Question

Generally prokaryotic cells and eukaryotic cells only differ in size by about a factor of 10. The upper limit to the size of a cell is largely determined by . Smaller cells in comparison to larger cells have a ratio of surface area to volume. The larger the surface area of a cell, the is the exchange of molecules across the cell boundary.

Answer 1

Prokaryotic cells and eukaryotic cells differ not just in size but also in structure and complexity. The small size of prokaryotic cells allows for efficient exchange of ions and molecules. Eukaryotic cells have developed adaptations to overcome the limitations imposed by their larger size.

Step-by-step explanation:

In general, prokaryotic cells and eukaryotic cells differ not just in size but also in structure and complexity. Prokaryotic cells are smaller, ranging from 0.1-5.0 μm in diameter, while eukaryotic cells are larger, ranging from 10-100 μm in diameter. The small size of prokaryotic cells allows for efficient exchange of ions and molecules, as they can quickly diffuse to other parts of the cell. On the other hand, larger eukaryotic cells have developed various adaptations to enhance intracellular transport and overcome the limitations imposed by their size.

Answer 2

The correct answer would be - a) surface area to volume ratio

b) As the cell size increases, the surface area to volume ratio decreases

c) The higher/larger is the surface area, the more is the exchange of ions across the membrane

Step-by-step explanation:

Prokaryotic cells are normally smaller than the eukaryotic cells about a factor of 10, normally the prokaryotic cells range from 0.1 to - 5 µm in diameter such while the 10 to 100 µm in diameter.

The upper limit to the size of a cell is determined by the surface area to volume ratio of the cell. Increase in the cell size the ratio of surface area to volume decreases. The higher the surface area of the cell the more is the transport or movement of the ions across the membrane.

Thus, the correct answer is - a) surface area to volume ratio

b) As the cell size increases, the surface area to volume ratio decreases

c) The higher/larger is the surface area, the more is the exchange of ions across the membrane.
