1) Describe in detail about cell wall and nucleooid of bacterial cell, their structure and composition.

There exist two main kinds of cells: prokaryotic and eukaryotic. Bacterial cells are prokaryotic. Choose two structures of the bacterial cells and briefly explain them; what do they look like, what are they composed of? Then, describe how these two structures allow bacterial cells to survive as unicellular organisms.

2) Explain the difference between ionic and covalent bonds.

Define cell in your own words. Explain the two chief tenets of the cell theory? Explain the difference between the deuterostomes and protostomes? Among the living organisms, at least name one phylum example of each of these.
