Animal kingdom.....
The animal kingdom divided into two sub kingdoms on the basis of presence or absence of backbone or vertebral column
(A) Invertebrates
Those animals which have no backbone or vertebral column they have following characteristics
Characteristics
grater in numbers than the vertebrates
some invertebrates have hard shell or other type of hard covering called exoskeleton
A few invertebrates have a Skelton inside the body called endoskeleton.
Classification
Phylum protozoa
Phylum Porifera
Phylum Coelenterata
Phylum platyhelminthes
Phylum nematode
Phylum annelida
Phylum mollusca
Phylum arthropoda
Phylum echnodermata
( P,P,C,P,N,A,M,A,E,)
(B) Vertebrates
Animals who Posses backbone or vertebral column
Five major classes of vertebrates
Fishes
Fishes are aquatic animals, they have head trunk and tail, the organs of breathing are gills, they are cold blooded animals, most fishes lay egg in the water.
Amphibian
The animals have tendency of living in water as well as on land, they are cold blooded animals i-e Frogs, Toads and Salamanders
Reptilian
Basically reptiles are creepers and first true land vertebrates , many reptiles live in water , their skin is dry, hard , and rough. They breathe by lungs i-e Dinosaurs, lizards, Crocodiles, and snakes , tortoises are best examples
Birds(Aves)
They belongs to class Aves birds, main characteristics of birds
The birds have feathers on their body
They stand on two lags,
Their limbs are modified into wings
The Aves are divided into two large groups
1- Running birds
2- Flying birds
The birds which cannot flay but run very faster known as running birds, they have weak wings
The birds have tendency flaying known as flaying birds , their wings have feathers to flight and their pictorial muscles are very strong, the feet of such types of birds are webbed
Mammals
These are warm blooded animals, having hair on their body and the female mammals nourish their young on their milk
Types of mammals
1- Egg laying mammals
These mammals lay eggs and feed their babies with milk, considered to be connecting link between reptiles and mammals , Duck Bill, and spiny aunt-eater are the best examples.
2- Pouched mammals
These mammals gives birth to under developed babies, their mother keeps them in a pouch on its belly until they developed properly, the mother feeds them in her milk, i-e Kangaroo, Opossum, and Kaola are the
3- Typical mammals
These are true mammals, whose baby completes its development in the body of mother, after the birth mother feed then her milk,
They are further divided into sub groups
Insect eating mammals (Mole)
Edentate mammals ( Pangolin)
Rodent mammals ( Rat)
Flaying mammals (Bat)
Carnivorous mammals ( Sea lion)
Hoofed mammals ( Rhinoceros)
Trunked mammals (Elephant)
Fish like mammals (whale fish)
Classification of some important animals
Name of mammals Location
Blue whale Found in all oceans
Panda China
Dolphin in seas
Kangaroo Australia
Snow leopard Central Asia
Yak Central Asia
Llama South Africa
Ibex wild mountain goat
Reptiles
Cobra south Asia
Alligator north America
Tortoises water
Rattle snake America
Birds
Ostrich desert of Africa
Penguin Antarctic regions
Kiwi new Zealand
Rhea south Africa
Emu Australia
Fishes
Shark found in all oceans
Trout fresh water fish
Classification of plants
Characteristics
There are about half of million spaces of plants on earth.
The plants are animates which need air, light and water for their survival and growth
The synthesis their food by the means of photosynthesis
Water is very essential for their growth thy absorb ground water by means of roots
Plant kingdom
1- non-Green plants
2- green plants
Non-Green plants
Which do not have steam, root, and leaves, they lack chlorophyll so they cannot synthesize their food through photosynthesis i-e bacteria, fungi, and viruses.
Green plants
Plants which contains chlorophyll and synthesize their food through photosynthesis
They are further divided into two
1- flowering plants or Phanerogams
2- non-flowering plants or Cryptogams
Flowering plants
Those plants which contain seed , they are further divided into two
Gymnosperms
Those flowering plants which contains naked and unprotected seeds
i-e Pine, Fir, Spur, and Cypress etc
Angiosperms
Whose seeds protected by a fruit or seedpod
i-e Grass, Crops, Vegetables, Fruit and Weeds
Non-flowering plants
Plants which do not have seed, or seedless plants
They reproduce by spores
They have long life
They cannot grow to large size they generally have simple structure except Ferns
They have no long fiber
i-e Moses, ferns, Algae
