The Prokaryotic Life is characterized by:
Correct answer: B. Absence of nuclear envelope
- A. Absence of locomotion
- B. Absence of nuclear envelope
- C. Absence of Protein
- D. Absence of nuclear material
Explanation
Prokaryotic life is characterized by the absence of a nucleus and membrane-bound organelles in the cells. Prokaryotic cells are typically smaller and simpler in structure than eukaryotic cells, and they contain a single, circular chromosome that is not enclosed in a nuclear membrane. Prokaryotic cells also lack other membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Instead, they have a cell wall, plasma membrane, and cytoplasm that contains ribosomes, which are responsible for protein synthesis. Prokaryotic cells can be divided into two main groups: bacteria and archaea. They are found in a wide range of environments, including soil, water, air, and the bodies of plants and animals. Prokaryotes play important roles in many ecological processes, such as nutrient cycling, decomposition, and symbiotic relationships with other organisms. They are also used in many biotechnological applications, such as genetic engineering, bioremediation, and food production.
