Question

Which of the following pairs show the relation between shape and function of cells?

• A. Long spindle shape of neuron- rely on electrical impulse all over the body
• B. Disc like shape of RBCs- allows blood to be squishy to transport gas and nutrients
• C. Intestinal cell covered with cilia- increase surface area for more absorption of nutrients
• D. All of the above

Answer 1

Answer: (D)

All of the above

• An axon or nerve fiber, is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses .
• Red blood cells transport oxygen around the body. They are specialised to carry oxygen because they have a biconcave disc shape, which maximises the surface.
  
• Microvilli are hair that aid in absorption of nutrients. ... In the small intestine, these cells contain microvilli, which are tiny hair-like projections that increase nutrient absorption.
