Question

Write the name and function of the plastids found in following parts
of the plant .
a) green leaves
b) flowers
c) roots and stems

Answer 1

Answer:

Chromoplasts are plastids, which are involved in different coloured pigment synthesis and their storage. It is responsible for giving different colours to the flowers, fruits. 

The chloroplast is a type of plastid, which produces green coloured pigment. The chloroplast is involved in carrying out photosynthesis. It gives a green colour to leaves. 

Leucoplasts are one the type of plastid, which is non-pigmented. They are involved in storage functions. Such, colourless plastid is present in underground roots, stems. Thus, the correct answer is option c

Answer 2

Explanation:

The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a membrane-bound organelle[1] found in the cells of plants, algae, and some other eukaryotic organisms. They are considered endosymbiotic Cyanobacteria, related to the Gloeomargarita.[2] The event to permanent endosymbiosis probably occurred with a cyanobiont.[3] Plastids were discovered and named by Ernst Haeckel, but A. F. W. Schimper was the first to provide a clear definition. Plastids are the site of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color. They have a common evolutionary origin and possess a double-stranded DNA molecule that is circular, like that of the circular chromosome of prokaryotic cells
