ribosome:ribosome are the granules like structure present on endoplasmic reticulam.

endoplasmic reticulum:the network of membranes is known as endoplasmic reticulum.function of the endoplasmic reticulum is to serve as channels for the transport of materials(especially protiens)betwen various regions of the cytoplasm or between the cytoplasm or nucleus .

hope this answer helps you:))

1.The cell membrane defines the shape and size of the cell.it encloses the cytoplasm and protects it from  the external environment.it maintains a crucial role in maintaining cell balance.
2.the nucleus regulates and controls all the functions of a cell and determines the characteristics of the organism.it consists the genetic material.it involves in cell division.
3.Ribosomes are the sites of proteins.
4.Rough e.r is the site of protein manufacture.the ser helps in manufacture of fat globules,lipids etc.it serves as channels for the transport of materials betweeen various regions of the cytoplasm.
5.mitochondria are responsible for cellular respiration ,a process through which the cell derives its energy to do work.it is also called as 'power house of the cell'.
