In hydroponics which part of the plants is immersed and it is grown in a ____ solution
1 Whole plant, defined nutrient
2 Vegetative parts, dilute
3 Roots, defined nutrient
4 Roots, undefined solution
Explanation:
In hydroponics root of the plant is immersed in defined nutrient solution. A plant roots are continuously bathed in aerated nutrient solution.

Assertion : Plants lack excretory organs Reason : Plants usually absorb nutrients and lead a passive life
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Plants absorb nutrients from soil hence they lack excretory organs. As they lack mouth particulate matter in not taken.

Which of the statement from the following is correct :
1 Hydroponics has been successfully employed for the commercial production of vegetables such as tomato, seedless cucumber and lettuce
2 In hydroponics, the nutrient solution must be adequately aerated to obtain optimum growth.
3 Some plants growing near nuclear test sites take up radioactive strontium.
4 All of them
Explanation:
All of them are correct. Hydroponics has been successfully employed as a technique for the commercial production of vegetables such as tomato, seedless cucumber and lettuce. It must be emphasised that the nutrient solutions must be adequately aerated to obtain the optimum growth. some plants growing near nuclear test sites take up radioactive strontium.

Growing plant in nutrient solution in complete absence of soil was first demonstrated by
1 Julius Van Neil
2 Julius Von Sachs
3 Arnon
4 Hugo von Mohl
Explanation:
In 1860, Julius von Sachs, a prominent German botanist, demonstrated, for the first time, that plants could be grown to maturity in a defined nutrient solution in complete absence of soil. This technique of growing plants in a nutrient solution is known as hydroponics.
