Current Question (ID: 12616)

Question:
Choose incorrect statement regarding cells
Options:
  • 1. Mycoplasma, the smallest cell, is only 0.3 μm in length while bacteria could be 3 to 5 μm
  • 2. Hemoglobin associated human cells are about 7 μm in diameter
  • 3. The shape of the cell may not vary with the function they perform
  • 4. Nerve cells are longest cells
Solution:
The shape of the cell is closely related to its function. Different cell types have different shapes that are adapted to their specialized functions. For example, red blood cells are biconcave disks that lack a nucleus, which allows them to carry oxygen more efficiently. Nerve cells, or neurons, have a long, thin shape that enables them to transmit electrical signals over long distances. Hemoglobin-associated human cells are Red blood cells which are about 7.0 μm in diameter.
