Study Notes

Cell Division

Cell division is the mechanism by which a parent cell splits into two or more daughter cells.
Mitosis generates two daughter cells, each with an identical chromosome number to the parent cell.
Meiosis results in gametes (sex cells) that contain half the chromosome count of the parent cell, facilitating sexual reproduction.

Cell Structure

Cells represent the fundamental building blocks of all living organisms, responsible for both structure and function.
Key organelles include:
- Nucleus: houses genetic material and regulates cell activities.
- Mitochondria: known as the powerhouse of the cell, generates energy through cellular respiration.
- Cytoplasm: gel-like substance where organelles are suspended and metabolic processes occur.
The cell membrane encases the cell, controlling the entry and exit of substances, thus maintaining homeostasis.

Cell Transport

Cell transport involves the movement of ions and molecules across the cell membrane, crucial for maintaining cellular function.
Two primary transport types:
- Passive transport: substances move across the membrane without energy expenditure, utilizing processes like diffusion and osmosis.
- Active transport: requires energy (ATP) to move substances against their concentration gradient, facilitated by specific transport proteins in the cell membrane.

Conclusion

Understanding cell division, structure, and transport allows Year 9 students to appreciate the complexities and functionalities inherent in living organisms.
