Weekly Quiz Competition

Question 1
1 / -0

Which of the following colours of light gives the maximum absorption peak of chlorophyll?

A
Red

B
Blue

C
Yellow

D
Green

Solution

As the wavelength decreases, the energy increases. It is indirectly proportional. Blue light has maximum energy as compared to the other colours of light.
Question 2
1 / -0

Which of the following produces the maximum amount of oxygen?

A
Forests

B
Marine photoplankton

C
Land mass

D
Crops

Solution

The plants which survive in water are known as photoplanktons. These plants take oxygen in the dissolved state.
Question 3
1 / -0

Food is transported to different parts of the plant through

A
xylem

B
phloem

C
cortex

D
pith

Solution

Xylem & phloem are called vascular tissues and are present in every part of the plant. This special vessel called phloem, transports minerals from the leaf to different parts of the plant in the form of carbohydrates, sugars and proteins.
Question 4
1 / -0

A sequence of light independent reactions happens to produce sugars in plants. What is this sequence called?

A
Calvin cycle

B
TCA cycle

C
Krebs cycle

D
Biological cycle

Solution

In plants, algae and cyanobacteria, sugars are produced by a subsequent sequence of light-independent reactions called the Calvin cycle.
Question 5
1 / -0

What is the correct elaborated form of NADP?

A
Nicotinal adenine dinucleotide phosphate

B
Nicotinamide adrenaline dinucleotide phosphate

C
Nicotinamide adenine dinucleotide phosphate

D
Nicotine adrenal dinucleotide phosphate

Solution

NADP stands for nicotinamide adenine dinucleotide phosphate. It is produced by light-dependent reactions in photosynthesis.
Question 6
1 / -0

Which of the following organelles are involved in photo respiration?

A
Mitochondria and glyoxysomes

B
Mitochondria, nucleus and ribosomes

C
Mitochondria, chloroplasts and peroxysomes

D
Mitochondria, chloroplasts and ribosomes

Solution

Mitochondria is called the power house of cell. As photosynthesis takes place in chloroplasts, it needs proteins for initiating the reaction. So, photo respiration takes the aid of mitochondria, chloroplasts and peroxysomes.
Question 7
1 / -0

Which of the following products is common in respiration and photosynthesis?

A
ATP

B
Quinon

C
Chlorophyll

D
Cytochrome

Solution

.
Question 8
1 / -0

What is the first food substance that plants make in photosynthesis?

A
Sugar

B
Starch

C
Fats

D
Proteins

Solution

Sugar is a simple form of carbohydrates as compared to starch, fats and proteins. It uses sugar as the first food substance.
Question 9
1 / -0

Certain photosynthetic bacteria consume carbon dioxide, but never release any oxygen. Such kind of photosynthesis is known as

A
anerobic photosynthesis

B
oxygenic photosynthesis

C
carbonic photosynthesis

D
anoxygenic photosynthesis

Solution

There are some types of bacteria that carry out anoxygenic photosynthesis which consumes carbon dioxide, but does not release oxygen.
Question 10
1 / -0

In photosynthesis, the process of conversion of carbon dioxide into sugars is called

A
carbon degradation

B
carbonic release

C
carbon emulsification

D
carbon fixation

Solution

Carbon dioxide is converted into sugars in a process called carbon fixation. This process occurs during the Calvin cycle.
Question 11
1 / -0

Which part of photosynthetic bacteria contains the proteins that are required to gather light for photosynthesis?

A
Nucleus

B
Nucleolus

C
Cell membrane

D
Peptidoglycan layer

Solution

In photosynthetic bacteria, the proteins that gather light for photosynthesis are embedded within cell membranes.
Question 12
1 / -0

Which factor is responsible for giving the respective colours to various photosynthetic organisms?

A
Non-absorbed part of the light spectrum

B
Absorbed part of the light spectrum

C
Accessory pigments

D
Chemical components

Solution

The non-absorbed part of the light spectrum gives photosynthetic organisms their colour.
Question 13
1 / -0

Which of the following factors shows negligible effect on the light phase of photosynthesis?

A
Light

B
Temperature

C
Water

D
Chlorophyll

Solution

Temperature has very less effect or no effect on the process of photosynthesis. Whereas light, water and chlorophyll have more effect on photosynthesis.
Question 14
1 / -0

KOH is often used in photosynthetic experiment because

A
it gives out CO₂ for dark reaction

B
it splits to provide hydrogen ions

C
it quickly absorbs CO₂

D
it releases oxygen

Solution

.
Question 15
1 / -0

Which component acts as the major reducing agent in chloroplasts?

A
NADPH

B
NADP

C
ATP

D
RuBP

Solution

NADPH is the main reducing agent in chloroplasts.
