Class 10 Concise ICSE Biology Selina Solutions with Hint Ch-6

Que-1: Chlorophyll is located in :

1. Stroma
2. Thylakoid
3. Stoma
4. Fret

Sol: Thylakoid

Hint:  disc shaped Chlorophyll (granum) occur in stroma of chloroplast

Que-2: Which of the following is not applicable to the process of photosynthesis ?

1. Oxygen is evolved
2. Carbon dioxide is absorbed
3. Carbon dioxide is evolved
4. Water is utilized

Sol: Carbon dioxide is evolved

Hint:  During photosynthesis, carbon dioxide and water is raw material while oxygen and glucose is by-product.

Que-3: The colour of VIBGYOR spectrum which is reflected by chlorophyll is:

1. Blue
2. Green
3. Red
4. Yellow

Sol: Green

Hint: leaf looks green it means only green is reflected to our eye while other are absorbed

Que-4: The basic functional unit of solar energy which is absorbed by the pigment chlorophyll is:

1. Proton
2. Phytochrome
3. Phyton
4. Photon

Sol: Photon

Hint: Photon is the bundle of energy in least possible amount

Que-5: The molecules of water split during:

1. Photorespiration
2. Phosphorylation
3. Photolysis
4. Photophosphorylation

Sol: Photolysis

Hint: Photolysis define as Thylakoid absorbs solar energy in form of bundle (photon) to split the water molecule

Que-6: The granum is a pile of many

1. Frets
2. Stoma
3. Stroma
4. Thylakoids

Sol: Thylakoids

Hint: in Chloroplast section thylakoids are stacked in a group This group of thylakoid is called granum.

Que-7: Which of the following is used to remove chlorophyll from the leaves:

1. Iodine solution
2. Methylated spirit
3. Potassium hydroxide
4. Soda lime

Sol: Methylated spirit

Hint: The leaf is boiled in Methylated spirit to remove chlorophyll.

Que-8: The raw material which is reduced during photosynthesis is :

1. Carbon dioxide
2. Glucose
3. Water
4. Oxygen

Sol: Carbon dioxide

Hint: water is oxidised, which means it loses electrons, but carbon dioxide is reduced, which means it gains electrons. Carbon dioxide is converted to glucose, while water is turned to oxygen

Que-9: The optimum temperature for the process of photosynthesis is

1. 53°C
2. 45°C
3. 25°C
4. 35°C

Sol: 35°C

Hint: The rate of photosynthesis is maximum at 35°C and falls below / above 35

Que-10: Conversion of several glucose molecules into starch is termed as

1. Photolysis
2. Phosphorylation
3. Polymerisation
4. Photorespiration

Sol: Polymerisation

Hint: Polymerisation is the process by which simple monomers (glucose) join to form complex polymers (starch).
