Question

Why do peroxisome from many different classes of organisms have different characteristics. Include the evolutionary aspects of the answer

Answer 1

Studies suggest that peroxisomes were acquired by the cell during Precambrian era that is almost 1.5 billion years ago in primitive eukaryotic cells to decompose hydrogen peroxides to save cell from the oxidizing stress. During the course of evolution as the primitive cell changed its form and evolved in the more advanced forms the types of stresses on cells also changed. On further evolution then different species came in existence cells underwent rapid evolutionary changes regarding the environmental condition, food and living need. And thus the internal composition of the cells also changes drastically from the primitive Precambrian cell, which needed more defined system for other metabolic process which resulted in specialization of peroxisomes species specifically.
