Q11

Match List-I with List-II: Pteropsida-Adiantum, Lycopsida-Selaginella, Psilopsida-Psilotum, Sphenopsida-Equisetum

A (A)-(II), (B)-(III), (C)-(I), (D)-(IV)

B (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

C (A)-(II), (B)-(III), (C)-(IV), (D)-(I)

D (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct Answer

Option D

Solution

Pteropsida - Adiantum (fern).

Lycopsida - Selaginella (clubmoss).

Psilopsida - Psilotum (whisk fern).

Sphenopsida - Equisetum (horsetail).

Q12

Which classes of algae possess pigment fucoxanthin and pigment phycoerythrin, respectively?

A Phaeophyceae and Chlorophyceae

B Phaeophyceae and Rhodophyceae

C Chlorophyceae and Rhodophyceae

D Rhodophyceae and Phaeophyceae

Correct Answer

Option B

Solution

Phaeophyceae (brown algae) have fucoxanthin.

Rhodophyceae (red algae) have r-phycoerythrin which reflects red light and absorbs blue light.

Q13

Which of the following statements is true?

A All pteridophytes exhibit haplo-diplontic pattern

B Seed bearing plants follow haplontic pattern

C Most algal genera are diplontic

D Most bryophytes do not have haplo-diplontic life cycle

Correct Answer

Option A

Solution

All pteridophytes exhibit haplo-diplontic pattern with alternation between haploid gametophyte and diploid sporophyte stages, both free-living.

Q14

Identify the pair of heterosporous pteridophytes:

A Selaginella and Salvinia

B Psilotum and Salvinia

C Equisetum and Salvinia

D Lycopodium and Selaginella

Correct Answer

Option A

Solution

Selaginella and Salvinia are heterosporous pteridophytes producing two different kinds of spores.

Psilotum, Lycopodium and Equisetum are homosporous.

Q15

Assertion: The first stage of gametophyte in the life cycle of moss is protonema stage. Reason: Protonema develops directly from spores produced in capsule.

A Both A and R are correct but R is NOT the correct explanation of A

B A is correct but R is not correct

C A is not correct but R is correct

D Both A and R are correct and R is the correct explanation of A

Correct Answer

Option D

Solution

The protonema is indeed the first gametophyte stage in moss, and it does develop directly from spores released from the capsule.

Q16

Match: Chlamydomonas-Alga, Cycas-Gymnosperm, Selaginella-Pteridophyte, Sphagnum-Moss

A (a)-(ii), (b)-(iii), (c)-(i), (d)-(iv)

B (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

C (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

D (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)

Correct Answer

Option C

Solution

Chlamydomonas is alga. Cycas is gymnosperm. Selaginella is heterosporous pteridophyte. Sphagnum is a moss.

Q17

Hydrocolloid carrageen is obtained from:

A Chlorophyceae and Phaeophyceae

B Phaeophyceae and Rhodophyceae

C Rhodophyceae only

D Phaeophyceae only

Correct Answer

Option C

Solution

Carrageen is a hydrocolloid obtained from red algae (Rhodophyceae).

Q18

Which of the following is incorrectly matched?

A Ectocarpus - Fucoxanthin

B Ulothrix - Mannitol

C Porphyra - Floridian Starch

D Volvox - Starch

Correct Answer

Option B

Solution

Ulothrix is a green alga (Chlorophyceae) with starch as reserve food.

Mannitol is the stored food material of Phaeophyceae (brown algae).

Q19

Match plant with life cycle: Spirogyra-haplontic, Fern-sporophyte dominant with prothallus, Funaria-dominant haploid leafy gametophyte, Cycas-dominant diploid sporophyte

A (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

B (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

C (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

D (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)

Correct Answer

Option B

Solution

Spirogyra is haplontic.

Fern (pteridophyte) has dominant diploid sporophyte with prothallus gametophyte.

Funaria (bryophyte) has dominant leafy gametophyte.

Cycas (gymnosperm) has highly reduced gametophyte.

Q20

Chara contains: (a) Chlorophyceae member (b) Food stored as starch (c) Monoecious with oogonium and antheridium (d) Food stored as laminarin (e) Pigments chlorophyll a, c and fucoxanthin

A (c), (d) and (e) only

B (a) and (b) only

C (a), (b) and (c) only

D (a), (c) and (d) only

Correct Answer

Option C

Solution

Chara is a member of Chlorophyceae. Food is stored as starch. Chara is monoecious with oogonium and antheridium.
