Question
Chapter 4, Problem 3TY
Summary Introduction
Introduction: Living organisms consist of cells and almost all cells are small in size. The large sized organisms have more number of cells instead of having larger cells. Cells are small in size so that the amount of nutrient uptake and waste export through the plasma membrane can be decreased. A cell should have an appropriate surface area to volume ration in order to sustain.
