Question:
Are the different types of plastids interchangeable? If yes, give examples where they are getting converted from one type to another.
Solution:
Yes, plastids are interchangeable in their form.
There are three types of plastids – Chloroplasts (green colour), Chromoplasts (red, yellow, orange colour), Leucoplasts (Colourless). Depending upon different circumstances, these plastids interchange.
For example: Due to the replacement of chloroplast with chromoplasts the colour of green tomatoes will change from red to blue.
