Weekly Quiz Competition

Question 1
1 / -0

Function of zinc is to help in:

A
Synthesis of chlorophyll

B
Bisosynthesis of 3-IAA

C
Closing of stomata

D
Oxidation of carbohydrate

Solution

Zinc is a micronutrient. Zinc is taken by roots from the soil in form of ions. It helps in production of growth hormone, intended elongation and enzymes.
Zinc deficiency causes stunted growth, chlorosis (Interval) Distorted leaves.

(A) Synthesis of chlorophyll
Question 2
1 / -0

Sulphur helps in:

A
Carbohydrate formation

B
Fat formation

C
Protein formation

D
Leaf formation
Question 3
1 / -0

Which one of the following elements helps in photolysis of water and to maintain anion-cation balance of cells?

A
Boron

B
Chlorine

C
Manganese

D
Potassium
Question 4
1 / -0

How many statement are true for boron ?

A
It required for cell elongation, cell differentiation

B
It required for carbohydrate translocation

C
It required for membrane functioning

D
It is a component of several enzymes, including nitrogenase and nitrate reductase both of what participate in nitrogen metabolism.

E
Along with $$Na^+$$ and $$K^+$$, it helps in determining the solute concentration and the anion-cation balm in cells
Question 5
1 / -0

Which of the following micronutrients deficiencies will have immediate effect in Nitrogen assimilation ?

A
Molybdenum

B
Boron

C
Copper

D
Zinc

Solution

Molybdenum is essential to plant growth as a component of the enzymes nitrate reductase and nitrogenase as both are key enyme for nitrogen assimilation, if deficiencies occure will have immediate effect in nitrogen assimilation.
So, the correct answer is 'Molybdenum'
Question 6
1 / -0

Nitrogen deficiency causes:

A
Chlorosis of young leaves

B
Chlorosis of mature leaves

C
Both A and B

D
None of these

Solution

Nitrogen : This is the mineral element required by plants in the greatest amount. It is absorbed mainly as $$NO_3^-$$ through same are also taken as $$No_2^- + NH_4^+$$. Nitrogen is one of the major constituents of proteins, nucleic, acids, vitamins, and hormones.

The deficiency of nitrogen can cause chlorosis in both young and mature leaves. Chlorosis is the less of cheorophyle leading to
So, (C) option is correct.
Question 7
1 / -0

Soyabean root exports fixed nitrogen as ________ by __________.(respectively)

A
Ureides; Phloem

B
Ureides; Xylem

C
Amides; Phloem

D
Amino acids; Xylem

Solution

Soyabean plant can access atmospheric nitrogen through a symbiotic relationship with nitrogen‐fixing bacteroids that reside in root nodules. In soybean, the products of fixation are the ureides allantoin and allantoic acid, which are also the dominant long‐distance transport forms of nitrogen from nodules to the shoot. And it transported by xylum. From roots to shoots.
Question 8
1 / -0

Identify true statements regarding IRON:-

(i) It is present in two amino acids - cysteine and methionine.
(ii) It is the main constituent of several coenzymes, vitamins.
(iii) It is required in a larger amount in comparison to other micronutrients.
(iv) It is an important constituent of proteins involved in the transfer of electrons.
(v) It is essential for the formation of chlorophyll.
(vi) It activates the catalase enzyme.

A
(i),(ii),(iii) and (v)

B
(iii),(iv),(v) and (vi)

C
(i),(ii),(iii) and (iv)

D
(i),(iii),(iv),(v) and (vi)

Solution

i. Cysteine and Methionine are sulfur-containing amino acids.
ii. It is the main constituent of co-factor and minerals. co-factors are metal ions such as iron, zinc, cobalt, and copper that loosely bind to an enzyme’s active site.
Remaining are true statements.
So, option B is the correct answer.
Question 9
1 / -0

Cu has mainly utilized in:

A
Balancing function

B
Catalytic function

C
Toxic effect

D
All of the above

Solution

Cu has mainly utilized in : B. Catalytic activity.

$$Cu$$ plays an important role in our metabolism. It allows many critical enzymes to function property. copper maintain the strength of the blood vessels, skin, connective tissue throughout the body.
Question 10
1 / -0

Which chemical is produced from a jet engine?

A
Bromine Oxide

B
Nitrogen Oxide

C
Nitric Oxide

D
Carbon dioxide
