Final answer:
Cell structures are matched with descriptions: ribosomes make proteins, smooth ER synthesizes lipids, mitochondria produce energy, the nucleus contains DNA, the Golgi apparatus modifies and sorts proteins, lysosomes digest waste, centrioles aid in cell division, and the cytoskeleton maintains cell shape.
Step-by-step explanation:
To match each cell structure with the correct description, you can use the following information:
- 1. Ribosome: A cell structure that produces proteins.
- 2. Smooth ER: This is part of the endomembrane system and is responsible for lipid synthesis and detoxification processes.
- 3. Mitochondrion: Often referred to as the power plant of the cell, it generates energy in the form of ATP.
- 4. Nucleus: It contains the cell's genetic material and controls cell activities.
- 5. Golgi apparatus: It packages proteins for transport out of the cell.
- 6. Lysosome: An organelle that contains digestive enzymes to break down waste.
- 7. Centriole: A structure involved in cell division.
- 8. Cytoskeleton: Provides the cell with its shape and structure.
The ribosomes, rough endoplasmic reticulum (rough ER), and Golgi apparatus work together in protein synthesis. Ribosomes build the proteins, which are then transported to the Golgi apparatus via vesicles from the rough ER for modification and sorting.
Smooth ER differs from rough ER in that it lacks ribosomes on its surface and is involved in lipid metabolism, whereas rough ER has ribosomes and is involved in protein synthesis. The cytoskeleton consists of actin filaments, microtubules, and intermediate filaments, providing structural support and facilitating intracellular transport.
