How does a cell of a unicellular organism differ from a cell of a multicellular organism? a) it performs all functions. b) it is specialized. c) it is large. d) it never replicates.

The answer is it preforms all functions.

There are many different types of biological cells including lots of cells that are specialized to perform specific functions e.g. neurons are nerve cells whose function is to transmit tiny electrical pulses around an animal's nervous system.

Although different types of cells generally have different specialized functions, some types of processes are common to all, or at least most, cells.

The correct answer will be option-B

Explanation:

The organism can be categorized into two types on the basis of a number of cells: Unicellular organism composed of a single cell and a multi-cellular organism composed of many cells.

The unicellular organism differs from the multi-cellular organism in a structural and functional way that a unicellular cell is specialized to perform all the functions and shows structural adaptations to survive.

The multicellular organism posses the functional role but structurally they are different from the unicellular cell.

Thus, Option-B is the correct answer.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
