Efficient large$-$sized cells are:
✓
Elongated.
B
Elongated or branched.
C
With large surface area.
D
Having microvilli.
✓
Answer
Correct option: A.
Elongated.
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.
