Answer 2

If a sporangium is derived from a single cell, it is called Leptosporangiate.

Option: A

Explanation:  

• Sporangium is formed from the adult plant in which the ‘number of chromosomes’ are equal to the number of chromosomes in an adult plant.  

• It is different from gametocyte since gamates have haploid number of chromosomes. Sporangium always has diploid number of chromosomes.  

• However the number of cells from which the sporangium is derived can be different in different plants.  

• In case of leptosporangiate the sporangium always develops from a ‘single plant cell’.
