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.
$3$. Leucoplast	Colourless plastids; primarily store starch, oils, and protein granules.
