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.
