Which characteristic distinguishes living organism unexceptionally from the non-living?

  1. Metabolism

  2. Reproduction

  3. Movement

  4. Interaction with the environment

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  1. Metabolism occurs 'unexceptionally in all living organisms' and this is a defining feature of living beings. 
  2. Reproduction is absent in sterile or infertile living beings.
  3. Organisms like the majority of sponges and plants do not move, but they're still living.
  4. Patients in a coma do not interact with the environment, yet all the metabolic processes occur thus they are living.
So, the correct option is "Metabolism",

E Correct answer
Explanation

Living things are lively and active and exhibit characteristics of life, like growth, movement, reproduction, response to stimuli (like touch, smell, light) . These activities are done by the cells of which the living things are made up of. Some examples of living things around us are human beings, animals, plants and microorganisms.

So, the correct answer is 'All of the above'.

  1. accretion

  2. accumulation

  3. adaptation

  4. organisation

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Non-living things increase in size due to the addition of similar materials to their outer surface, they include crystals, glaciers, stones and mountains

So, the correct answer is 'accretion'

Living organisms must maintain a constant internal environment.

  1. True

  2. False

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Living organisms must maintain a constant internal environment while living in a constantly changing external environment. Maintaining the internal environment is important because the processes that keep the cell alive can only take place under certain conditions. There are different processes that occur in the body to maintain the constant internal environment such as diffusion, osmosis, homeostasis, active transport, passive transport, endocytosis, exocytosis, etc. Homeostasis helps to maintain an equilibrium of an internal environment. 

So, the correct answer is 'True'

Characteristics of living things are

  1. Made up of cells

  2. Growth

  3. Response

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All living things and dead are made up of the cells which perform life processes for maintaining life. They give the response to the stimulus or environmental factors. But growth is the characteristic of both living and dead as dead like wood shows growth by the absorption of water. Thus, the growth is the characteristics of living things but not the defining or fundamental properties of living things. Hence, the correct answer is option D.

In nonliving things

  1. Growth occurs from inside

  2. Growth occurs from outside

  3. Reproduction is asexual

  4. Cell is the structural unit

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Non-living things do not grow through internal metabolic functions but by adding on from the outside. Non-living things do not need the energy to continue to exist. Some nonliving things such as crystals grow by accumulating more of the same material of which they are made.
  • Living things exhibit growth, movement, reproduction, respiration and metabolism. Living things use energy, respond to stimuli and adapt to their environment.
  • So, the correct answer is 'Growth occurs from outside'.
