way it communicates. The defense mechanisms of the Bobois are especially unique. During the winter the Bobois produces a thick coat of gray slime that will cover its body to create a slimy shell. This slime protects it from cold temperatures by using the Greenhouse Effect to absorb and trap heat inside of the slime. When the season changes to Summer the slime will start to melt revealing its damp cyan-ish body which helps the worm keep cool during hot weather. Bibi Bobois’ are abnormally flat compared

and immediately it started to freeze. The polymer also started to flatten out. When it was taken out of the ice it was very slippery and hard to grip. It was also difficult to roll into a ball. But‚ after it sat in room temperature it was easier to mold into a ball and still carried the “bounce” that a bouncy ball should have.

Robert Hooke in 1665. It is not an entirely rigid structure as the cell wall expands due to the growth of the cell. It varies in thickness from o.1mm to I0mm.in most of the cells‚ cell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes) cell wall is present for a very short time. The cell wall is made of different materials depending on cell type. Only plant cell walls have cellulose which is an unbranched polysaccharide of D-Glucose linked together by p - 1-4
