Secretory substances : Some of the cells syntehsize such substances which are not concern directly with nutrition and growth. They are called as secretory substances & are secreted by the gland cells viz. – Enzymes, Nector etc.

  1. Enzymes – They are the proteins which act as biocatalyst in various metabolic activities. The enzymes break the complex food material into small soluble and simple molecules.
    Examples – amylase, maltase, protease etc.
  2. Nector – It is sweet organic substance which is secreted by the nector glands in flowers. It contains sucrose, glucose & fructose sugar. The insects get attracted by the nector and help in pollination.
