My favourite subject is biology. I really like biology lessons. After all, it is so interesting to study the structure of cells, the types of living organisms. I like all sections of biology. At botany, we studied in detail the structure of the cell, plant species. On zoology - species of animals, insects. But most of all I like to study the structure of man. It is interesting to me because it allows me to understand how this or that organ of my body actually works, what it consists of. The subject of biology helped me decide on the choice of profession, I want to become a doctor.
