General information 1 The bodies of all living organisms are made up of cells. Most animal bodies are made up of many cells.
General information 2 There are organisms whose bodies consist of only one cell - these are bacteria, unicellular algae, fungi, and protozoa.
General information 3 The science of CYTOLOGY studies the structure, development and activity of cells.
General information 4 Most animal cells are very small. The shapes of animal cells are very different. Muscle cells Blood cells Skin cells The shape and size of animal cells depend on the function of the cell

Tissue is a group of cells similar in structure and function and the intercellular substance secreted by these cells.
Epithelial (cover) tissue Connective tissue Muscle Nervous tissue Tissues
Epithelial tissue Forms the integument of animals, lining body cavities and internal organs; They consist of one or several layers of tightly adjacent cells and contain almost no intercellular substance;
Connective tissue Consists of a small number of cells scattered in a mass of intercellular substance; It is part of the skeleton, supports the body, creates support, and protects internal organs.
Muscle tissue Consists of elongated cells that receive irritation from the nervous system and respond to it with irritation; Through contraction and relaxation skeletal muscles animal movement occurs.
Nervous tissue forms nervous system, which consists of nerve cells– neurons; Neurons have a stellate shape, long and short processes. Neurons perceive irritation and transmit excitation to muscles, skin, and other tissues and organs.

Structural Features An animal cell does not have a dense cell wall. It lacks vacuoles characteristic of plants and some fungi. As a backup energetic substance The polysaccharide glycogen usually accumulates. Unlike other cells, an animal has a special organelle - a cell center.
Slide 4
Cell wall The outer layer of the surface of animal cells, unlike the cell walls of plants, is very thin and elastic. It is not visible under a light microscope and consists of a variety of polysaccharides and proteins. The surface layer of animal cells is called the glycocalyx. The glycocalyx performs primarily the function of direct connection of animal cells with external environment, with all the substances surrounding it. Having a small thickness (less than 1 micron), the outer layer of animal cells does not play a supporting role, which is characteristic of plant cell walls. The formation of the glycocalyx, as well as the cell walls of plants, occurs due to the vital activity of the cells themselves.
Slide 5
Cellular center Centrioles are a 500 nm hollow cylinder formed by nine triplets of fibrillar protein. Each triplet is connected to the others by a “handle”. One centriole in the diplosome is the mother centriole and carries additional structures: satellites - the foci of microtubule convergence and additional microtubules that form the centrosphere. Centrioles are involved in cell division. The satellites form the filaments of the spindle. After the free ends of the spindle filaments are attached to the primary constriction of the chromosomes, the chromosomes are stretched to the poles of the cell due to the movement of the centrioles.
Slide 1
The structure of an animal cell
Cell membrane. located under the cell wall.
- limits the contents of the cell;
- protects the cell;
- regulates metabolism with the external environment.
Cytoplasm is the viscous fluid that fills the cell; neighboring cells are connected to each other through the cytoplasm.
- accumulation of cell waste products;
- storage of nutrients.
Core. contains chromosomes; covered with a shell.
- participates in the storage and transmission of hereditary information to offspring;
- regulates all processes in the cell.
A nucleolus is an accumulation of nuclear substance in the nucleus.
Functions: participates in the formation of ribosomes.
Ribosomes are round in shape and small in size; located freely in the cytoplasm or attached to the endoplasmic reticulum.
Functions: formation (synthesis) of proteins.
The endoplasmic reticulum (ER) consists of tubules that form a network; has its own shell.
- formation of organic substances (proteins, fats and carbohydrates);
- transport of substances in the cell.
The Golgi apparatus consists of tubules, cavities and vesicles; covered with its own shell.
- formation of complex organic substances;
- formation of lysosomes.
Lysosomes are small vesicles; contains enzymes; have their own shell.
Functions: breakdown of organic substances (proteins, fats, carbohydrates).
Mitochondria have oval shape; covered with a double shell; inner shell forms folds.
Functions: formation and accumulation of energy (“energy stations” of the cell).
The cell center consists of two parts that have a cylindrical shape
Functions: participation in cell division
