Weekly Quiz Competition

Question 1
1 / -0

The concentration of macro nutrients in dry matter is

A
less than10mmole kg-1

B
0.1mg

C
10mg

D
excess of 10m mole kg^-1

Solution

Explanation:

Macronutrients are generally present in plant tissues in large amounts (in excess of 10m mole Kg ^–1 of dry matter).
Question 2
1 / -0

Which among the following essential element play important role in opening and closing of stomata?

A
Potassium

B
Phosphorus

C
Sodium

D
Cobalt

Solution

Explanation:

Essential elements can alter the osmotic potential of a cell. Potassium plays an important role in the opening and closing of stomata.
Question 3
1 / -0

Chlorosis is referred as

A
Death of tissue

B
Inhibition of cell division

C
Loss of chlorophyll

D
Premature fall of leaves

Solution

Explanation:

Chlorosis is the loss of chlorophyll leading to yellowing in leaves. This symptom is caused by the deficiency of elements. N, K, Mg, S, Fe, Mn, Zn and Mo.
Question 4
1 / -0

Phosphorous is a constituent of A. Cell membrane B. Nucleic acids C. cellwall D.chlorophyll

A
D and A

B
B and C

C
C and D

D
A and B

Solution

Explanation:

Phosphorus is a constituent of cell membranes, certain proteins, all nucleic acids and nucleotides
Question 5
1 / -0

Which element is essential for photolysis of water?

A
Carbon

B
Oxygen

C
Chlorine

D
Nitrogen

Solution

Explanation:

Chlorine is absorbed in the form of chloride anion (Cl–). Along with it Na+ and K+, it helps in determining the solute concentration and the anioncation balance in cells. It is essential for the water-splitting reaction in photosynthesis.
Question 6
1 / -0

Magnesium is component of

A
Enzyme

B
Haemoglobin

C
Florigen

D
Chlorophyll

Solution

Explanation:

It is absorbed by plants in the form of divalent Mg²⁺. Magnesium is a constituent of the ring structure of chlorophyll and helps to maintain the ribosome structure.
Question 7
1 / -0

The most abundant element found in plants is

A
Iron

B
Manganese

C
Nitrogen

D
Carbon

Solution

Explanation:

Carbon is generally present in plant tissues in large amounts and mainly obtained from CO₂ and H₂O.
Question 8
1 / -0

Element present in middle lamella

A
Zinc (Zn)

B
Copper (Cu)

C
Calcium (Ca)

D
Potassium (K)

Solution

Explanation:

Calcium is required by meristematic and differentiating tissues. During cell division it is used in the synthesis of cell wall, particularly as calcium pectate in the middle lamella.
Question 9
1 / -0

It is the technique of growing plants in above-ground strands provided with fine mist of normal solution.

A
Aeroponics

B
Hygroponics

C
Chemoponics

D
Hydroponics

Solution

Explanation:

Aeroponics is the technique of growing plants in above ground strands provided with fine mist of normal solution. It is used to know the deficiency symptoms of minerals.
Question 10
1 / -0

Hydroponics refers to growing plant in

A
Water

B
Soil culture

C
Solution of mineral nutrients

D
Tissue culture medium

Solution

Explanation:

Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent.
