Why You Think Plants Are Green?


From small plants to large trees of deep forests, from grasslands to seaweeds at the bottom of the ocean, all are green in colour, which gives an amazing and freshening effect to nature and to the mother planet.

The simplest and most excellent answer to this question is chlorophyll.

Yes, chlorophyll is the only pigment, which gives green colour to the plants and keeps our mother planet green.


Chlorophyll is a green coloured, natural and the primary pigment, present in all green plants and in other photosynthetic organisms such as cyanobacteria. The colour of plant leaves and the tender part of stems are green due to the presence of this chlorophyll pigment. There are different types of chlorophyll pigments and are distinguished mainly based on their composition, functions and other characteristics.

Chlorophyll is the most significant and abundant pigment in plants, which plays an essential role in the biological process of photosynthesis by converting light energy into chemical energy. These pigments are present in the plant cell organelles called chloroplasts.


Chloroplasts are the cell organelle found in all autotrophs. These cell organelles are called the site for photosynthesis to occur. In-plant cells, chloroplasts are enclosed in the double membrane fluid called the stroma.

Frequently Asked Questions on Why are plants green

Why are leaves green in colour?

Leaves are green in colour because of the presence of green colour pigments within the plant cell called chlorophyll.

What is Photosynthesis?

Photosynthesis is a biological process of converting light energy into chemical energy in the presence of solar energy, water and carbon dioxide.

How many types of chlorophyll pigments are there?

There are five different types of chlorophyll pigments and are distinguished mainly based on their structure, functions and other features.

What are the main photosynthetic pigments?

Altogether there are five different types of chlorophyll pigments. Among these five types, chlorophyll a and b are considered the primary photosynthetic pigments.

What is the difference between chlorophyll and chloroplasts?

Chlorophyll is the biological pigment, which is green in colour and is found in all plants and other photosynthetic organisms.

Chloroplasts are the cell organelles, which are present only in the plant cell and play an important role in the process of photosynthesis.
