  • B
    Elongated or branched.
  • C
    With large surface area.
  • D
    Having microvilli.
✓

Answer

  1. Elongated.

Explanation:

  • Generally, cells are small so they can have an efficient surface area to volume ratio. Cells are so small so they can diffuse faster and all their processes will be a lot faster because of the smaller size of the cell.
  • For the large sized cells to become Efficient the cells must be elongated in order to have an efficient surface area to volume ratio.
  • Hence efficient large-sized cells are elongated.
