Question

Why red blood cell and root hair cells both have large surface areas.

Answer 1

bc Contain haemoglobin to carry oxygen to the cells. Thin outer membrane to let oxygen diffuse through easily. Shape increases the surface area to allow more oxygen to be absorbed efficiently. No nucleus, so the whole cell is full of haemoglobin.

Answer 2

red blood cell contains hameoglobon to carry oxygen to the cells.the outer membrane to let oxygen diffuse through easily.shape increases the surface area to allow more oxygen to be absored efficently.where root hairs have large areas to ensure that water molecules diffuse completely in the roots.
