Question

What are leucoplasts? Name and describe their different types?

Answer 1

Leucoplasts are non pigmented organelles or part of organelle - Plastid.They are categorized into 3 types described as follows:-

• Leucoplasts are a kind of colorless storage organelle.
• Plastid (double membrane organelles) consists of Chloroplast and Leucoplast.
• Chloroplast consists of a pigment called Chlorophyll that helps in Photosynthesis.
• Leucoplasts majorly have storage functions.
• Three types of Leucoplasts are:-

1. Amyloplasts - storage and synthesis of starch, present in storage tissue and roots.
2. Elaioplasts - synthesis and storage of fatty acids, terpenes, and other lipids.

• Present mostly in leaves and Anthers.

    3. Aleuroplasts - help in the storage of proteins.

• They are also sites of enzyme activity involving particular proteins.

Answer 2

Answer:

Leucoplasts are colorless plastids with different specialized functions. They synthesize lipids and other materials and help in storing fats, proteins, amino acids, etc. They are of 4 types Proplastids, Amyloplasts, Proteinoplast, and Elaioplasts.

Explanation:

• Proplastids- They are plastids of young rapidly dividing cells. They develop into chloroplast when exposed to light.

• Amyloplasts- They are associated with the synthesis and storage of starch.

• Proteinoplast- They help in the storage of proteins that are required by the plant.

• Eliaoplasts- They are associated with the storage of fats and oils that are required by the plant.
