Question

why multi cellular organism required complex way of reproduction​

Answer 1

Hey there,

Please find your answer below, hope it helps.

Answer:

In a unicellular organism, the cellular arrangement is too primitive and hence they use simple ways of reproduction such as fission and fragmentation to produce new copies of themselves. Whereas, in multicellular organisms, it would be too impractical for it to just use simple modes of reproduction and split into new copies since cells are organised into tissues, specialised tissues are organised into organs and these organs are placed in definite places in the body. Hence, in such a carefully organised situation, it is to be understood that multicellular organisms need complex ways to reproduce.

This is kinda long, but if you understand the concept behind this answer, you could definitely frame it in your own words.

Thanks and have a great day! ;)

Answer 2

Explanation:

multicellular organisms cannot reproduce by cell because they are not simple random collection of cells. therefore they require to usemore complex way of reproduction
