In this article, we will explore the reasons behind the small size of cells, the implications of their size for their functions, and how these factors contribute to the complexity of . Explanation 2:The rate of diffusion is related to cell size. Membranes are phospholipid bilayers containing embedded proteins; the phospholipid fatty acids limit the movement of water because of their hydrophobic characteristics. Dec 14, 2022 · Most cells are between 2 micrometers and 200 micrometers—too small to be seen with the naked eye. Nutrients diffuse at a faster rate through small cells than they do through large cells Key Definitions Diffusion: the movement of molecules in a gas or liquid to Sep 17, 2021 · Cell Size Lab Purpose: The purpose of this lab is to demonstrate cell size and how it is connected to the function of the cell.
