Describe the structure of human sperm with a well-labelled diagram.
Show Hint
Solution and Explanation
Step 1: Overview of the Sperm Structure. - The human sperm is a microscopic, motile cell with three main parts: head, middle piece, and tail.
Step 2: Describe Each Part. - Head: Contains the nucleus with the genetic material (haploid DNA). It is covered by a cap-like structure called the acrosome, which contains enzymes to penetrate the egg during fertilization. - Middle Piece: Contains mitochondria that provide energy for the sperm's movement. - Tail (Flagellum): A long whip-like structure that enables the sperm to swim towards the egg.
Final Answer: The human sperm consists of a head (with genetic material and acrosome), middle piece (with mitochondria), and a tail (for motility).

- Read the following passage carefully and answer the questions that follow:
The Indian National Army plans went away with the defeat of Japan. Subhash Bose was killed in a plane accident while on his way to Tokyo. It is true that many leaders did not like the idea of India winning freedom with the assistance of a country like Japan and her fascist allies. But during the closing years of the war, Subhash Bose and the Indian National Army served to hold up the dropping spirits of the nationalist Indians at home, who were feeling helpless and frustrated. They set before all sections of the Indian people, including those serving in the army, an example of courage and patriotism which was both inspiring and ennobling. Therefore, when the Government announced their decision to prosecute some of the Indian National Army officers for treason because they had broken their oath of loyalty to the British crown, there was a wave of nationalist protest. There were massive demonstrations all over the country. There were persistent demands that the officers should be released.
