Study Notes
Mitosis
- Mitosis is a cell division process resulting in two identical daughter cells.
- Essential for growth, healing, and tissue replacement.
- In humans, each diploid cell contains 46 chromosomes post-mitosis.
- Chromosomes consist of DNA and protein.
- Mitosis is a small part of the cell cycle, representing about 10% of it.
Types of Cells
- Somatic cells undergo mitosis.
- Sperm and egg cells do not undergo mitosis.
Stages of Mitosis
- Prophase: Chromosomes condense and become visible.
- Metaphase: Chromosomes align in the middle of the cell; the nucleus disassembles.
- Anaphase: Chromosomes move away from each other, assisted by spindle fibers.
- Telophase: Two nuclear membranes form around separated chromosomes.
- Cytokinesis: Cell splits into two daughter cells.
Asexual and Sexual Reproduction
- Asexual reproduction involves one organism, resulting in clones.
- Sexual reproduction requires two organisms contributing genetic material.
- Organisms like starfish and strawberries can reproduce both ways.
- Asexual reproduction is faster and does not require finding a mate.
- Disadvantages of asexual reproduction include vulnerability to diseases.
- Advantages of sexual reproduction include genetic diversity and adaptive potential.
Specific Features of Reproduction
- In sexual reproduction, the female reproductive cell is the egg, and the male is the sperm.
- Offspring from asexual reproduction are identical to the parent.
- Male cells determine offspring gender in sexual reproduction.
Advantages and Disadvantages
- Asexual reproduction permits rapid reproduction without a mate.
- Sexual reproduction enables adaptation to environmental changes but is slower and requires mate interaction.
Unique Reproductive Methods
- Fission: Parent splits into two offspring.
- Budding: Offspring grows on the parent and detaches when mature.
- Vegetative reproduction: Cutting from a plant develops into a new individual.
- Parthenogenesis: Egg develops into offspring without fertilization.
Biological Functions
- Respiration involves energy release, while nutrition encompasses food intake and processing.
- Digestion refers to the breakdown of food for energy.
