Questions and Answers
What is the primary function of interphase in the cell cycle?
What is the primary function of interphase in the cell cycle?
- DNA is replicated. (correct)
- Location of organelles is determined.
- Cell division occurs.
- The cell undergoes differentiation.
What defines the difference between haploid and diploid cells?
What defines the difference between haploid and diploid cells?
- Haploid cells are found only in somatic cells; diploid cells are found in gametes.
- Haploid cells have two sets of chromosomes; diploid cells have one set.
- Diploid cells have two sets of chromosomes; haploid cells have one set. (correct)
- Diploid cells are produced by mitosis; haploid cells are produced by meiosis.
Which of the following best describes the importance of mitosis?
Which of the following best describes the importance of mitosis?
- It initiates cellular differentiation.
- It facilitates the fusion of cells.
- It produces gametes for sexual reproduction.
- It helps maintain the genetic stability of cells. (correct)

Study Notes
Cell Cycle in Eukaryotes
- The human body contains trillions of cells
- Around 330 billion new cells are produced daily (approximately 3.8 million per second)
- This study focuses on the eukaryotic cell cycle
- The cell cycle describes the growth and development of a cell
- DNA replication is protected within the cell nucleus to maintain genetic identity, preventing cancer.
Learning Objectives
- Explain the cell cycle and cell division process
- Define haploid and diploid cells
- Describe mitosis and meiosis
- Discuss the importance of mitosis and meiosis
Phases of the Eukaryotic Cell Cycle
- Complex cells, including Golgi apparatus and nucleus
- Growth and development occur at a cellular level
- Cell division is called the cell cycle
- The cell cycle consists of two phases:
- Interphase: cell growth, DNA replication
- Cell division: the cell splits into two.
Interphase
- Preparation for cell division
- DNA replication occurs
- The cell grows
Cell Division
- The cell divides into two identical daughter cells.
- The duration of the cell cycle varies based on the organism and cell type
- Cells in rapidly dividing tissues, like skin, divide more quickly than cells in other tissues
- Example cell cycles: skin cells divide every 12-20 hours, skeletal cells 10 years, nerve cells as long as the individual.
