Study Notes
Section 1: Mitosis and its Function
- Mitosis is a cell division process that creates two new cells with exact copies of DNA from the original cell.
- Mitosis is used to produce more cells for growth and repair in multicellular organisms, and for asexual reproduction in single-celled organisms.
Mitosis for Growth and Repair
- Mitosis is the process by which body cells reproduce.
- It is essential for tissue growth, repair of damaged tissues and maintenance of organs in the human body.
Mitosis vs Meiosis
- Mitosis: Creates identical cells for growth, repair, and asexual reproduction
- Meiosis: Creates diverse cells that are required for sexual reproduction
- The number of chromosomes remains the same in mitosis, but it reduces to half in meiosis.
Role of Mitosis in Cell Growth
- One of the functions of mitosis is to make new cells for the growth of multicellular organisms.
- These new cells can repair damaged tissues in a wide variety of organisms
- All of the processes use mitosis
Turtle Growth
- The number of cells in a turtle increases, which causes the turtle to grow bigger.
- Increased size is due to cellular replication and growth of the overall organism.
Section 2: Cell Reproduction and Healing
- Cell reproduction increases during healing to promote faster healing of the wound.
- Higher rate of cell reproduction promotes faster and more efficient healing.
- Mitosis is the primary cell division process involved in tissue repair.
Meiosis and the Number of Cells
- In meiosis, the number of chromosomes is reduced by half to ensure the genetic combination of offspring.
- The daughter cells resulting from meiosis contain half the number of chromosomes of the parent cell
Meiosis and Sexual Reproduction
- Meiosis produces sex cells (gametes), needed for sexual reproduction.
- Meiosis enables the combination of genetic material from both parents to create a unique offspring.
- The diversity generated by genetic combination is key to adapting to environmental changes.
Differences between Mitosis and Meiosis
- Mitosis produces identical cells for growth and repair.
- Meiosis produces diverse cells used for sexual reproduction.
Chromosome Pairing
- Chromosomes exist in pairs because each pair comes from one parent.
- Each pair carries half the complete set of genetic information for the organism.
Types of Reproduction
- Sexual reproduction: Combining genetic material from two parents
- Asexual reproduction: Creating an exact copy of a single parent
Sexual Reproduction in Daffodils
- Daffodils reproduce sexually and asexually.
- Sexual reproduction combines genetic material from the female and male parent.
- Asexual reproduction creates new plants genetically identical to the parent plant.
Advantages of Sexual Reproduction
- Offspring inherit a wide array of genetic information from both parents.
- This diversity helps organisms survive and adapt to changing environments.
Other Key Concepts
- The cells produced from meiosis are not genetically identical to the parent cell
- Asexual reproduction results in offspring that are genetically identical to the parent
- When two sex cells merge during sexual reproduction, the resultant zygote will inherit genetic traits from both parents.
- Genetic variation arises as a result of sexual reproduction.
- Genetic combination of traits from parents produces a new organism with unique characteristics.
