Chapter 3, Problem 6Q
Summary Introduction
To determine:
The reasons for the similarities between bacteria and eukaryotic cells that are radically different organisms.
Introduction:
Bacteria are prokaryotes, which have no organelles. They are single-celled organisms. Their cell wall has peptidoglycan and they reproduce by binary fission. The bacteria included in prokaryotes, are unicellular organisms without a nucleus and their chromosomes are condensed in the cytoplasm. They contain ribosomes of 70S type.
Eukaryotes can be distinguished from other organisms, because they contain a eukaryotic cell with true nucleus. There are limited numbers of sources of carbon and energy that are able for eukaryotes and they can reproduce sexually. Evolution would be occur in eukaryotes intheir gene regulation patterns, cell shape, and cell types that can further interact for their growth and development.
