Solution culture technique is used for

  1. finding rate of assimilation of nutrients

  2. finding concentration of each nutrient

  3. finding essentiality of a particular nutrient

  4. micropropagation of plants


Correct Option: C
Explanation:

Solution culture is used for finding essentiality of a particular nutrient by growing plant in an artificially provided nutritive culture which contains all element except one particular nutrient.

Deficiency of which element causes excessive interveinal chlorosis?

  1. Magnesium

  2. Calcium

  3. Chlorine

  4. Phosphorus


Correct Option: A
Explanation:

Which of the following is a total root parasite?

  1. Cuscuta

  2. Rafflesia

  3. Loranthus

  4. Santalum album


Correct Option: B
Explanation:

Rafflesia is a total root parasite. It is completely dependent upon host root for food, water and minerals.

Mistletoe is a
