Plants & animals both required food for; air & water for the maintenance & breeding of a cell. Each has to be supplied to the cell of the body in a right quantity .
The transport of material in plants is carried out by the vascular tissue.
A)Vascular Tissue :
There are 2 types of vascular tissues found in plants
B) Transportation of water, minerals & food :
C) Traspiration pulls :
D) Ascent of sap :
E) Translocation :
The process of loss of water in the form of vapours through the aerial parts of the plant is called transpiration.
In higher animals, digested food, gases & waste material are carried by blood. Blood flows through a network of tubes, which are called blood vessles & form a system known as circulatory system.
It consist of heart, blood vessels & the blood.
1) RBC (Red Blood Corpuscles) :
2) WBC (White Blood Corpuscles) :
3) Plasma :
4) Platelets :
The process of removing waste from the body is called excretion
Several organs of body is involved in the process of excretion –
Chemical waste like urea are excreted by urinary system & skin.The excretory system in human beings consists of the following organs:
1) Urinary system or Excretory system :
a) Kidneys :
In our body there is a pair of kidneys located in the abdomen, one each on either side of the vertebral column. Each kidney is brick red in colour and bean-shaped.
It weighs about 150 g and is about 12 cm in length, 6 cm in width and 3 cm in thickness
b) Uterers :
The ureters are two thin-walled, urine carrying ducts. A ureter originates from each kidney and is about 30 cm in length. The ureters run downward and open into the urinary bladder
c) Urinary Bladder :
It is a bag-like structure in which urine is stored. Its size and position varies with the amount of urine it contains.
d) Urethra :
The urethra is the duct which finally discharges urine from the body
2) Function of Kidney
