Mitochondria are known as the powerhouse of the cell because they are responsible for the release of energy from food ,i.e, cellular respiration. This energy is released in the form of ATP (adenosine triphosphate), the energy currency of the cell.

The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus.

It has been likened to the cell's post office. A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.

Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.

Cilia and flagella are cell organelles that are structurally similar but are differentiated based on their function and/or length. Cilia are short and there are usually many (hundreds) cilia per cell. On the other hand, flagella are longer and there are fewer flagella per cell (usually one to eight).

onon the basis of the number of cells organism are classified as unicellular and multicellular. unicellularunicellular organisms are those who possesses only one cell and all the basic functions are performed by the single cell body.
multicellular multicellular organisms are those organisms fridge have more than two cell and there is a division of labour between cells and cells are organised and tissues tissues and organ systems organ systems to organs.

A high-quality egg has only a small air cell. The yolk is well-centered in the albumen and is surrounded by the vitelline membrane, which is colorless. The germinal disc, where fertilization takes place, is attached to the yolk. ... The shell contains several thousand pores that permit the egg to "breathe."I am sorry I cannot provide you a diagram.

cell wall is permeable membrane which is present in plant and fungi cell. in plants cell it is made up of cellulose and in fungi it is made up of Chitin. cell wall allows all the particles to pass through it. it also turgids the cell during endo and eggs osmosis.
cell membrane is selectively permeable membrane present in all types of cell. it allows only all solvents and few solutes to 0ass through it.
