Answer 2

Explanation:

The question is asking about the correct statement according to unicellular organisms or the organism that is made up of one cell.

So, let's see the options:

(a) In unicellular organisms, tissues work in co-ordination to perform different functions.

• The word itself means that they are made up of one cell. So they don't have tissue which are made up of numerous cells working together. Hence, this is incorrect.

(b) Unicellular organisms do not require food.

• The unicellular organism are also living organism and they need fuel for their body to work. This fuel and energy can be obtained by consumption of food. Hence, this is incorrect.

(c) Unicellular organisms respire and reproduce.

• Yes, they also show basic life processes for the working of their body. They respire to oxidise their food and reproduce to produce more their species. Hence, this is correct✓.

(d) All unicellular organisms move by Cillia.

• The organisms may use other locomotory organs like Pseudopodia, Flagella etc for their movement. Like Amoeba being a unicellular organism use Pseudopodia not Cillia. So this is incorrect.

So, the correct option is:

$\large{ \boxed{ \bf{ \purple{Option \: C}}}}$

And we are done !!
