BIO 181 - Chapter 1 and 2Describe the three components of Cell Theory - correct answer 1. All living organisms are composed of one or more cells 2. Cells are the smallest units of life 3. New cells come only from pre-existing cells by cell division Identify the basic features of cells - correct answer Plasma membrane, cytoplasm, nucleoid, ribosomes, cell wall, glycocalyx, pili, flagella Explain how the surface area to volume ratio changes as cells change in size and explain the benefits for the cells of maximizing surface area to volume ratio (look at cell size worksheet from week 1) - correct answer -As cell gets larger, the SA/V ratio gets smaller -The higher the surface area to volume ratio they have, the more effective this process can be. Describe the structure and function of the cell components in a prokaryotic cell - correct answer -lack membrane enclosed nucleus and compartmentalization -all members of the domains bacteria and archaea Describe the structure and function of the cell components in a eukaryotic cell - correct answer -cytosol outside the membrane- bound organelles but inside the plasma membrane -all members of the domains plant and animal Describe the relationship between structure and function - correct answer -the structure is the backbone of the cell -the function is the roles each part of the cell plays Describe the difference between cytosol and cytoplasm in a eukaryotic cell - correct answer -cytosol: the region of a eukaryotic cell that is inside the plasma membrane and outside the organelles
