The video tutorial explains the cell cycle, highlighting its role in reproduction, growth, development, and tissue renewal. It details the stages of interphase, mitosis, and meiosis, emphasizing the differences between mitosis in somatic cells and meiosis in gametes. Mitosis results in two identical daughter cells, while meiosis produces four genetically diverse haploid cells.

What percentage of its life does a cell typically spend in interphase?

• 75%

• 50%

• 10%

• 90%

Which stage of mitosis involves the condensation of chromatin into chromosomes?

• Metaphase

• Telophase

• Prophase

• Anaphase

During which phase do the chromosomes line up on the metaphase plate?

• Metaphase

• Prophase

• Anaphase

• Telophase

What structure is responsible for pulling the sister chromatids apart during mitosis?

• Chromatin

• Nuclear membrane

• Mitotic spindles

• Centrioles

What is the main difference between cytokinesis in plant cells and animal cells?

• Cleavage furrow formation

• Spindle fiber formation

• Cell plate formation

• Chromosome duplication

What is formed at the cleavage furrow during cytokinesis in animal cells?

• Spindle fibers

• A new nucleus

• Two daughter cells

• A cell plate

How many daughter cells are formed at the end of meiosis I?

• Eight

• Four

• One

• Two

During which stage of meiosis are homologous chromosomes separated?

• Telophase

• Meiosis I

• Prophase

• Meiosis II

What is the result of meiosis in terms of the genetic identity of the daughter cells compared to the parent cell?

• Twice the genetic material

• Not identical

• Half identical

• Identical

Which of the following is a stage unique to meiosis and not observed in mitosis?

• Anaphase II

• Interphase

• Metaphase

• Cytokinesis
