What can you learn from an essay on bacteria?
In this essay we will discuss about Bacteria. After reading this essay you will learn about:- 1. Meaning of Bacteria 2. Salient Features of Bacteria 3. Morphology 4. Cell Wall 5. Size 6. Flagellation 7. Behavioural Responses 8. Endospores 9. Reproduction 10.
How does bacterial morphology contribute to natural selection?
The simplest conclusion is that morphological adaptation serves an important biological function. How, then, might morphology contribute to natural selection? Simply put, bacteria with different shapes present different physical features to the outside world, and these features help cells cope with and adapt to external conditions.
What are the basic characteristics of a bacteria?
General Characters of Bacteria: 1. Bacteria are simple most primitive organisms. They are very minute in size ranging from 0.5 to 2 µ in size. 2. They show prokaryotic type of cell organization. 3. Majority of bacteria are simple unicellular organisms. 4. Because of the presence of rigid and definite cell wall, they are considered as plants.
Why are archaea similar to bacteria in morphology?
So, for example, although they have a non-peptidoglycan-based cell wall, the Archaea exhibit a range of morphological forms similar to that of the Bacteria [12]. The simplest conclusion is that morphological adaptation serves an important biological function. How, then, might morphology contribute to natural selection?
