First, let's differentiate all the detailed vocabulary about all these cells we learned this week. When looking under microscope what structural differences would you see between two types of cells. Now choose ONE cellular component (e.g. a part of a cell) that is found only in bacteria. Discuss what its role is. -OR- Choose ONE cellular component that is only found in eukaryotes. Discuss what its role is.

Within a prokaryotic cell, bacteria, you will find peptidoglycan. This is a component only found in bacteria. The role of this compound, peptidoglycan, is to give bacteria its rigid structure within the cell wall. This is what protects certain substances from entering the bacteria, this sturdy wall provides support and strength to the bacteria. Peptidoglycan is composed of, to simplify, sugar and proteins that allow the cell wall of bacteria to be strong and bendy. Another reasons why peptidoglycan is...

43.Lipopolysaccharides (LPS) are found in: a. Gram-positive bacteria b. Gram-negative bacteria c. all Bacteria d. Archaea e. Eukaryotes ------------------------- 44. There are similarities and differences between Gram-negative and Gram-positive bacteria. Which of the following is not true? a. The cell wall of Gram-negative cells is composed of only one or two layers of peptidoglycan whereas the cell walls of Grampositive bacteria have many peptidoglycan layers b. Only Gram-positive bacterial cells have a periplasm 2/6/18 8 c. The cell membranes of...

2.4.5 Let the disk B2 have the cellular structure with t 0-cells, t 1-cells and one 2-cell. Compute the corresponding cellular chain complex and use it to compute the cellular homology of B2. This can be done over any field of coef- ficients, but you can choose to do the computation over F2 only. [If you know some group theory, you can view the matrices as homomorphisms betweern free abelian groups. You can then try to do the computation over...
