G2 checkpoint
(3) M checkpoint
(4) S checkpoint
Which of the following best describes the difference between mitosis and meiosis?
