Answer 1

What Are Plastids?

Did you ever wonder how plants breathe, drink, eat, and grow? They carry out these functions just like us, yet in different ways. One category of specialized organelles that plants use in order to survive is plastids.

Plastids are double membrane-bound organelles found inside plants and some algae, which are primarily responsible for activities related to making and storing food. Many plastids are photosynthetic, but some are not.

Some of the most common plastids include:

Chloroplasts Chromoplasts Gerontoplastsand Leucoplas

Plastids are present in most of the plant cells and absent in animal cells. They are usually spherical in shape. These are double membrane bound organelles. They have it's own DNA amd ribosomes.


$\huge{Types\:of\:Plastids\::}$


1) Chloroplast :-

* Carry photosynthesis.

* Contain chlorophyll and carotenoid pigments.

* These are green pigments.

* Found mainly in leaves and green stem. They trap light for photosynthesis.


2) Chromoplast :-

* Carry non-photosynthesis.

* Contain fat soluble carotenoid pigments.

* They have red, orange or yellow pigments.

* Give colour to fruits, carrot, red peppy and flowers.


3) Leucoplast :-

* Carry non-photosynthesis.

* They have capacity to develop pigments when required.

* Colourless as they lack any pigments.

* Abundant in storage organs like roots, seeds and young leaves.

Ex :- Amyloplast stores starch, Elaioplasts stores store fats and oils. Aleuroplast store proteins.
