Reproductive System JSS1 Basic Science Lesson Note

DEFINITION

Reproduction is the ability of living things to produce offspring like themselves. Reproduction is one of the characteristics of living things, which is for the continuation of life.

There are two types of reproduction. These are

1. Asexual reproduction
2. Sexual reproductionAsexual reproduction—this kind of reproduction involves a single parent to produce young ones. In asexual reproduction, the individual grows and splits into two and this process continues. Examples are binary fission, vegetative reproduction (as in potato, cassava, yam, etc.), and so onSexual reproduction – this is the kind of reproduction that involves two sexes. The male produces a sex cell and the female does that too. This is the most common means of reproduction in animals but is also found in plants.

THE MALE REPRODUCTIVE SYSTEM

The male reproductive system is made up of organs found both outside and inside the body. Such as the penis, scrotum, testes, etc.

The male sex cell is called the sperm. This is what fusses with the female sex cell at fertilization.

The following are the male reproductive organs, their location, and their respective functions

THE FEMALE REPRODUCTIVE SYSTEM

The female reproductive system is made up of both external and internal organs that are used for reproductive processes. Examples are the ovary, vagina, fallopian tube, etc.

The following are the female reproductive organs, their location, and their respective functions

Care of the female reproductive organs

1.     Bath at least twice daily
2.     Avoid taking illegal drugs
3.     Use clean toilets
4.     Wear clean and neat panties
5.     Visit the gynecologist in case of any abnormalities

Care of the male reproductive organs

1.     Bath daily
2.     Avoid tight underwear and clothing
3.     Eat a healthy and balanced diet
4.     Wear protective gear when playing contact sports
