Answer 1

Answer:

The organisms with single-celled body organisation are referred to as unicellular organisms. Being single-celled, cell division in these organisms gives rise to offspring (mainly asexual reproduction) and therefore, there is no need of special organ system for the process of reproduction. For example, binary fission in Amoeba takes place by enlargement of the cell and increasing cell content followed by division of mother cell into two daughter cells, each of which is now offspring Amoeba. Other methods of reproduction in unicellular organisms include fragmentation, fission, budding etc. Multicellular organisms consist of multiple cells which are organised into tissues, organs and organ systems. Owing to the complexity of their body organisation, they have specialised reproductive system and reproduce by sexual reproduction.

$\Large\textsf\textcolor{red}{Modes of Sexual reproduction :- }$

➛ Two important stages of Sexual Reproduction are :-

↦ Gametogenesis :- It is a process of formation of gametes . Male gametes are called as Sperms in animals and Pollen Grains in plants . Female gametes are called as Ova in animals and Ovules in plants.

↦ Fertilization :- It is the process of fussion of male and female gametes , to form Zygote .
