Criteria for Biological Classification

Several criteria are used to classify organisms in biological classification:

• Morphology: The structure and form of organisms are analyzed, including aspects like size, shape, and arrangement of parts.
• Anatomy: The internal structure of organisms is studied, such as the arrangement of tissues and organs.
• Genetics: Genetic makeup, including DNA sequences, is examined to understand hereditary information and evolutionary relationships.
• Biochemistry: The chemical processes within and related to living organisms are considered, including metabolic pathways and enzyme functions.
• Embryology: The development process from fertilization to the mature form is observed to understand growth patterns and developmental stages.
• Ecology: The relationship of organisms with their environment and other living beings is also taken into account.
