Plastids are membrane-bound organelles found in plant, algae, and some eukaryotic cells. Plastids contain their own DNA and ribosomes and are the site of important chemical compound manufacture and storage. There are three main types of plastids: chloroplasts, which contain chlorophyll and conduct photosynthesis; chromoplasts, which impart color to flowers and fruits; and leucoplasts, which store starch, oils, and proteins.

2. ● Plastids is a membrane bound organelle found in the cells of plants,
algae, and some other Eukaryotic organisms.
● Plastids was discovered by 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 cell of autotrophic eukaryotes
INTRODUCTION TO PLASTIDS

3. 1. Plastids Occur in most plant cells.
2. Absent in animal cells.
3. Plastids have own DNA and Ribosomes
Cell organelle = Plastids

4. Chromoplasts (coloured plastids) -
● They are found in fruits, flowers, roots, and senescent leaves. The colour of these plant
organs is associated with the presence of pigments, apart from chlorophyll
● Chromoplasts impart colour to flowers and fruits.
Leucoplasts (white and colourless plastids)
● Primary organelles
● Store starch, oils and protein granules
PLASTIDS ARE DIVIDED INTO 3 PARTS

5. LEUCOPLASTS POTATO

6. Chloroplasts
● Chloroplasts are organelles found in plant cells
● Also in eukaryotic algae that conduct photosynthesis.
● The kitchen of the cell
● Helps in photosynthesis
● Contain Chlorophyll pigment

Chromoplasts impart colour to flowers and fruits.
Leucoplasts store food.
