Question

How are modes of reproduction different in unicellular and multicellular organisms 0th?​

Answer 1

$\huge\red{Unicellular}$

Unicellular organisms generally divide by asexual reproduction which involves budding, binary fission, multiple fission, fragmentation, spore formation.

$\huge\red{Multicellular}$

Multicellular organisms can divide by sexual as well as asexual methods. For example, vegetative propagation in all plants is a means of asexual reproduction while all higher animals reproduce sexually.

Answer 2

Modes of reproduction in Unicellular organism

• In unicellular organism , the mode of reproduction is simple.

• Unicellular organisms have a simple cellular structure.

• They reproduce by simple methods of reproduction like binary fission, multiple fission, budding etc.

Modes of reproduction in Multi - cellular organism

• A multi-cellular organism have a complex cellular structure, have specialised functions.

• it reproducing by simple methods does not work.

• So for reproduction, they develop reproductive organs like flowers in plants, Ovaries and testis in an animal.

• These organs produce gametes. Gametes on fertilisation and growth result into new individual organisms.
