Plants are diverse organisms that can be classified based on various characteristics. 
Based on their structure and growth habits, plants can be categorized into three main 
types:
Climbers
They are the plant that does not have stem 
and if stem is present, it is very weak. 
These plants grow readily on support or 
over other plants. e.g. money plant, 
grapevine, pea, etc.
Cr eepers
These plants also have very weak stems, 
and plants creep along the surface of 
ground and spread on the ground. e.g. 
watermelon, pumpkin and bottle gourd.

On the Basis of Life Span
Classification of plants on the basis of life are given below
Annual Plants
Annual plants complete 
their full life cycle in one 
year, from seed to seed 
production. Examples 
include wheat, corn, and 
sunflowers.
Biennial Plants
Biennial plants take 2 
years to complete their 
life cycle - vegetative 
growth in year 1, 
flowering/fruiting in year 
2. Examples include 
carrots, beets, and 
parsnips.
Perennial Plants
Perennials live for multiple 
years, with spreading 
roots. They bloom 
spring/summer, then shed 
leaves fall/winter. 
Examples: mango, apple 
trees.

On the Basis of Region
Plants are categorised into the following
Hydrophytes
Aquatic plants live in/on water. 
Adaptations: thin cuticle, large flat 
leaves, air sacs for flotation, reduced 
roots, waxy leaf coating. E.g. lotus, 
hydrilla, water lily.
Xerophytes
These plants thrive in dry, desert-like 
conditions. They have adaptations like 
deep roots, small waxy leaves, and 
fewer stomata to conserve water.
Mesophytes
These plants grow in moderate 
environments, not too dry or wet. E.g. 
mango, neem. They can't survive 
flooding, as their roots can't respire.
Halophytes
These plants thrive in salty 
environments like mangrove swamps 
and coastal marshes. They have 
adaptations like aerial roots to survive 
the high salinity.

Significance and Importance of Plants
Earth is called a green planet due to the presence of plants or it plants are considered to 
be the first living organisms born on the Earth. Plants are beneficial in following ways
Gas Balance
Plants help in 
maintaining 
gaseous balance in 
the air through 
photosynthesis. 
They consume CO2 
emitted by animals 
and produce 
oxygen.
Environmental 
Balance
Plants help in 
maintaining 
temperature, soil 
erosion, ecological 
balance, support 
rainfall, maintain 
soil fertility etc 
through various 
mineral and water 
cycles.
Shelter
Plants are the 
shelter for birds and 
few animals like 
monkeys and 
squirrels.
Food Source
Plants produce their 
own food through 
photosynthesis, 
using sunlight, CO2, 
and water. They 
provide essential 
nutrients like 
carbohydrates, 
proteins, and 
vitamins.

Oils
Plants produce various 
edible oils like mustard, 
groundnut, coconut, and 
sunflower oil.
Medicine
Plants provide material 
that have medicinal value. 
Tulsi, neem, garlic, 
aloevera, cinchona, poppy 
etc are some of the plant 
that have medicinal value.
Mat er ials
Plants provide various 
useful materials like wood, 
paper, fiber, and gum for 
human use.
There are some flowers which are consumed. e.g. kachnar in Uttar Pradesh, banana 
flower in Kerala, Sahjan flower in Maharashtra. Different kind of beverages are obtained 
from plant and plant products like tea, coffee and alcoholic drink. Plants provide numerous 
kind of spices, perfumes, dyes, natural colour etc.
