Chloroplast is a type of organelle present in the cells of plants and eukaryotic algae. The process of photosynthesis takes place inside these organelles: light energy is captured by chlorophyll pigments (and not only) and converted into chemical energy (ATP and NADPH).

lysosome present in numerous copies in eukaryotic cells and represents the digestive system of the cell as it is responsible for the degradation and digestion (destruction) of foreign molecules and macromolecules ingested by the cell.

Centrioles are found in pairs and are usually arranged at right angles to each other. Together with an electron-dense material surrounding them, called "pericentriolar material".

The centriole is an organelle present in most cells, in some fungi, algae and lower plants. It is absent in Tracheophytes.

Photosynthesis is essential for humans and for all living beings, because it produce oxigen and other important substance

Cytoplasm refers to the part of the cell inside the cell membrane consisting of a fluid matrix ( cytosol ) in which cellular organelles are dispersed. In both eukaryotic and prokaryotic cells , the cytoplasm also contains a framework formed by a complex network of filaments made of fibrous and/or globular proteins that constitute the cytoskeleton.

Ribosomes are macromolecular complexes, immersed in the cytoplasm or anchored to the rough endoplasmic reticulum or contained in other organelles (mitochondria and chloroplasts), responsible for protein synthesis. Their function is to read the information contained in the messenger RNA (m-RNA) chain. They are membrane-free organelles.

The cell is the smallest living unit. There are organisms formed by a single cell and organisms formed by many cells. Cells are made of organic molecules,they grow,differentiate and multiply.There are two types of cells:eukariotic and prokaryotic cells.The eukariotic cells are divided into animal cells and plant cells.

The cell

Mitochondria are the site of aerobic cellular respiration, which generates adenosine triphosphate (ATP) that is used throughout the cell as a source of chemical energy.

Plant cells, like animal cells, are made up of a nucleus and cytoplasm, a gelatinous substance rich in organelles. The nucleus contains the genetic material, DNA, where all the information for the functioning of the organism is stored.

Ribosomes are macromolecular complexes, immersed in the cytoplasm or anchored to the rough endoplasmic reticulum or contained in other organelles (mitochondria and chloroplasts), responsible for protein synthesis.

The characteristic presence of numerous vacuoles (not organelles but intracellular cavities) which occupy a large part of the cell and whose main function is to maintain cellular turgidity.

The Golgi apparatus is an organelle of lipoprotein composition discovered in 1898 by the Italian physician and microscopist Camillo Golgi, who identified it as a delicate structure located in the cell in a paranuclear position. Golgi gave the organelle the name of internal reticular apparatus.

The presence of the cell wall made up of cellulose (a polymer whose elementary unit is glucose, proteins and, following modifications, lignin, suberin...) and the related plasmodesmata, channels in the cell wall thanks to which the plant cells communicate with each other.

Photosynthesis is a chemical process by which green plants and other organisms produce organic substances – mainly carbohydrates – from the first reagent, atmospheric carbon dioxide and metabolic water , in the presence of sunlight , falling within the processes of carbohydrate anabolism , completely opposite to the reverse processes of catabolism .
