Understanding Mitosis and Meiosis

This video tutorial explores the processes of mitosis and meiosis, highlighting their similarities and differences. Mitosis results in two identical diploid body cells, while meiosis produces four non-identical haploid gametes. Both processes involve stages of interphase and PMAT (prophase, metaphase, anaphase, telophase). A key difference is the crossing over in meiosis, which increases genetic variation. The video concludes with a reminder of the importance of kindness.

What is the primary goal of both mitosis and meiosis?

• To destroy old cells

• To create new cells

• To repair damaged cells

• To create identical cells

What type of cells does mitosis create?

• Body cells

• Gametes

• Haploid cells

• Stem cells

What does it mean for a cell to be diploid?

• It has one set of chromosomes

• It has two sets of chromosomes

• It has three sets of chromosomes

• It has no chromosomes

During which phase do cells spend most of their time preparing for division?

• Metaphase

• Anaphase

• Prophase

• Interphase

What does PMAT stand for in cell division?

• Prophase, Metaphase, Anaphase, Termination

• Prophase, Mitosis, Anaphase, Telophase

• Prophase, Metaphase, Anaphase, Transition

• Prophase, Metaphase, Anaphase, Telophase

What unique process occurs during prophase in meiosis?

• Chromosome duplication

• DNA replication

• Cell division

• Crossing over

How do chromatids behave differently during anaphase in mitosis compared to meiosis?

• They remain stationary in mitosis

• They are pulled in the same direction in mitosis

• They are pulled apart in mitosis

• They are pulled together in mitosis

What is the result of mitosis after cytokinesis?

• Two non-identical cells

• Four non-identical cells

• Four identical cells

• Two identical cells

What type of cells are produced at the end of meiosis?

• Diploid cells

• Haploid gametes

• Identical cells

• Stem cells

How many chromosomes do human gametes have?

• 23 pairs

• 46 total

• 23 total

• 46 pairs
