1. Question 1 (NEET 2026)

   NEET 2026EasyMale and female reproductive systems

   Which of the following struture is not a part of the male reproductive system?

   1. AOption A: Rete testis
   2. BOption B: Epididymis
   3. COption C: Vasa efferentia
   4. DOption D: Infundibulum

   Show answer & explanationHide answer & explanation

   Correct answer: (D) Infundibulum

   Explanation

   The male sex accessory ducts include the rete testis, vasa efferentia, epididymis and vas deferens. Seminiferous tubules open into the vasa efferentia through the rete testis, and the vasa efferentia open into the epididymis. The infundibulum is the funnel-shaped part of the fallopian tube (oviduct) closer to the ovary, with finger-like fimbriae; it belongs to the female reproductive system. Hence the structure not in the male reproductive system is the infundibulum, option (D).

2. Question 2 (NEET 2026)

   NEET 2026MediumMenstrual cycle: ovulation and corpus luteum

   Given below are two statements: Statement I : Ovulation is caused by LH surge leading to rupture of Graafian follicles. Statement II: Graafian follicle remaining after ovulation transform into corpus luteum and secretes large amount of estrogen. 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: (C) Statement I is correct but Statement II is incorrect

   Explanation

   Statement I is correct: both LH and FSH attain a peak in the middle of the cycle (about the 14th day). This rapid secretion of LH (the LH surge) induces rupture of the Graafian follicle and release of the ovum (ovulation). Statement II is incorrect: the remaining parts of the Graafian follicle do transform into the corpus luteum, but the corpus luteum secretes large amounts of progesterone (not estrogen), which is essential for maintaining the endometrium. Hence option (C).

3. Question 3 (NEET 2026)

   NEET 2026MediumGametogenesis

   Spermatogonia undergo a series of cell divisions to produce sperms. Select the correct statements: A. Spermatogonia always undergo meiotic cell division. B. Primary spermatocytes divide mitotically to produce secondary spermatocytes. C. Secondary spermatocytes, through their second meiotic division, produce haploid spermatids. D. Spermatids produce spermatozoa through mitosis. E. Spermatids transform into spermatozoa by spermiogenesis. Choose the correct answer from the options given below:

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

   Show answer & explanationHide answer & explanation

   Correct answer: (B) C and E only

   Explanation

   Secondary spermatocytes undergo meiosis II to form haploid spermatids, and spermatids transform into spermatozoa by spermiogenesis.

4. Question 4 (NEET 2026)

   NEET 2026EasyPlacenta as an endocrine tissue

   Which of the following hormone is not secreted by human placenta?

   1. AOption A: hCG
   2. BOption B: Estrogen
   3. COption C: Progesterone
   4. DOption D: LH

   Show answer & explanationHide answer & explanation

   Correct answer: (D) LH

   Explanation

   The placenta acts as an endocrine tissue and produces several hormones: human chorionic gonadotropin (hCG), human placental lactogen (hPL), estrogens and progestogens. In the later phase of pregnancy, relaxin is secreted by the ovary. Luteinizing hormone (LH) is a gonadotropin secreted by the anterior pituitary, not by the placenta. Hence option (D).

5. Question 5 (NEET 2026)

   NEET 2026MediumPregnancy, Parturition and Lactation

   Match List I with List II related to embryonic development at various months of pregnancy: Choose the correct answer from the options given below:

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

   Show answer & explanationHide answer & explanation

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

   Explanation

   8 weeks → limbs and digits develop; 12 weeks → external genital organs develop; 20 weeks → foetal movements and hair appear; 24 weeks → body covered with fine hair and eyelashes form.

6. Question 6 (NEET 2026)

   NEET 2026EasyOogenesis and membranes of the ovum

   The covering of ovum at ovulation is _________.

   1. AOption A: endometrium
   2. BOption B: zona radiata
   3. COption C: zona pellucida
   4. DOption D: chorion

   Show answer & explanationHide answer & explanation

   Correct answer: (C) zona pellucida

   Explanation

   In the tertiary follicle, the secondary oocyte forms a new membrane called the zona pellucida surrounding it. At ovulation the ovum (secondary oocyte) is released with this zona pellucida layer (and the outer corona radiata cells) around it. During fertilisation the sperm contacts the zona pellucida, which then blocks entry of additional sperms. The endometrium is the inner lining of the uterus, and the chorion is an extra-embryonic membrane formed after implantation. 'Zona radiata' is not the NCERT term (the follicle cell layer is the corona radiata). Hence option (C).

7. Question 7 (NEET 2025)

   NEET 2025MediumFertilisation and Implantation

   Find the correct statements : A. In human pregnancy, the major organ systems are formed at the end of 12 weeks. B. In human pregnancy the major organ systems are formed at the end of 8 weeks. C. In human pregnancy heart is formed after the end of gestation. D. In human pregnancy, limbs and digits develop by the end of second month. E. In human pregnancy the appearance of hair is usually observed in the fifth month. Choose the correct answer from the options given below :

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

   Show answer & explanationHide answer & explanation

   Correct answer: (D) A, C, D and E Only

   Explanation

   In human pregnancy, major organ systems are formed by the end of 12 weeks. Limbs and digits develop by the end of the second month, and appearance of hair is usually observed during the fifth month. Hence statements A, C, D and E are considered correct according to the answer key.

8. Question 8 (NEET 2025)

   NEET 2025EasyMenstrual Cycle

   The first menstruation is called :

   1. AOption A: Menopause
   2. BOption B: Menarche
   3. COption C: Diapause
   4. DOption D: Ovulation

   Show answer & explanationHide answer & explanation

   Correct answer: (B) Menarche

   Explanation

   The first menstrual flow in human females is called menarche. It marks the beginning of reproductive maturity.

9. Question 9 (NEET 2025)

   NEET 2025EasyFlower Morphology and Pollination

   Which of the following is an example of a zygomorphic flower?

   1. AOption A: Petunia
   2. BOption B: Datura
   3. COption C: Pea
   4. DOption D: Chilli

   Show answer & explanationHide answer & explanation

   Correct answer: (C) Pea

   Explanation

   Pea flower exhibits bilateral symmetry and is therefore zygomorphic. Petunia, Datura, and Chilli are actinomorphic flowers.

10. Question 10 (NEET 2024)

    NEET 2024MediumMorphology of Flowering Plants

    Identify the type of flowers based on the position of calyx, corolla and androecium with respect to ovary from the given figures (a) and (b)

    1. AOption A: (a) Perigynous; (b) Epigynous
    2. BOption B: (a) Perigynous; (b) Perigynous
    3. COption C: (a) Epigynous; (b) Hypogynous
    4. DOption D: (a) Hypogynous; (b) Epigynous

    Show answer & explanationHide answer & explanation

    Correct answer: (B) (a) Perigynous; (b) Perigynous

    Explanation

    In figure (a), the ovary is superior and other floral parts arise below it, indicating a hypogynous flower. In figure (b), the ovary is inferior and floral parts arise above it, indicating an epigynous flower.
