What Makes Something Alive?

B2

Life is a fascinating concept that scientists have studied for a very long time.

Have you ever wondered what separates living things from non-living things?

It's not always an easy question to answer, but there are some key characteristics.

All living organisms, like plants and animals, grow and develop over time.

They also need energy to survive, which they get from food or sunlight.

Living things can reproduce, meaning they can create new individuals of their own kind.

Think about how a cat has kittens or a flower makes seeds.

Another important trait is that living things respond to their environment.

A plant will turn its leaves towards the sun to get more light.

Animals might run away from danger or move towards a source of water.

Living organisms also have a complex organization, made up of cells.

These cells work together to keep the organism functioning.

Furthermore, living things adapt to their surroundings over many generations.

This adaptation helps them survive better in different conditions.

So, life is a dynamic process involving growth, energy use, reproduction, response, organization, and adaptation.
