1. Question 1 (NEET 2026)

   NEET 2026EasyGymnosperms

   In which one of the following, the ovules are not enclosed by an ovary wall and remain exposed?

   1. AOption A: Funaria
   2. BOption B: Pinus
   3. COption C: Selaginella
   4. DOption D: Wolffia

   Show answer & explanationHide answer & explanation

   Correct answer: (B) Pinus

   Explanation

   Gymnosperms have naked ovules not enclosed within an ovary. Pinus is a gymnosperm. Hence option (B) is correct.

2. Question 2 (NEET 2026)

   NEET 2026EasyGymnosperms: gametophytes and naked seeds

   Given below are two statements: Statement I: In gymnosperms, the male and female gametophytes remain within the sporangia. Statement II: In gymnosperms, seeds are not covered. In the light of the above statements, choose the most appropriate answer from the options given below:

   1. AOption A: Both Statement I and Statement II are correct
   2. BOption B: Both Statement I and Statement II are incorrect
   3. COption C: Statement I is correct but Statement II is incorrect
   4. DOption D: Statement I is incorrect but Statement II is correct

   Show answer & explanationHide answer & explanation

   Correct answer: (A) Both Statement I and Statement II are correct

   Explanation

   Statement I is correct: unlike bryophytes and pteridophytes, in gymnosperms the male and female gametophytes do not have an independent free-living existence; they remain within the sporangia retained on the sporophyte. Statement II is correct: gymnosperms (gymnos = naked, sperma = seeds) have ovules that are not enclosed by any ovary wall, so the seeds that develop after fertilisation are not covered (naked). Both statements are correct, which is option (A).

3. Question 3 (NEET 2026)

   NEET 2026EasyClassification of pteridophytes

   Sphenopsida class belongs to _____________.

   1. AOption A: bryophytes
   2. BOption B: angiosperms
   3. COption C: gymnosperms
   4. DOption D: pteridophytes

   Show answer & explanationHide answer & explanation

   Correct answer: (D) pteridophytes

   Explanation

   NCERT states that pteridophytes are further classified into four classes: Psilopsida (Psilotum), Lycopsida (Selaginella, Lycopodium), Sphenopsida (Equisetum) and Pteropsida (Dryopteris, Pteris, Adiantum). So Sphenopsida, the class of horsetails such as Equisetum, belongs to the pteridophytes, which is option (D).

4. Question 4 (NEET 2022)

   NEET 2022HardAngiosperms

   Match the plant with the kind of life cycle it exhibits:

   1. AOption A: (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
   2. BOption B: (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
   3. COption C: (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
   4. DOption D: (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

   Show answer & explanationHide answer & explanation

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

   Explanation

   Spirogyra has dominant haploid gametophyte; fern has dominant sporophyte with prothallus; Funaria has dominant leafy gametophyte; Cycas has dominant sporophyte with reduced female gametophyte.

5. Question 5 (NEET 2018)

   NEET 2018MediumAlgae

   Which one is wrongly matched?

   1. AOption A: Uniflagellate gametes — Polysiphonia
   2. BOption B: Biflagellate zoospores — Brown algae
   3. COption C: Unicellular organism — Chlorella
   4. DOption D: Gemma cups — Marchantia

   Show answer & explanationHide answer & explanation

   Correct answer: (A) Uniflagellate gametes — Polysiphonia

   Explanation

   Polysiphonia is a red alga in which gametes are non-motile and non-flagellated. Brown algae produce biflagellate zoospores, Chlorella is unicellular, and Marchantia possesses gemma cups. Hence, option (A) is wrongly matched.

6. Question 6 (NEET 2018)

   NEET 2018EasyGymnosperms

   Winged pollen grains are present in

   1. AOption A: Mustard
   2. BOption B: Cycas
   3. COption C: Pinus
   4. DOption D: Mango

   Show answer & explanationHide answer & explanation

   Correct answer: (C) Pinus

   Explanation

   Pinus pollen grains possess wing-like air sacs that help in wind pollination. Mustard, Cycas and Mango do not have winged pollen grains. Hence, option (C) is correct.

7. Question 7 (NEET 2018)

   NEET 2018MediumGymnosperms

   Which of the following statements is correct?

   1. AOption A: Ovules are not enclosed by ovary wall in gymnosperms
   2. BOption B: Selaginella is heterosporous, while Salvinia is homosporous
   3. COption C: Stems are usually unbranched in both Cycas and Cedrus
   4. DOption D: Horsetails are gymnosperms

   Show answer & explanationHide answer & explanation

   Correct answer: (A) Ovules are not enclosed by ovary wall in gymnosperms

   Explanation

   Gymnosperms bear naked ovules that are not enclosed within an ovary wall. Selaginella and Salvinia are both heterosporous, Cedrus has branched stems, and horsetails are pteridophytes. Hence, option (A) is correct.

8. Question 8 (NEET 2016)

   NEET 2016EasyGymnosperms

   Conifers are adapted to tolerate extreme environmental conditions because of:

   1. AOption A: Broad hardy leaves
   2. BOption B: Superficial stomata
   3. COption C: Thick cuticle
   4. DOption D: Presence of vessels

   Show answer & explanationHide answer & explanation

   Correct answer: (C) Thick cuticle

   Explanation

   Conifers possess needle-like leaves with thick cuticle and sunken stomata which help reduce water loss and withstand harsh conditions. Hence option (C) is correct.

9. Question 9 (NEET 2016)

   NEET 2016MediumAlgae

   Which one of the following statements is wrong?

   1. AOption A: Algae increase the level of dissolved oxygen in the immediate environment
   2. BOption B: Algin is obtained from red algae, and carrageenan from brown algae
   3. COption C: Agar-agar is obtained from Gelidium and Gracilaria
   4. DOption D: Laminaria and Sargassum are used as food

   Show answer & explanationHide answer & explanation

   Correct answer: (B) Algin is obtained from red algae, and carrageenan from brown algae

   Explanation

   Algin is obtained from brown algae while carrageenan is obtained from red algae. Thus the statement given in option (B) is incorrect. Hence option (B) is correct.

10. Question 10 (AIPMT 2014)

    AIPMT 2014EasyBryophytes

    Which of the following is responsible for peat formation?

    4. DOption D: Sphagnum

    Show answer & explanationHide answer & explanation

    Correct answer: (D) Sphagnum

    Explanation

    Sphagnum moss accumulates in waterlogged conditions and forms peat, which is widely used as a fuel and soil conditioner.
