period 5th
below is a chart of cell types and the number of cell organelles found within each one.
organelle # per pancreatic cell # per macrophage # per muscle cell # per leaf cell # per bacterium
ribosome 5,000,000 1,500,000 1,000,000 1,000,000 25,000
mitochondria 1,500 1,000 3,000 1,000 0
chloroplast 0 0 0 50 0
lysosome 1,200 5,000 800 0 0

1. which cell (pancreatic, macrophage, muscle cell, leaf cell, or bacterium) would be best as a solar power plant? why?
2. which cell (pancreatic, macrophage, muscle cell, leaf cell, or bacterium) would be best at product (protein) production? why?
3. which cell (pancreatic, macrophage, muscle cell, leaf cell, or bacterium) would be best at cleaning up cellular wastes? why?
4. which cell (pancreatic, macrophage, muscle cell, leaf cell, or bacterium) would be best at generating power? why?

Explanation:

Step1: Identify organelle for solar - power conversion

Chloroplasts are the organelles responsible for photosynthesis, which converts sunlight into energy.

Step2: Find cell with most chloroplasts

From the table, leaf cells have 1,000 chloroplasts, which is the highest among the given cell types. So, leaf cells are best as a solar - power plant.

Step3: Identify organelle for protein production

Ribosomes are the sites of protein synthesis.

Step4: Find cell with most ribosomes

Pancreatic cells have 5,000,000 ribosomes, the highest number among the given cells, making them best at protein production.

Step5: Identify organelle for waste - cleaning

Lysosomes break down cellular waste.

Step6: Find cell with most lysosomes

Macrophages have 5,000 lysosomes, the highest number, so they are best at cleaning up cellular wastes.

Step7: Identify organelle for power generation

Mitochondria are the power - houses of the cell, generating ATP.

Step8: Find cell with most mitochondria

Muscle cells have 3,000 mitochondria, the highest number among the given cells, so they are best at generating power.

Answer:

1. Leaf cell because it has chloroplasts for photosynthesis.
2. Pancreatic cell because it has the most ribosomes for protein synthesis.
3. Macrophage because it has the most lysosomes for waste - breakdown.
4. Muscle cell because it has the most mitochondria for power generation.
