Discuss the major features of bacteria cell giving an example of an organism bearing it.
Answers
Answer:
The bacterium, despite its simplicity, contains a well-developed cell structure which is responsible for some of its unique biological structures and pathogenicity. Many structural features are unique to bacteria and are not found among archaea or eukaryotes. Because of the simplicity of bacteria relative to larger organisms and the ease with which they can be manipulated experimentally, the cell structure of bacteria has been well studied, revealing many biochemical principles that have been subsequently applied to other organisms.
Explanation:
Characteristics of Bacteria
Bacteria are the most successful organisms on the planet. They lived on this planet for two billion years before the first eukaryotes and, during that time, evolved into millions of different species.
Size and Shape
Bacteria are so small that they can only be seen with a microscope. When viewed under the microscope, they have three distinct shapes (Figure below). Bacteria can be identified and classified by their shape:
Bacilli are rod-shaped.
Cocci are sphere-shaped.
Spirilli are spiral-shaped.
Drawing of rod, sphere, and spiral shaped bacteria
Bacteria come in many different shapes. Some of the most common shapes are bacilli (rods), cocci (spheres), and spirilli (spirals). Bacteria can be identified and classified by their shape.
Answer:
Bacteria are individual living cells. Bacteria cells are similar to your cells in many ways; yet, they also have distinct differences.
- They don't have a nucleus.
- They also lack membrane-bound organelles.
- Bacteria are surrounded by a cell wall .
- Some bacteria also have tail-like structures called flagella.
