Question

Mention the functions of plastids pl s guve right answer
​

Answer 1

Plastids are double membrane-bound organelles found inside plants and some algae, which are primarily responsible for activities related to making and storing food. In plants, plastids may differentiate into several forms, depending upon which function they play in the cell. Undifferentiated plastids (proplastids) may develop into any of the following variants:

1. Chloroplasts: These plastids are green due to the presence of chlorophyll pigment, and hence are responsible for photosynthesis.
2. Chromoplasts: These are coloured plastids containing pigments other than chlorophyll, are found in fruits, flowers, roots, and stressed and aging leaves, and are responsible for their distinctive colors.
3. Leucoplasts: These are colourless non-pigmented plastids found in the non-photosynthetic parts of the plant, such as the roots, and may differentiate into more specialized plastids like-
4. Amyloplasts: used for storage of starch and gravity detection (geotropism).
5. Elaioplasts: used for fat storage.
6. Proteinoplasts: used for protein storage and modification.
7. Tannosomes: responsible for synthesizing and producing tannins and polyphenols.
