Weekly Quiz Competition

Question 1
4 / -1

Which one of the following elements in plants is not remobilised?

A
Phosphorus

B
Potassium

C
Sulphur

D
Calcium

Solution

Calcium is not remonilized from the leaves to the fruits, like potassium, phosphorus and sulphur. It occurs abundantly in a non-exchangeable form such as anorthite (CaAl₂Si₂O₈).
Question 2
4 / -1

That element which helps in electron transport in the process of photosynthesis

A
Zinc

B
Chlorine

C
Manganese

D
Boron

Solution

During noncyclic electron flow the electron hole in P-680 is filled by electrons obtained by photolysis of water. As a result, there is an evolution of oxygen and the electron move through Mn-protein bound to PS II. In this transport Mn++ is oxidised to Mn+++ and then reduced to Mn++in a cyclic manner. The manganese thus transfers electrons from water to photosystem II and thus plays an important role in electron transport in the process of photosynthesis.
So, the correct answer is option B.
Question 3
4 / -1

In cabbages, ‘Whiptail’ is a characteristic deficiency disease. It is caused by the deficiency of

A
Chlorine

B
Molybdenum

C
Magnesium

Solution

Whiptail disorder is caused due to deficiency of molybdenum in cauliflower.
In young plants the deficiency symptoms are chlorosis of leaf margins and the whole leaves may turn white. The leaf blades do not develop properly. When the deficiency is severe, only the midribs develop. This condition is commonly known as 'Whiptail'.
Question 4

Lime is added to the soil which is too

A
Alkaline

B
Acidic

C
Salty

D
Sandy

Solution

Liming Acidic Soil – Adding Lime. Your soil is acidic and you would like to change the pH so that it is less acidic. The universal advice is to add lime to the soil ie liming your soil. Lime is alkaline and it will neutralize the acidity of the soil and make it more neutral.
