Answer 1

hii mate here is the answer to your question

we all know, that the basic unit of a flower and leaf is cell but they are different in their appearances mainly due to the absence of the characteristic plastid in them . There are three types of plastids

chloroplastids, chromoplastids and leucoplastids. chloroplastids are the the duouble membraned cytoplasmic cell organelle containing pigment chloroplast which helps in photosynthesis and is present in green parts of the plant in the mesophyll of leaf whereas chromoplastid is responsible for imparting colour other than green to the parts of the plant example fruits, flowers etc.
