Classification Of Animal On The Basis Of Body Shape/Symmetry.
1) Asymmetrical Animals :-
Those Animals Whose Body Can Not Be Divided Into Equal
Parts Are Called Asymmetrical Animals.
In Other words They Have Irregular Body Shape.
2) Bilateral:-
The Body Of These Animals Can Be Divided Into Equal Parts
In One Plane Of Cutting Only
3) Radial Symmetrical:-
The Body Of These Animals Can Be Divided Into Equal Parts In More Than One Plane Of Cutting.

Mychorrhizae
Short Note On Mycorrhizae :-
.Some Fungi Make Association With The Roots Of Higher Plants Called Mycorrhizae.
.It Is Also a Mutualism In Which Both The Partners get Benefit
.The Hyphae Of Fungi Increase The Soil Contact And Help I The Absorption Of Important
The Substances Like Zinc, Copper , Phosphorous and Other Nutrients.
.The Plant Get All These Substances and As a Result Of Which The Plant Supplies Organic
Compounds To The Fungus.
.In This Way The Fungi And Higher Plants Live Together
.There Are Two Type Of Mycorrhizae:-
1) Endomycorrhizae
2) Ectomycorrhizae
Endomycorrhizae:-
.When The Hyphae Of Fungi Penetrate Into The Inner Side Of Root Cells, These Are Called
Ectomycorrhizae.
Ectomycorrhizae:-
.When The Fungal Hyphae Surround The Roots And Remain Between The Cell But Do Not
Penetrate into The Cells, These Are Called Ectomycorrhizae.

Importance of Fungi
Importance of Fungi:-
Fungi In Food Industry:-
Yeast Is Used In Baking And Wine Making Industry.
Yeast Has The Ability To Ferment Carbohydrate , Breaking
Down Glucose To produce Ethanol and Carbon dioxide .

Fungi In Pharmaceutical Industry :-
Penicillin The First Discovered Antibiotic Is Obtained From
Pencillium Chrysigenum.
The Antibiotic Griseofulvin Is Effectively
Used Against Fungal Infections Of Hair, Nails, Skin, And Ringworm.
Edible Fungi:-
The Mushroom Is Considered Popular Food Throughout The World.
Mushroom Are Famous For Their Taste.
Some Ectomycorrhizae Are Edible.
The Yeast Contain High Level Of Vitamin B and Protein
Fungi Used In Research Projects :-
Yeast Are Mostly Used In Biological Research Projects Due To Their
Rapidly Increasing Generation Time And Increasing Genetic Pool .
Yeast Contain 6000 Genes.

Haemocoel and Coelom
Haemocoel and Coelom :-
Coelom Is The Space Between Body Wall And Alimentary Canal
Formed By Splitting Of Embryonic Mesoderm
Coelome Filled With Heamolymph Is Called Heamocoel.
In Heamocoel The Original Coelme IS Obliterated Dilation Of Blood Vessels.

ECG (Electrocardiogram)
Electrocardiogram :-
The Electrocardiogram Is a Medical Device Used For Recording The Electrical
Activity Of The Heart.
An Electrocardiogram (ECG) Is Used To Measure The Rate and Regularity Of
Heart Beats, As Well As The Size Position Of The Chambers, Thee Presence Of
Any Demage To The Heart and The Effects Of Drugs Or Devices Used To Regulate
The Heart Such As Pacemaker.

Pacemaker
PACEMAKER :-
.It Is Also Called Sinoatrial Node or SA node.
.The SA node Is Composed Of Special Muscle Called Purkinji.
.Pacemaker Is a Specialized Region Of Cardiac Muscles That Maintain
The Rhythm Of The Heart.
.SA node initiates The Electrical Impulse For Heart Beat.
.The Cell Of The SA node Generate Electrical Impulses Which Is Responsible The The
For The Rest Of Heart Electrical Activity.
.The Pacemaker Is Situated In The Walls Of Right Auricle.

Different Between Heamolymph and Blood
Heamolymph and
Blood :-
Heamolymph Is The Circulatory Fluid In Insects. It Does Not Contain Heamoglobin And RBCs And Does Not Transport Oxygen.
Heamolymph Transport Food Only.
While
Blood Contain Different Types Of Cell And Present In Liquid Part
Called Plasma.
As Heamoglobin Is Present Blood Transport Oxygen And Corbondioxide Besides Other Substances.
Animal Like Protists
. Animal Like Protists
.The Protists (Algae) Play A Major role in ecosystem . These Forms The Foundation
Of Food
.It is Estimated That One-Quarter Of World’s Photosynthesis Is Performed By Algea.
.It Play role in nutrients Recycling
.Protists Are Responsible For Decomposing The Organic Matter and recycling The
Nutrients
.Euglena Is Used To Treat Sewage Because Of Its ability To Switch From An Autotrophic
To a Heterotrophic Mode Of Nutrition
.Protists Form Symbiotic Relationship For i,e Trichonympha Lives In The Gut OF Termites
And Produce An enzyme Cellulose Which Digest The Wood
.The Animal Like Protists Causes Diseases In Humans :- I,e Malaria, Amoebic Dysentery , African Sleeping Sickness And Giardiasis .
.Some Protists Have Medicinal And Industrial Uses.
.Chemicals Are Obtained From Ptotists Are Used In The Treatment Of Ulcers , Hypertension And Arthritis.
.Some Species Are Used As Source Of Food
.Red Algae Are Rich In Vitamins And Minerals .
