What are plastids? Give the various types of plastids present in plants along with their functions.
(N/A) Plastids are double-membrane-bound organelles present only in plant cells. Like mitochondria, they contain their own $DNA$ and ribosomes, allowing them to synthesize some of their own proteins.
| Type of Plastid | Function |
| $1$. Chloroplast | Contains chlorophyll; involved in photosynthesis to produce food. |
| $2$. Chromoplast | Contains pigments other than green; imparts attractive colours to flowers and fruits. |
