Introduction
Overview
Hello everyone, my name is Ragini Singh, and today I’ll be presenting on a topic that is literally the foundation of life as
we know it — Carbon.
But before we dive into the details, let’s take a moment to understand why this topic is so important.
Why talk about carbon? Why does it matter?
From the simplest single-celled organisms to the largest animals on Earth, they all have one thing in common: they are
carbon-based.
So the real question becomes — why did biology choose carbon as its first building block?
02
What is Carbon?
Definition
Chemical Element
Unique Properties
Building Blocks
Carbon is a chemical element with
the symbol C and atomic number 6.
It’s a non-metal, and what makes it
really special is its ability to form four
bonds with other atoms.
In simple words, carbon is like the
LEGO block of life — it can connect
in many ways and build endless
structures.
03
Why is Carbon Important?
Significance
Carbon is everywhere. It’s in the food we eat, the air we breathe, and in our bodies.
Proteins, fats, carbohydrates — all the major molecules that make up our body — are carbon-based.
DNA, which stores our genetic code, also has carbon at its core.
Without carbon, life wouldn’t exist.
04
Carbon’s Special Properties
Unique Attributes
Forms 4 covalent bonds
Bonds easily with hydrogen, oxygen, nitrogen, and other carbon atoms
Can make long chains, rings, and branches
Forms stable and complex molecules
These unique properties make carbon perfect for building the complex structures required for life.
05
Carbon in Living Organisms
Role in Life
1
Organic Compounds
Almost all living organisms — plants, animals, bacteria — are made
of organic compounds based on carbon.
2
Photosynthesis
In plants, carbon is captured from the air through photosynthesis.
3
Carbon in Cells
In humans and animals, every cell contains carbon-based molecules
— from our skin to our brain.
