The shape of the nucleus is lens shaped in the onion cell structure

Explanation:

  • The lens-shaped nucleus in this cell is typical of nuclei in the onion epidermis. It is squeezed between the central vacuole (V) and the cell wall (CW).
  • The epidermal cells of onions provide a protective layer against viruses and fungi that may harm the sensitive tissues.
  • The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis.
  • The cell membrane in eukaryotes is continuous with what's known as the cytoskeleton. The cytoskeleton, “cyto” for cell, meaning the cell's skeleton, gives the cell membrane its shape.
