Structured William's model
P. can describe the changes in intracellular components of the cell during growth
Q. cannot describe the death phase of the cells
R. can describe the variation of size of cells in the different phases of growth
S. cannot describe the lag period of growth
Which one of the following is correct?
-
- P, Q and S only
- P, Q and R only
- Q, R and S only
- P, R and S only
Correct Option: B
Williams proposed a simple structured model that divides the biomass into two parts: Part 1 is composed of intermediates, enzymes, and other entities involved in the formation of materials used for synthesis of structural and genetic material; Part 2 is the structural and genetic part of the biomass. It can be used to describe the change in intracellular components during cell growth. In the different phases of cell growth, this model enables analytical depiction and explanation of the variation in the size of the cells. But the model is not structured for reasoning with the death phase of the cells.
