Explanation:

• A resting spore can be defined as the spore developed by the fungi that facilitates its survival in the unfavorable condition.
• The resting spore protects the spore against the microbial attack and the attack of the environment like sunlight, heat and wind.
• The resting spore remains dormant in the soil and they germinate under suitable condition of water and temperature.
• The resting spore develops in Anabaena.
• A heterocyst is the cynobacterial cell that is completely differentiated.
• This carries out the process of nitrogen fixation.
• The mature heterocyst is responsible for conducting the photosystem  I, this causes the production of oxygen, photophosphorylation and generation of ATP. This process requires the oxygen-sensitive nitrogenase enzyme.
