Question 2 of 15beginner🧠 RememberShort Answer3 marks

Write two major functions each of testis and ovary.

Correct Answer

Functions of Testis:

  1. Production of sperms (Spermatogenesis): The seminiferous tubules contain male germ cells (spermatogonia) which undergo meiotic divisions leading to sperm formation.
  2. Production of hormones: The Leydig cells, located outside the seminiferous tubules, synthesise and secrete testicular hormones called androgens.

Functions of Ovary:

  1. Production of female gamete: The ovaries produce the female gamete called ovum.
  2. Production of hormones: The ovaries produce several steroid hormones (ovarian hormones).

Explanation

The context clearly states the dual functions of both organs. For testis, it mentions spermatogenesis occurring in seminiferous tubules and androgen production by Leydig cells. For ovaries, it explicitly states they 'produce the female gamete (ovum) and several steroid hormones (ovarian hormones)'. This is a straightforward 3-mark question testing knowledge of primary reproductive organ functions.

Solution Steps

  1. Step 1: Identify testis functions from context - sperm production in seminiferous tubules and androgen secretion by Leydig cells

  2. Step 2: Identify ovary functions from context - ovum production and steroid hormone production

  3. Step 3: Present both functions for each organ with proper terminology
