Explanation:

• Task 1:
• 1. The nucleus is the control center of the cell as it contains the cell's genetic material (DNA) which regulates cellular activities.

• 3. Smooth endoplasmic reticulum is involved in lipid synthesis.
• 4. Mitochondria are the power - houses of the cell, generating ATP through cellular respiration.
• 5. The cell membrane (plasma membrane) controls the movement of substances in and out of the cell.
• 6. The cytoplasm is composed of cytosol and organelles (excluding the nucleus).
• 7. The Golgi apparatus modifies, sorts, and packages proteins for secretion.
• 8. Lysosomes are membrane - bound organelles with digestive enzymes.
• 9. Nuclear pores are channels in the nuclear membrane for substance movement.
• 10. Endocytosis is the process of bringing materials into the cell.
• 11. The cytoskeleton gives the cell its shape.
• 12. The plural of flagellum is flagella.
• 13. Cilia are hair - like structures on the cell membrane.
• Task 2:
• 1: Nucleus (contains genetic material)
• 2: Nucleolus (site of ribosome synthesis)
• 3: Chromatin (DNA in non - condensed form)

• 9: Vesicle (transport of materials)
• 10: Microfilament (part of the cytoskeleton)
• 11: Rough endoplasmic reticulum (another view of the same structure)
• 12: Vesicle (another vesicle)
• 13: Smooth endoplasmic reticulum (lipid synthesis)
• 14: Centrosome (contains centrioles)
• 15: Cytoplasm (contains cytosol and organelles)
• 16: Microtubule (part of the cytoskeleton)
• 17: Mitochondrion (ATP production)
• 18: Intermediate filament (part of the cytoskeleton)
