Скачать или смотреть The cell is the basic structural and functional unit of life forms.

The cellular structure is a feature of all living organisms. Since all living organisms are very diverse - these are fungi, plants, and animals - then the cells of all of them are different. At the same time, all cells of living organisms have common structural features, which we will consider in today's lesson.
All cells of living organisms have three main parts:
1) Kernel.
2) Cytoplasm.
3) Cell membrane.
Let's consider each education in more detail.
The nucleus is most often a round formation. It contains all the hereditary information of the cell, necessary for its life and functioning.
Cytoplasm is a structure located between the nucleus and the cell membrane. It contains many formations that perform various functions in the cell. For example:
1) Ribosomes - are involved in the formation of proteins.
2) Chloroplasts - contain chlorophyll, which is involved in the transformation of inorganic substances into organic ones.
3) Vacuole - contains a supply of nutrients for the cell, or accumulates substances unnecessary for the cell.
The cell membrane covers the outside of the cell and protects its contents from environmental influences. All cells in the body are interconnected through pores located in the cell membrane.
Plant cells have a solid cell wall outside the cell membrane that gives the cells their shape.
All living organisms are divided into unicellular and multicellular.
Unicellular - their body is a single cell.
Multicellular organisms are made up of many cells.
The cells of multicellular organisms are very diverse and perform various specialized functions. Depending on the similarity, they form tissues.
