We classify organisms for several reasons: to make the study of different types of organisms easier, to group all life forms together to study as a whole, and to reveal relationships between organisms. Animals are classified as vertebrates or invertebrates, with vertebrates having backbones and invertebrates lacking them. Vertebrates are further divided into warm-blooded and cold-blooded categories based on their ability to regulate body temperature. Plants are similarly classified as flowering or non-flowering, with flowering plants divided into gymnosperms and angiosperms.

2. We classify animals for the following
reason :
It makes the study of different types
of Organism easy
We can now all life forms together and
as a whole
It reveals the interrelationship among
organisms

3. Animals
Plants
a living organism that feeds on organic
matter, typically having specialized sense
organs and nervous system and able to
respond rapidly to stimuli.
a living organism of the kind exemplified by
trees, shrubs, herbs, grasses, ferns, and mosses,
typically growing in a permanent site,
absorbing water and inorganic substances
through its roots, and synthesizing nutrients
in its leaves by photosynthesis using the
green pigment chlorophyll.

Invertebrates
Animals of this group have
backbone in their body
Animals of this group do not
contain backbone in their
body
Animals are divided in two types

6. Warm blooded
vertebrates
Cold blooded
vertebrates
Those vertebrates which can change their
body temperature according to the
surrounding temperature article cold blooded
vertebrates .
Those vertebrates which can't change their
body temperature according to the
surrounding temperature and cold warm

Non - Flowering
Plants
Plants that bear flowers are
flowering plants
Plants that does not bear
flowers are flowering plants
Plants are divided in two types

11. Flowering plants are divided into 3 types
1. Thallophyta : They are divided in 2
groups (i) Fungi
(ii) Algae
2. Bryophyta : Eg- Moss, Riccia, Marchantia
3. Pteridophyta : Eg- Ferns, Azolla, Marsilea

12. Flowering plants are divided into 2 types
1. Gymnosperm : Eg - Pinus
2. Angiosperm : They are divided in 2 groups
(i) Monocotyledon
(ii) Dicotyledons
