Solution

The correct option is C Idioblast
  • Idioblasts are crystal-containing isolated plant cells. These are secretory in nature. The deposition of inorganic materials like calcium salts forms the crystal. It is involved in the storage of reserve food, pigments, minerals, latex, gum, resin, tannin, etc.
  • Guard cells are two bean-shaped cells that surround stomata.
  • Bulliform cells are so-called because of their peculiar bubble shape. It mainly occurs on the upper surface of the leaves in monocots. Water present in these cells helps to maintain their shape, but losing turgor pressure during stress allows the leaves to roll up.
  • Silica cells are specialized leaf epidermal cells in grasses with almost the whole cell volume filled with solid silica.

So, the correct answer is option 'Idioblast'.
