Question

Consider the following characteristics:

i) Highly organized

ii) Display homeostasis

iii) Reproduce 

iv) Take energy from the environment and transform it

Which of the character(s) is/are common to a cell and a vacuum cleaner?


  1. None of the above

  2. All of the above

  3. i and iv only

  4. i only


Solution

The correct option is C

i and iv only


Both cell and a vacuum cleaner have organized machinery and both of them take energy from the environment to transform it. A vacuum cleaner takes in electrical energy and transforms it into mechanical energy, whereas, a cell takes in light energy from sunlight or chemical energy from complex food and transforms it into various forms.

However, a vacuum cleaner does not display homeostasis and cannot reproduce on their own.
