Question:
Which one of the following statement is not true?
Tapetum helps in the dehiscence of anther.
Exine of pollen grains is made up of sporopollenin.
Pollen grains of many species cause severe allergies.
Stored pollen in liquid nitrogen can be used in the crop breeding programmes.
Solution:
The tapetum is a specialized layer of nutritive cells found within the sporangium, particularly within the anther, of flowering plants, where it is located between the sporangenous tissue and the anther wall. Tapetum is important for the nutrition and development of pollen grains, as well as a source of precursors for the pollen coat, however it does not help in dehiscence of the anther. So, the correct answer is 'Tapetum helps in the dehiscence of anther.'
