Hint 1

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. (i) Seminal vesicles and prostate gland: their secretions provide nourishment to the sperms, and make the transport of sperms easier by forming a fluid medium.

    1 mark

  2. (ii) Oviduct: it carries the egg from the ovary to the uterus, and it is the site of fertilisation.

    1 mark

  3. (iii) Testis: it produces sperms, and it secretes the hormone testosterone.

    1 mark

Answer: (i) Nourish sperms and ease their transport; (ii) carries the egg to the uterus and is the site of fertilisation; (iii) produces sperms and secretes testosterone.

Where the marks are

  • Seminal vesicles/prostate: nourishment and transport of sperms (½ + ½ mark)
  • Oviduct: carries the egg and is the site of fertilisation (½ + ½ mark)
  • Testis: sperm production and testosterone secretion (½ + ½ mark)
