It contains DNA which acts as a blueprint for the manufacture of proteins

Involved in the synthesis of RNA

It is the site of production of energy-rich ATP by aerobic respiration

It contains the green pigment chlorophyll to trap light energy for the process of photosynthesis

It is made of cellulose and gives strength and support to plant cells. It is freely permeable ie allows substances to pass through it with ease

It is involved in the transport of proteins for export from the cell

It is the site of protein synthesis

They are involved in the formation of spindle fibres during mitosis and meiosis

It is a sac containing water and dissolved substances. It also contributes to cell turgor and sometimes contains pigments

It packages complex molecules for secretion of the cell

It is a small sac to enclose and transport complex molecules

They are involved in the synthesis and transport of lipids

It contains digestive enzymes
