    Saksham Acharya 2 years, 4 months ago

    Nephrone is the most important diagram in this chapter. CBSE also ask either the diagram of nephrone Or neurone. Although it is just an observation of past few years question paper. My honest suggestion is that U should practice the diagram of alimentary canal, villi, and human heart as well because a simple question i.e to explain their structure and function is usually asked

    Saksham Acharya 2 years, 4 months ago

    Reproduction is not necessary for the survival of an organism that's why it is also not a life process but it is important for the continuation of a species, without reproduction it is impossible for an species to exist for long period. Hence the conclusion is reproduction is essential / necessary .
