1. Question 1 (NEET 2026)

   NEET 2026EasyBinomial nomenclature

   Which of the following statements is not true about the universal rules of binomial nomenclature?

   1. AOption A: Biological names are generally in Latin
   2. BOption B: Both words in a biological name, when handwritten, are separately underlined or printed in italics
   3. COption C: The specific epithet in the biological name starts with a small letter
   4. DOption D: The first word in the biological name represents the specific epithet, while the second component denotes the genus

   Show answer & explanationHide answer & explanation

   Correct answer: (D) The first word in the biological name represents the specific epithet, while the second component denotes the genus

   Explanation

   In binomial nomenclature, the first word denotes the genus (capitalized) and the second word denotes the specific epithet (lowercase). Therefore statement (4) is incorrect.

2. Question 2 (NEET 2026)

   NEET 2026MediumTaxonomic categories of mango

   Match List-I with List-II. List-I: A. Family B. Genus C. Class D. Phylum E. Order List-II: I. Sapindales II. Dicotyledonae III. Anacardiaceae IV. Angiospermae V. Mangifera Choose the correct answer from the options given below :

   1. AOption A: A-I, B-V, C-II, D-IV, E-III
   2. BOption B: A-II, B-I, C-III, D-IV, E-V
   3. COption C: A-II, B-III, C-V, D-I, E-IV
   4. DOption D: A-III, B-V, C-II, D-IV, E-I

   Show answer & explanationHide answer & explanation

   Correct answer: (D) A-III, B-V, C-II, D-IV, E-I

   Explanation

   The official key marks option (D) with an asterisk and the note "Conceptual errata". NCERT Table 1.1 gives the taxonomic categories of mango (Mangifera indica): Genus Mangifera, Family Anacardiaceae, Order Sapindales, Class Dicotyledonae and Division Angiospermae. So A. Family – III. Anacardiaceae, B. Genus – V. Mangifera, C. Class – II. Dicotyledonae, D. Phylum – IV. Angiospermae and E. Order – I. Sapindales, i.e. A-III, B-V, C-II, D-IV, E-I, which is option (D). The conceptual slip is most likely in List-I: for plants the category above class is called Division, not Phylum (Phylum is used for animals), so Angiospermae is strictly a division. Option (D) is still the only correct matching.

3. Question 3 (NEET 2026)

   NEET 2026EasyTaxonomic hierarchy of categories

   Arrange the following taxonomic categories in ascending order. (a) Genus (b) Class (c) Order (d) Phylum (e) Family (f) Kingdom (g) Species Choose the correct answer from the options given below :

   1. AOption A: (g), (a), (e), (c), (b), (d), (f)
   2. BOption B: (a), (c), (d), (g), (f), (b), (e)
   3. COption C: (g), (c), (d), (b), (e), (a), (f)
   4. DOption D: (f), (c), (b), (g), (d), (e), (a)

   Show answer & explanationHide answer & explanation

   Correct answer: (A) (g), (a), (e), (c), (b), (d), (f)

   Explanation

   In the taxonomic hierarchy, the lowest category is species and the highest is kingdom. In ascending order: Species → Genus → Family → Order → Class → Phylum → Kingdom That is (g) → (a) → (e) → (c) → (b) → (d) → (f), which is option (A).

4. Question 4 (NEET 2026)

   NEET 2026EasyTaxonomic category: genus

   Genus represents __________.

   1. AOption A: an individual plant or animal
   2. BOption B: a population of plants and animals
   3. COption C: a group of closely related species
   4. DOption D: a group of closely related families

   Show answer & explanationHide answer & explanation

   Correct answer: (C) a group of closely related species

   Explanation

   According to NCERT, a genus comprises a group of related species which has more characters in common in comparison to species of other genera. For example, potato, tomato and brinjal are different species of the genus Solanum. A group of related genera forms a family, and a group of closely related families would be an order. Hence the answer is option (C).

5. Question 5 (NEET 2025)

   NEET 2025HardAnimal Kingdom

   While trying to find out the characteristic of a newly found animal, a researcher did the histology of adult animal and observed a cavity with presence of mesodermal tissue towards the body wall but no mesodermal tissue was observed towards the alimentary canal. What could be the possible coelome of that animal?

   1. AOption A: Acoelomate
   2. BOption B: Pseudocoelomate
   3. COption C: Schizocoelomate
   4. DOption D: Spongocoelomate

   Show answer & explanationHide answer & explanation

   Correct answer: (B) Pseudocoelomate

   Explanation

   In pseudocoelomates, mesoderm lines the body wall but not the alimentary canal completely.

6. Question 6 (NEET 2025)

   NEET 2025HardPteridophyte Life Cycle

   Given below are the stages in the life cycle of pteridophytes. Arrange the following stages in the correct sequence. A. Prothallus stage B. Meiosis in spore mother cells C. Fertilisation D. Formation of archegonia and antheridia in gametophyte E. Transfer of antherozoids to the archegonia in presence of water Choose the correct answer from the options given below:

   1. AOption A: B, A, D, E, C
   2. BOption B: B, A, E, C, D
   3. COption C: D, E, C, A, B
   4. DOption D: E, D, C, B, A

   Show answer & explanationHide answer & explanation

   Correct answer: (A) B, A, D, E, C

   Explanation

   In pteridophytes, meiosis forms spores, spores develop into prothallus, gametophytes produce archegonia and antheridia, antherozoids transfer through water, and fertilisation occurs.

7. Question 7 (NEET 2025)

   NEET 2025MediumBryophytes

   The correct sequence of events in the life cycle of bryophytes is A. Fusion of antherozoid with egg. B. Attachment of gametophyte to substratum. C. Reduction division to produce haploid spores. D. Formation of sporophyte. E. Release of antherozoids into water. Choose the correct answer from the options given below:

   1. AOption A: D, E, A, C, B
   2. BOption B: B, E, A, C, D
   3. COption C: B, E, A, D, C
   4. DOption D: D, E, A, B, C

   Show answer & explanationHide answer & explanation

   Correct answer: (C) B, E, A, D, C

   Explanation

   Bryophyte life cycle proceeds as: attachment of gametophyte to substratum, release of antherozoids into water, fertilization, formation of sporophyte, and finally meiosis to produce haploid spores.
