Animal Cell vs. Human Cell: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 31, 2023
Animal cells are the basic unit of life in organisms of the kingdom Animalia, having a variety of forms and functions, while human cells are specific animal cells with characteristics unique to humans, like specific protein markers.
Key Differences
Animal cells vary widely in shape and function, adapted to the needs of different species, from nerve cells in birds to muscle cells in mammals. Human cells, a subset of animal cells, are specialized for functions unique to the human body, like neurons in the brain or cardiomyocytes in the heart.
The size of animal cells can range significantly, from tiny cells in microscopic organisms to larger cells in larger animals. Human cells are generally consistent in size, fitting within a range specific to humans, adapted to support human body functions.
Animal cells across different species can have a variety of surface markers and proteins, which differ based on evolutionary paths. Human cells have specific surface markers like human leukocyte antigens (HLAs), crucial for immune system functioning.
The genetic material in animal cells varies greatly, with different numbers of chromosomes and genetic sequences across species. Human cells contain 46 chromosomes, with a genetic makeup unique to the human species.
In terms of cellular metabolism, animal cells can have different metabolic pathways adapted to their ecological niches. Human cells have metabolic processes optimized for human physiology, like brain cells using glucose for energy.
