Which one is the correct equation for photosynthesis?

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

6CO2 + 6H2O + light energy -> C6H12O6 + 6H2O

6CO2 + 6H2O + light energy -> C6H12O6 + 6CO2

6CO2 + 6H2O -> C6H12O6 + 6O2

In visible lights, ____ colour has the longest wavelength while ____ colour has the shortest wavelength.

Yellow, Violet

Red, Violet

Red, Blue

Violet, Red

Which statement is true about the relationship between wavelength and energy of photon.

The relationship between wavelength and energy of a photon is directly proportional.

The relationship between wavelength and energy of a photon is inversely proportional.

What are the products of light dependent reaction in photosynthesis?

ATP, NADPH, and oxygen

Starch, oxygen, and ATP

Chlorophyll, sunlight, and water

Glucose, water, and carbon dioxide

The electron transport chain in non-cyclic photophosphorylation involve

Plastoquinone(Pq) and Plastocyanin(Pc)

Plastoquinone(Pq) and Ferredoxin(Fd)

Plastoquinone(Pq), cytochrome complex and Plastocyanin(Pc)

Ferredoxin(Fd) and Plastocyanin(Pc)

What is the difference between non-cyclic and cyclic photophosphorylation?

Non-cyclic photophosphorylation does not involve electron transport chain, while cyclic photophosphorylation does.

Non-cyclic photophosphorylation produces only ATP, while cyclic photophosphorylation produces both ATP and NADPH.

Non-cyclic photophosphorylation involves only Photosystem I, while cyclic photophosphorylation involves both Photosystem I and Photosystem II.

Non-cyclic photophosphorylation involves both Photosystem I and Photosystem II, while cyclic photophosphorylation only involves Photosystem I. Non-cyclic produces both ATP and NADPH, while cyclic produces only ATP.

What are requires in light independent reaction (Calvin Cycle)?

Carbon dioxide, ATP, and NADPH

Nitrogen, GTP, and NADP+

Glucose, Water, and Sunlight

Oxygen, ADP, and FADH2

90%

75%

25%

16.

What is the difference between PEP carboxylase and Rubisco?

PEP carboxylase has a lower affinity for CO2 and undergoes photorespiration

Rubisco has a higher affinity for CO2 and does not undergo photorespiration

PEP carboxylase and Rubisco have the same affinity for CO2 and photorespiration

PEP carboxylase has a higher affinity for CO2 and does not undergo photorespiration, while Rubisco has a lower affinity for CO2 and can undergo photorespiration.

Xylem cells and phloem cells

Root hairs and stem cells

Guard cells and trichomes

Mesophyll cells and bundle sheath cells

18.

What is the difference bwtween C3 and C4 plants?

C3 plants use the Calvin cycle, while C4 plants use the Hatch-Slack pathway.

C3 plants use the Krebs cycle, while C4 plants use the Calvin cycle.

C3 plants are more efficient in hot climates compared to C4 plants.

C3 plants have a higher water requirement than C4 plants.

19.

Which statement is true about CAM plants?

CAM plants open their stomata during the day to conserve water

CAM plants open their stomata at night to reduce water loss and fix carbon dioxide.

CAM plants fix nitrogen instead of carbon dioxide

CAM plants are not adapted to hot and dry environments

20.

What is the difference between C4 and CAM plants?

C4 plants open their stomata at night to reduce water loss during the day, while CAM plants have a specialized leaf anatomy to minimize photorespiration.

C4 plants have a specialized leaf anatomy to minimize photorespiration, while CAM plants open their stomata at night to reduce water loss during the day.

C4 plants and CAM plants both use the same mechanism for photosynthesis.

C4 plants close their stomata during the day to conserve water, while CAM plants open their stomata all the time.
