Question

1. the model shows the relationship between surface area and volume in cells.

describe how the surface area to volume ratio affects the health of a cell.

explain why cells function better as smaller units.

Explanation:

A higher surface - area - to - volume ratio allows for more efficient exchange of materials (such as nutrients and waste) across the cell membrane. As a cell grows, its volume increases faster than its surface area. Smaller cells have a relatively larger surface area compared to their volume. This means they can more easily take in nutrients (e.g., glucose, oxygen) and expel waste (e.g., carbon dioxide) through the cell membrane. Larger cells would have difficulty meeting their metabolic demands in terms of material exchange because the surface area would be insufficient relative to the volume.

Answer:

• Describe how the surface Area To Volume ratio affects the health of a cell: A higher surface - area - to - volume ratio promotes better health as it enables efficient nutrient uptake and waste removal. A lower ratio (in larger cells) can lead to inefficiencies in these processes, potentially harming the cell.
• Explain why cells function better as smaller units: Smaller cells have a more favorable surface - area - to - volume ratio. This allows for quick and sufficient exchange of substances across the cell membrane to support the cell's metabolic activities.
