In the context of cell biology, what do we mean by form follows function? What are at least two examples of this concept?

Question: What is the concept of "form follows function" in cell biology, and provide two examples illustrating this concept. Answer: The concept of "form follows function" in cell biology refers to the idea that the structure or shape of a biological molecule or organism is directly related to its purpose or role in living systems. Structures have evolved to perform their intended functions more efficiently or effectively. Two examples illustrating this concept are red blood cells and neurons. Red blood cells have a biconcave disc shape with a large surface area-to-volume ratio, allowing for efficient gas exchange, and lack organelles to maximize space for oxygen-carrying hemoglobin. Neurons have long extensions called axons and dendrites, which help transmit electrical signals across distances, and synapses that enable communication between neurons, forming networks for complex functions like processing sensory information or coordinating muscle movements.
