List two examples of how cells' shapes are suited to their functions?

Answer:

Red blood cell in humans - it has no nucleus. Hence it offers the cell to carry more haemoglobin.

- they are disc shaped allowing them to pass through narrow capillaries.

Root hair cells in plants- they have a large cytoplasm which enables them to take water from the soil.

White Blood Cells in humans - they have lobed nucleus and so can change their shape to pass through narrow capillaries.
