If a particular cell is known to be round and incapable of producing its own food, which one of these organelles would you assum
UNO [17]

If a particular cell is known to be round and incapable of producing its own food, such a cell would not be a plant cell. As such, from the options below:

  • <em>CENTRAL VACUOLE </em>
  • <em>plasma membrane </em>
  • <em> cell wall </em>
  • <em> chloroplast</em>

The correct answer as to which of the organelles the cell must have would be the plasma membrane.

  • central vacuole, cell wall, and chloroplast are all characteristic of plant cells.
  • All cell types have plasma membrane.

Hence, since it has been established that the cell is not a plant cell, the only organelle left that the cell cannot do without is the plasma membrane.
