Morphology vs. Physiology: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 12, 2024
Morphology studies the form and structure of organisms, while physiology examines their functions and processes.

Key Differences

Morphology is the branch of biology that deals with the form and structure of organisms, including their size, shape, and structure. Physiology focuses on the functions and processes of the various systems within organisms.
Morphologists study the external and internal structures, such as bones and muscles. Physiologists analyze how these structures function, such as how muscles contract or how the heart pumps blood.
Morphology provides insights into how organisms evolved and adapted physically. Physiology helps in understanding how these adaptations function to support life processes.
Morphological research often involves dissection and microscopy to observe structures. Physiological studies typically involve experiments to observe functions, such as monitoring heart rate or brain activity.
Morphology is closely related to anatomy and taxonomy. Physiology intersects with biochemistry and medicine in understanding how bodily systems operate and respond to changes.

Can physiology be applied to plant studies?

Yes, plant physiology studies functions like photosynthesis in plants.

Can morphology reveal evolutionary history?

Yes, morphology can provide clues about an organism's evolutionary adaptations.

Do morphologists study living or dead organisms?

Morphologists study both, examining structures of living and preserved specimens.

How does physiology relate to biochemistry?

Physiology overlaps with biochemistry in studying chemical processes in organisms.

Is human physiology different from animal physiology?

While there are similarities, human physiology has unique aspects compared to other animals.
