Question

Are the different types of plastids interchangeable? If yes, give examples where they are getting converted from one type to another.

Answer 1

Yes, the different types of plastids are interchangeable. This interchange takes place according to the stage of development.

For example; 

1. Flowers are modified shoot which means initially it is green in colour but later have different colours, this is due to the conversion of chloroplast into chromoplast.
2. Many fruits are green due to the presence of chloroplast when they are raw but after ripening many of them change their colour because chloroplast changes to chromoplast.

The cell is the smallest, the most essential and most complex of all living beings. The basic unit of living organisms is called a cell. Every cell is a building block for the formation of other cells. These cells are called organelles. All the organelles in a cell are found together. The smallest unit within the organelle is called a unit. The smallest organelle in the cell is called the mitochondrion. The structure of the cell is also called cell architecture. The cell architecture represents the organization of cells and helps to maintain their function. The cellular architecture depends on the type of cell and the species of the cell.
