(a)
Advantages of sexual reproduction over asexual reproduction are as follows:-
1. In sexual reproduction, more variations are produced. Thus, it ensures the survival of species in a population.
2. The newly formed individual has characteristics of both the parents.
3. Variations are more viable in sexual mode than in asexual one. This is because, in asexual reproduction, DNA has to function inside the inherited cellular apparatus.
(b)
Planaria reproduce by regeneration
Plasmodium reproduces by multiple fission.
(c)
(1) It is a simpler and faster mode of reproduction.
(2) Spores being small and light, get easily dispersed through wind, water and animals.Thus, the spread of organism becomes easier.
(3) Spores bear thick resistant covering to enable then to survive in unfavourable conditions.
