Give examples of cells and tissues where single-membrane organoids are most well developed. Explain what it is connected with.

A well-developed Golgi apparatus is present in the secretory cells of the glands, as well as in the cells of the liver and kidneys. The Golgi complex has many important functions. Through the channels of the endoplasmic reticulum, the products of the synthetic activity of the cell — proteins, carbohydrates and fats — are transported to it. All these substances first accumulate, and then in the form of large and small vesicles enter the cytoplasm and are either used in the cell itself in the process of its vital activity, or are removed from it and used in the body. For example, in the cells of mammalian pancreas, digestive enzymes are synthesized, which accumulate in the cavities of an organoid.
Vacuoles are especially noticeable in plant cells: in many mature plant cells, they make up more than half the cell volume. One of the important functions of plant vacuoles is the accumulation of ions and the maintenance of turgor (turgor pressure).
Vacuole is a place of supply of water. Plant vacuoles are filled with colorless or colored cell sap.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
