What are Plastids?

• Plastic term was coined by Ernest Haeckel in 1866.
• Plastids are double membrane bound organelle found in plants, algae and photosynthetic microorganisms.
• They bear some specific colours to the plants.

Types of Plastids

1️⃣ Leucoplasts:

• Leucoplasts are colourless plastids found in non-green and underground plant cells.
• Eg: Tuber, Roots, nuts, seeds, bulbs, endosperms.

2️⃣Chloroplasts:

• Chloroplast organelles that contain chlorophyll and cartenoid pigments which are responsible for trapping light energy.
• Have a role in photosynthesis.
• Inside chloroplast colourless ground matrix called stroma and the membrane system called Grana.
• Chlorophyll are present in Thylakoid membrane.
• Number chloroplast in per mysophyll is 52-200.
• Each Chloroplasts contain about 20-100 granum.
• Thylakoid are arranged in stack like the pile of coins called Grana.

3️⃣Chromoplast:

• A chromoplast is a pigmented plastid found in fruits, flowers, roots of carrot and some leaves of Senescing.
• They are colourful pigments- Carotenoids.
• Red colour chillies and red tomatoes is due to the red pigment (Lycopene) of Chromoplast.
