The long, multi-statement questions that dominated NEET 2025 & 2026 — each covers 5-6 concepts at once, so they double as fast full-chapter revision.
- Q1. Which of the following statements about Natural Classification Systems, such as that proposed by Bentham and Hooker, are NOT correct? S1. They are primarily based on a few superficial morphological characters, similar to artificial systems. S2. These systems incorporate internal features like ultrastructure, anatomy, embryology, and phytochemistry. S3. They ignore the natural affinities among organisms, focusing solely on observable external traits. S4. Such systems avoid giving equal weightage to vegetative and sexual characters, acknowledging environmental influences on vegetative traits. S5. The classification by George Bentham and Joseph Dalton Hooker for flowering plants is an example of this system.
- Q2. Match the following algal classes with their major pigments and cell wall composition: Column I (Algal Class) A. Chlorophyceae B. Phaeophyceae C. Rhodophyceae Column II (Major Pigments) (i) Chlorophyll a, d, phycoerythrin (ii) Chlorophyll a, b (iii) Chlorophyll a, c, fucoxanthin Column III (Cell Wall Composition) (X) Cellulose, pectin and polysulphate esters (Y) Cellulose and algin (Z) Cellulose and pectose Which of the following represents the correct combination of Algal Class, Major Pigments, and Cell Wall Composition?
- Q3. Arrange the following events of sexual reproduction in bryophytes in the correct sequential order, starting from the establishment of the gametophyte: (i) Formation of haploid gametophyte from germinating spores. (ii) Production of multicellular antheridia and archegonia on the gametophyte. (iii) Release of biflagellate antherozoids and a single egg. (iv) Fusion of antherozoid and egg in water, leading to zygote formation. (v) Development of a multicellular sporophyte from the zygote, attached to the gametophyte. (vi) Meiosis in sporophyte cells to produce haploid spores.
- Q4. Match the following columns correctly regarding examples and characteristics of Pteridophytes. Column I (Pteridophyte) A. Lycopodium B. Selaginella C. Equisetum D. Dryopteris Column II (Class) i. Psilopsida ii. Lycopsida iii. Sphenopsida iv. Pteropsida Column III (Key Characteristic) p. Precursor to seed habit q. Dominant sporophyte with true roots, stem, and leaves r. Sporophylls form compact strobili s. Homosporous in nature

Which one of the following statements is wrong?
- A. Algae increase the level of dissolved oxygen in the immediate environment
- B. Algin is obtained from red algae, and carrageenan from brown algae
- C. Agar - agar is obtained from Gelidium and Gracilaria
- D. Laminaria and Sargassum are used as food
Explanation: Answer: (B) Algin is obtained from red algae, and carrageenan from brown algae. Solution: This is the WRONG statement, hence the correct choice. NCERT clearly states the opposite: algin is obtained from BROWN algae and carrageen (carrageenan) from RED algae. The other statements are all true — algae are photosynthetic and raise dissolved oxygen, agar is obtained from Gelidium and Gracilaria, and Laminaria and Sargassum are used as food. NCERT Reference: Class XI Biology, Plant Kingdom, p.26, lines 10-13 — "produce large amounts of hydrocolloids (water holding substances), e.g., algin (brown algae) and carrageen (red algae) which are used commercially. Agar, one of the commercial products obtained from Gelidium and Gracilaria".
Which of the following is incorrectly matched?
- A. Ectocarpus - Fucoxanthin
- B. Ulothrix - Mannitol
- C. Porphyra - Floridian Starch
- D. Volvox - Starch
Explanation: Answer: (B) Ulothrix - Mannitol. Solution: Ulothrix is a green alga (Chlorophyceae) and its stored food is starch, not mannitol; mannitol is the reserve carbohydrate of brown algae (Phaeophyceae), so the Ulothrix–Mannitol pairing is incorrect. The other pairs are correct: Ectocarpus (Phaeophyceae) bears the pigment fucoxanthin, Porphyra (Rhodophyceae) stores floridean starch, and Volvox (Chlorophyceae) stores starch. NCERT Reference: Class XI Biology, Plant Kingdom, p.27, lines 3-4 — "Food is stored as complex carbohydrates, which may be in the form of laminarin or mannitol".
Which of the following statements is true?
- A. Most algal genera are diplontic
- B. Most bryophytes do not have haplo-diplontic life cycle
- C. All pteridophytes exhibit haplo-diplontic pattern
- D. Seed bearing plants follow haplontic pattern
Explanation: Answer: (C) All pteridophytes exhibit haplo-diplontic pattern. Solution: In pteridophytes both the multicellular diploid sporophyte and the multicellular haploid gametophyte (prothallus) are independent and free-living, which defines the haplo-diplontic life cycle; hence option C is true. Most algal genera are haplontic (not diplontic), bryophytes are haplo-diplontic (so the statement that they do not have it is false), and seed-bearing plants follow the diplontic (not haplontic) pattern. NCERT Reference: Class XI Biology, Plant Kingdom (Plant Life Cycles & Alternation of Generations — content rationalised from current reprint, grounded in pre-2023 NCERT text). The current reprint retains the supporting facts that pteridophytes have an independent free-living sporophyte and a free-living prothallus gametophyte at p.32, lines 12-13 ("Zygote thereafter produces a multicellular well-differentiated sporophyte which is the dominant phase of the pteridophytes") and p.31-32 ("free-living, mostly photosynthetic thalloid gametophytes called prothallus").
Conifers are adapted to tolerate extreme environmental conditions because of
- A. Broad hardy leaves
- B. Superficial stomata
- C. Thick cuticle
- D. Presence of vessels
Explanation: Answer: (C) Thick cuticle. Solution: Conifers face extremes of temperature, humidity and wind, and survive by minimising water loss. Their needle-like leaves reduce surface area while a thick cuticle and sunken (not superficial) stomata cut transpiration; hence the adaptive feature is the thick cuticle. Broad hardy leaves and superficial stomata are wrong as conifers have needle-like leaves and sunken stomata, and gymnosperms (the conifer group) lack vessels in their xylem (vessels are a typical angiosperm feature). NCERT Reference: Class XI Biology, Plant Kingdom, p.32, lines 40-42 — "In conifers, the needle-like leaves reduce the surface area. Their thick cuticle and sunken stomata also help to reduce water loss."
