Solution

Oxygen is not required for carrying out the process of photosynthesis.
Question 2
1 / -0

Plants have a high nitrogen requirement to synthesise proteins. This is made possible with the help of bacterium Rhizobium. Which of the following statements is incorrect for Rhizobium?

A
It converts atmospheric nitrogen into a soluble form that plants can absorb.

B
It can make its own food.

C
It lives in the root nodules of leguminous plants.

D
Legumes provide food and shelter to Rhizobium.

Solution

Rhizobia are bacteria that fix nitrogen after becoming established inside root nodules of legumes. Rhizobium cannot make its own food.
Question 3
1 / -0

Read the statements given below and choose the correct option accordingly.

Statement 1: Saprotrophs get food from decaying organic matter.
Statement 2: They release enzymes over decaying organic matter to absorb nutrients.

A
Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.

B
Both statements 1 and 2 are true, but statement 2 is not the correct explanation of statement 1.

C
Statement 1 is true, but statement 2 is false.

D
Both statements 1 and 2 are false.

Solution

Both the given statements are true. Saprotrophs get food from decaying organic matter. They release enzymes over decaying organic matter to absorb nutrients.
Question 4
1 / -0

The process of photosynthesis is represented as:

A + Water → B + Oxygen

What are A and B?

A
A: Carbon dioxide, B: Glucose

B
A: Sodium, B: Sugar

C
A: Glucose, B: Carbon dioxide

D
A: Sugar, B: Calcium

Solution

Carbon dioxide is taken in through the stomata. The product formed is glucose, which is stored in the form of starch in the plant.
Question 5
1 / -0

Which of the following options contains terms that relate to Chlorophyll, Sun, Oxygen and Iodine, respectively?

A
Green pigment, Energy source, Given out in photosynthesis, Starch

B
Energy source, Given out in photosynthesis, Starch, Green pigment

C
Green pigment, Energy source, Starch, Given out in photosynthesis

D
Energy source, Starch, Given out in photosynthesis, Green pigment

Solution

Chlorophyll is a green pigment, sun is the ultimate source of energy, oxygen is given out in photosynthesis, and iodine is used to detect starch.
Question 6
1 / -0

Which organisms form the symbiotic association called Lichen?

A
Plant root + bacteria

B
Plant root + fungus

C
Plant root + algae

D
Algae + fungus

Solution

Lichen is the symbiotic association between algae and fungus. Fungus benefits from algae because it provides food and alga benefits from fungus as it supplies moisture and nutrients and also gives protection to alga.
