Solution
The correct option is A Idioblast
Nitrogen is the main constituent of amino acids which polymerse to form proteins. Pepsin and invertase are enzymes. Enzymes are protein molecules and contain nitrogen as the main constituent. Bacteriochlorophylls contain pyrrole rings. Pyrrole is nitrogen-containing heterocyclic compounds. An idioblast is an isolated plant cell, that differs from neighboring tissues. They have various functions, such as storage of reserves, excretory materials, pigments, and minerals. The ergastic substances or secondary metabolites of idioblasts usually lack nitrogen.
