Classification Of Animal On The Basis Of Body Shape/Symmetry

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.
