Cytokinesis

I scanned chapter questions that include diagrams from my text book. Please assist. Cytokinesis - the actual process of cell division - has attracted theorists for well over 100 years. Indeed, it has been said that all possible explanations of cytokinesis have been proposed... (please see attached).

What ingredients are needed for bread to rise?

Bread ingredients include milk, sugar, flour and salt. Which of these is needed for maximum fermentation by the yeast? What tests could be done in the lab? Will yeast react differently with different amounts of the other ingrediants? We did the lab and cut down the amounts of sugar, salt and milk. We had different results but do not know exactly why it happened. What reacted with what to form more corbon dioxide to make the dough rise more. What produced lactate, and what did the sugar react with the yeast or something elese?

What is the most important cell organelle?

Immune System Functionality and the Plasma Membrane

The integrity of the plasma membrane is essential for cellular survival. a. Could the immune system utilize this fact to destroy foreign cells that have invaded the body? b. How might cells of the immune system disrupt membranes of foreign cells?

Can a Cell Live without a Cytoskeleton?

"In one simple experiment, a nucleus was removed from an amoeba. The amoeba stopped dividing and died within a few days. But, if a new nucleus was implanted, the single celled animal lived and divided normally. This early experiment let researchers know that the nucleus was essential for life of the cell, and for cell division. In fact, such experimental findings underlie the fields of cell biology, genetics and molecular biology, (Cram, 1999)". the quote is fromrom: Cram, E. (1999, January 7). How exactly does the nucleus of a cell control everything?
