You can tell the age of a yeast cell by (a) counting scars.
Yeast is a unicellular eukaryotic organism. It belongs to the kingdom Fungi. It is primarily used in baking, cooking and in alcohol industries as well. There are various strains of yeast and the most widely used one is <em>Saccharomyces cerevisiae</em>, also called the baker's or the brewer's yeast.
Scars on the yeast are actually the bud scars formed due to budding. Budding is the process by which the yeast reproduces and gives rise to its offspring. Hence every time a daughter bud pinches off from the yeast cell, a scar is formed.

Because cell is composed of organelle and several little material which haven't an ability to increase in size just in same manner as a rubber therefore cell divide for increase their number .
i hope this is helpful
A. They produce carbon dioxide<span> for food it includes both so it would be more correct

I believe that local controls are what causes reactive hyperemia to increase tissue perfusion. Reactive hyperemia or venous hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischaemia.
Tissue perfusion is the decrease in oxygen resulting in the failure to nourish the tissues at the capillary level. Local blood flow regulation involves the rapid control of arterial vasomotion based on the metabolic needs of the surrounding tissues and cells.
