chemical element

What chemical element is a part of vital cell of organic compounds?

Compounds of carbon, hydrogen, oxygen and nitrogen form the main components of all organic bodies.

stock material

As a stock material active glycogen accumulates in the cells of

Glycogen is a spare stjck material of animals and fungi. Glucose is converted to glycogen in dog liver cells.

inorganic substances

Inorganic substances of cells include

Water is an inorganic substance and vitamins, carbohydrates and fats are organic substances.


Due to what feature of lipids, they form the basis of the plasma membrane of the cell?

All lipids included in the membrane have amphiphilic properties: they consist of hydrophobic and hydrophilic parts. The presence of the hydrophobic layer is very important to perform the functions of membranes, since it is impermeable to ions and polar compounds.


What organelle produces energy used by cells?

Mitochondria is the energy plant of cells; its main function is oxidation of organic compounds and the use of energy released upon their decomposition in the synthesis of ATP molecules.

organelle 2

What organelle allows the protein biosynthesis in cells?

Ribosomes serve for protein biosynthesis from the amino acids on the matrix based on genetic information.

organelle 3

Which organelle provides synthesis of organic compounds from inorganic materials in the plant cells?

Chloroplasts are the green plastids, which are found in the cells of photosynthetic eukaryotes. With their help, photosynthesis takes place.

organelle 4

What organelle allows the accumulation of waste products in a plant cell?

Vacuoles are single-membraned organelles contained in some eukaryotic cells and performing various functions (secretion, excretion and storage of reserve substances, autophagy, autolysis, etc.).

cell theory

The appearance of cell theory in the middle of the XIX century is associated with the development of

Creating a microscope made it possible to study cells.

cell formation

What cell formation provides the interaction of all of its structures?

Cytoplasm is constantly moving, it flows inside the living cell, moving along with a variety of substances and organelles. Almost all the processes of cellular metabolism take place in it. Among other things, there are insoluble  metabolic wastes and nutrients replacement in the cytoplasm.

organelle 5

In what cell organelle oxidation of organic matter takes place?

The main function of mitochondria is the oxidation of organic compounds and the use of energy released upon their decomposition in the synthesis of ATP molecules.


Onion skin cell and human skin cell contain

Onion skin cells and human skin cells contain mitochondria.
2.4 are signs of plant cell, i.e. human skin cells do not contain it.

Animal cells

Which animal cells are capable of reducing?

Contractility is the property of muscle cells.

plant cell

What is the difference between the old plant cell and the young plant cell?

Older plant cell differs from the young plant cells in that it contains a larger vacuole and the nucleus is displaced.

Organelle 10

In which organelle the oxidation of nutrients and the formation of ATP is taking place?

Mitochondria are the energy plants of cells; the main function is oxidation of organic compounds and the use of energy released upon their decomposition for synthesis of ATP.

genetic information 2

Genetic information in the plant cell is contained in

Chromosomes are located in the cell nucleus concluding the genes. Chromosomes are the main carriers of the genetic material to ensure its transmission from generation to generation.
