Because many plants have a "wax like" coating on the leaves for protection. If you destroy this protective coating, you destroy the plant's defense mechanism...... Also, you can induce other chemicals that can now be absorbed and kill the plant. Most herbicides are a combination of the two.

Biology has become such a vast research enterprise that it is not generally regarded as a single discipline, but as a number of clustered sub-disciplines. This article considers four broad groupings. The first group consists of those disciplines that study the basic structures of living systems: cells, genes etc.; the second group considers the operation of these structures at the level of tissues, organs, and bodies; the third group considers organisms and their histories; the final constellation of disciplines focuses on their interactions. It is important to note, however, that these boundaries, groupings, and descriptions are a simplified characterization of biological research. In reality, the boundaries between disciplines are fluid, and most disciplines frequently borrow techniques from each other. For example, evolutionary biology leans heavily on techniques from molecular biology to determine DNA sequences, which assist in understanding the genetic variation of a population; and physiology borrows extensively from cell biology in describing the function of organ systems.

Hi!\nI change my field of study from physics to biophysics but still its a great pleasure to solve a problem in physics if you dont mind.\nWish to see your project.\nBye

Hard question to answer.  i seem to remember a professor talking on this very subject so i will try and do him justice.\n\n1) surface tension of the phosopholipid bilayer cannot remain bound together once a cell reaches a certain size. another factor is genetic. the genome (depending on the cell type) has a pre determined size. once it is reache a phenominon called apoptosis or cellular suicide is activated bringing a wierd meaning to the welfare of the many outways the welfare of the one. anther aspect is environment.  depending on the cell and the environment it finds itself in, it must compete for for food.  larger cells need more food.  If the food source of the environment is scarce then it wil die as a result of starvation.  in biologic systems immune resppnse may play a significant factor in making the environment too hostile for life.  However lare single cell organisms do exsist.  I will not hand you the answer but I will give you a hint.  Look to Marine life..  good question!

Go here and look under 'A' for amoeba or use that search word:\n\nhttp://users.rcn.com/jkimball.ma.ultranet/BiologyPages/

hey! read a fish book. they always how a diagram of disecting parts or body anatomys. hint: for more info... go to this website:

The above is not complete. Don't have time to go into details, but check out this website:\n\nhttp://www.learner.org/channel/courses/biology/textbook/cancer/index.html\n\nI suggest reading the entire chapter if you don't have time for that, I suggest the section on Tumor Biology and the treatment section

In the textbook you got the question out of. Read it! LOL
