Question

How does cell size and shape affect the overall rate of nutrient intake and the rate of waste elimination?

Answer 1

Hint: The cell is the basic structural, functional, and biological unit in all organisms. A cell is the smallest unit of life. Nutrients are food compounds that are important to life and health, which provide us with energy, repair and growth building blocks, and substances that are required to control chemical processes.

Complete answer:
We may generalize the shape of a cell as circular (spherical) or irregular, considering an animal cell. Plant cells are much more linear in shape and are rectangular. A cell can be six to twelve inches in height and as small as 0.0001 mm. There are two groups of cells: eukaryotic, which have a nucleus, and prokaryotic, which does not have a nucleus. Prokaryotes are single-celled species, whereas eukaryotes can be single-celled or multicellular eukaryotes. For larger cells, because of the larger distance that must be covered by the same transport processes as those taking place in smaller cells, nutrient absorption and waste removal takes a longer period. Shapes that optimize the surface area help increase the rate of absorption of nutrients and the removal of waste. To exchange materials effectively, the surface area must be large enough. The smaller the cell, the more favorable the ratio of volume to surface area for material exchange with the atmosphere is done by diffusion. Although surface area determines the rate at which nutrients are taken in or excreted, the volume determines how much enters and leaves the cell. Volume grows faster than the surface area, the rate at which nutrients can be taken in and waste is not rapid enough to satisfy the cell size.
Therefore, size and shape of the cell affect the overall rate of nutrient intake and the rate of waste elimination.

Note:
A cell's shape can influence its surface area. A cell's surface area determines how much contact the cell is going to have with its surroundings. The functioning of the cell is dependent on the size and shape of the cell.
