Question 1
1 / -0

Photophosphorylation results in the formation of

A
ATP

B
NADPH + H$$^+$$

C
$$C_6H_{12}O_6$$

D
Glucose

Solution

Photophosphorylation is the process of phosphate group transfer into ADP to synthesize energy-rich ATP molecule making use of light as external energy. Thus option A is the correct answer.
Question 2
1 / -0

Plants are known as purifiers of air due to process of

A
Respiration

B
Photosynthesis

C
Transpiration

D
Desiccation

Solution

Plants are known as purifiers of air because they absorb carbon dioxide and release oxygen. The balance of carbon dioxide and oxygen in the atmosphere is maintained by respiration and photosynthesis. The excess of carbon dioxide may lead to evils like global warming.
So, the correct answer is option B.
Question 3
1 / -0

First acidic compound formed in $${C_4}$$ cycle is

A
OAA

B
Malic acid

C
Pyuvic acid

D
PGA

Solution

First acidic compound formed in C4 cycle is OAA. pyruvate + Pi + ATP PEP + AMP + PPi
PEP + CO2 oxaloacetate
Question 4
1 / -0

Which branch of botany is concerned with the study of photosynthesis?

A
Ecology

B
Psychology

C
Plant physiology

D
Embryology

Solution

Plant physiology is a subdiscipline of botany concerned with the functioning or physiology of plants. It defines the process of photosynthesis, respiration, plant nutrition, plant hormone function, tropisms, nastic movements, photoperiodism, photomorphogenesis, and so on.
So, the correct answer is option C.
Question 5
1 / -0

The energy rich compound generated during photosynthesis is

A
ADP

B
ATP

C
AMP

D
All of the above

Solution

ATP is the energy currency of a cell which provides energy for several life processes. The ATP synthesized during the light reaction of the photosynthesis is used up to fix carbon dioxide in the dark reaction. The ATP gets converted to ADP and releases inorganic phosphate by breaking the bond which liberates about 7.3 kilocalories per mole = 30.6 kJ/mol. It may get converted into AMP by releasing two phosphates to produce an extra amount of energy. It is an exothermic reaction as it involves the breaking of the bonds.
So, the correct answer is option B.
Question 6
1 / -0

Which of the following is known as kitchen of the plant?

A
Chloroplasts

B
Mitochodria

C
Golgi bodies

D
Endoplasmic reticulum

Solution

The chloroplast is called complete photosynthetic units because both the stages of photosynthesis, light reaction, and dark reaction are carried out within this one unit only. Chloroplasts are also known as the kitchen of the cell as it help plants in making food.
So, the correct answer is option A.
Question 7
1 / -0

Chlorophyll is present

A
On the surface of chloroplast

B
In the stroma of chloroplast

C
In the grana of chloroplast

D
Dispersed throughout the chloroplast

Solution

Chlorophyll is present in the grana of chloroplast. Chlorophyll is a major photosynthetic pigment.
Question 8
1 / -0

Which of the following is the site for the Calvin cycle of photosynthesis?

A
Stroma

B
Thylakoid

C
Vacuole

D
Stomata

E
Lamella

Solution
Question 9
1 / -0

The term photosynthesis was coined by

A
Fiescher.

B
Priestley.

C
Blackman.

D
Barnes.

Solution

Photosynthesis is a process by which organic substances in green plants are converted into organic substances. Barner coined the term photosynthesis in the year 1898. It mainly takes place in two steps light and dark reactions. The light reaction produces energy which is utilized during dark reaction for fixation of carbon dioxide.
So, the correct answer is option D.
Question 10
1 / -0

The site for Calvin cycle is the

A
Stroma. .

B
Cytoplasm.

C
Thylakoid membrane.

D
Mitochondrial matrix.

E
Mitochondrial membrane.

Solution

Cytoplasm is the site for glycolysis of cellular respiration. Mitochondrial matrix and mitochondrial membrane are sites for Kreb cycle and electron transport chain of aerobic respiration respectively. Calvin cycle takes place in chloroplast stroma while thylakoid membrane serves as a site for light reaction.
So, the correct answer is option A.
