Transport of materials necessary in a plant or in an animal because due to which it transport food and oxygen and other use full component to other part of body and also help to remove waste from body that are require for survive.
Platelets of blood are responsible for the clotting of the blood If there are no platelets, then blood will not clot as result when we get injury blood starts flowing from body.
The tiny opening pores present on the leaf surface are known as stomata which is surrounded by two kidney like structure called guard cells.
Functions of stomata are
Transpiration serves the following functions in plants
There are four components of blood:
i)Red blood cells
ii) white blood cells
iii)platelets
iv) plasma.
Blood needed by all the parts of a body because it transport food and oxygen to the cell of body and help to expel out carbon dioxide and waste from our body. Blood also fights becteria and diseases and carries hormones around the body.
The red pigment present in blood called Haemoglobin which makes blood red.
The heart is an organ which beats continuously to act as a pump for the transport of blood. This blood sends oxygen and nutrients to all parts of your body and carries away carbon dioxide and waste products it has four chambers helps to avoid mixing up of blood-rich in oxygen with the blood-rich in carbon dioxide.
Certain waste products are produce during the functioning of body cells. which are toxic for our body and need to remove because it cause certain problem for our body .
