Answer 2

Similarities between spermatozoa and egg cells:

1. Both spermatozoa and egg cells are reproductive cells involved in sexual reproduction. 2. They are both haploid cells, meaning they contain half the number of chromosomes compared to other cells in the body. 3. Both spermatozoa and egg cells are produced through a process called meiosis, which ensures the halving of the chromosome number.

Differences between spermatozoa and egg cells:

1. Size and shape: Spermatozoa are typically smaller and have a streamlined shape, allowing them to swim towards the egg. On the other hand, egg cells are larger and rounder in shape, providing ample space for the fertilized embryo to develop. 2. Mobility: Spermatozoa are highly motile and have a tail-like structure called a flagellum that allows them to swim towards the egg. Egg cells, on the other hand, are non-motile and remain stationary within the female reproductive system. 3. Quantity: Spermatozoa are produced in large numbers by the male reproductive system, while egg cells are produced in limited quantities by the female reproductive system. In fact, females are born with a finite number of egg cells, which gradually decrease over time. 4. Function: The main function of spermatozoa is to fertilize the egg cell, combining their genetic material to form a zygote. Egg cells, on the other hand, provide the necessary environment and nutrients for the development of the embryo after fertilization. 5. Structure: Spermatozoa have a head region containing the genetic material (DNA), a midpiece containing mitochondria for energy production, and a tail for locomotion. Egg cells have a nucleus containing the genetic material, cytoplasm rich in nutrients, and protective layers such as the zona pellucida.
