STD – 6th SUB – SCIENCE 2. Classification of living thing

Presented By -Panchal Amol

Points to Study Criteria for classification.Classification of plant.Flowering and non-flowering plants. Plants can be classified according to the differences in the

height of their steams and their branches. 1) Trees 2) Shrubs 3) Climbers and Creepers 4) Herbs

Classification of plants based of their life-cycle . 1) Perennials 2) Biennials 3)Annuals

Classification of animals 1) Wild and domestic animals. 2) Unicellular and

Multicellular animals . 3) Terrestrial , Aquatic , Amphibious animals 4) Vertebrate and Invertebrate animals. 5) Classification based on body covering

2. Classification of living thing

Criteria for classification

1.There are various varieties of plants and animals in our surroundings.

2.The credit of classification of plants goes to Carolus Linnaeus.

3.The similarities ,differences and variety are the criteria of classification.

Classification of plant.

G



1) Based on flowerA) Flowering

plants – Plants that bears flower are called flowering plants. e.g.- Rose, Hibiscus, Mango.

G



1) Based on flowerB) Non-flowering

plants – Plants that do not bears flowers are called non-flowering plants. e.g.- Spirogyra, Ferns, Fungus.

G



2.Based on steams and heighta)Trees -Trees

grows very tall and have hard and strong stem. e.g.- Mango, Coconut .

G



2.Based on steams and heightB) Shrubs –

Shrubs are of medium height 2to3m and with strong stem . e.g.- Lemon , Orange.

G


2.Based on steams and heightC) Herbs –

Plants with flexible and soft stem. E.g.- Grass, Chilli , Gram.


G



2.Based on steams and heightD) Climber

/Creeper – Weak stem and grow on support. e.g.- Cucumber, Bitter gourd .

G



3. Classification based on live-cycle.Perennials

– Plants that live

many year. e.g.-

Mango, Coconut, Neem .

Biennials – Plants that live for 2 years. e.g.- Carrot, Beat, Radish.

Annuals – Plants that live for 1 year. e.g.-

Bajara , Jowar , Sunflower.

3. Classification based on live-cycle.

a)Perennials – Plants that live many year. e.g.- Mango, Coconut, Neem .


G




b)Biennials – Plants that live for 2 years. e.g.- Carrot, Beat, Radish.

G


c) Annuals – Plants that live for 1 year. e.g.- Bajara, Jowar, Sunflower.



G



Classification of animals

1) Based on cell number

a) Unicellular – Amoeba, yeast etc.

b) Multicellular – Man, cow, cat etc.

Unicellular Multicellular

Ex. Yeast, Amoeba , chlorella

Ex. Man , Dog , cat , rose

G



2) Based on habitat a) Terrestrial – Lives on land e.g. – Horse,

cow, dog etc. b) Aquatic – Lives in water e.g. – Fish,

octopus, jellyfish etc. c) Amphibious – Lives on both land and in

water e.g. – Frog, snake, tortoise etc.


G



3) Based on vertebral column

a) Vertebrate – Animal with vertebral column e.g. – Man, cat, dog, cow etc.

b) Invertebrate – Animal do not have vertebral column e.g.- Butterfly, crab etc.


G




4) Classification based on body covering

a) Animal with scale e.g.- Snake, tortoise.

b) Animal with hair e.g.- Monkey, bear

c) Animal with feather e.g.- All birds.

G


5) Based on mode of reproduction

a) Oviparous e.g.- Birds, tortoise.

b) Viviparous e.g.- Man, cow, dog,

cat..


G



6) Wild and domestics

a) Wild e.g.- Tiger, lion, bear.

b) Domestic e.g.- Cow, cat, bull.
