Chapter 4, Problem 3TYK
Summary Introduction
Introduction: The cells have different size as per their diameter and volume ratio.“Cell surface to volume ratio” is important to maintain the cell functions. A small sized cell have high surface area ratio. A high surface to volume ratio is good for the exchange of materials between the cell and its environment. Larger organism has more number of cells instead of large cells to facilitate the better exchange of materials.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
