6. What is the role of national gardens in conserving biodiversity – discuss

Aesthetic value touristspots

Wide range of species knowledge about bio diversity and provide material for Research

Can integrate diverse fields such as Anatomy Phyto Chemistry Physiology, Ecology etc

They are conservative centres especially for rare endangered species

Provide annual list of species & free distribution of seeds

Various attractions such as Arsboreum, Germplasm collection, Bambusetum, Insectivorous plants, The Great Banyan tree are major attractions available in National gardens in India, such as Lucknow, Trivandrum, Yercard, Kolkata respectively.

8. How does molecular markers work to unlock the evolutionary history of organisms?

Molecular markers, helps in establishing the phylogentic relationship of different plant groups at DNA Level.

This DNA cloning and sequencing methods help to unlock that treasure chest of information on evolutionary history of organisms different molecular markers, like allogymes, Mitrochondrial DNA, Microsatellites PFLP, RAPD, AFLPs SNP Micro chips, Arrays etc are used as molecular markers in thus help in understanding the evolutionary patterns of biodiversity are investigated.

10. How will you distinguish Solanaceae members from Liliaceae members?

Solanaceae (Dicot) Morphology

• Bulbous stem / rhizome / corm absent but stem tuber present

• eg. Solatium tuberosum

• Radical leaves Cariscup Absent from roots

• Leaves alternate & exstipulate

• Flowers – Pentamerous

• Calyx - Persistent -Solanum melongena

• Corolla of various shapes present

• Stamens - 5 - Epipetalous

• Carpels  

| Ovary superior

| bicarpellary, bilocular

Carpels oblipuely placed bicarpellary later become tetra carpellary due to the formation of false septa

• Fruits - Berry / capsule

• Anatomy:

Bi-collateral Vascular Bundles occur

Cambium present

Secondary growth present

Liliaceae (Monocot) Morphology

• Bulbous Stem - Lilium

Rhizome - Polygonatum

Corm Occur - Colchicum

• Radical leaves present eg. Lilium

• Slipules absent exstipulate fleshy and hollow

• Flowers - Trimerous

• Calyx, Corolla - Absent

• Perranth is only present

• Stamens - 6 - In a whorls of three each apostamenous

• Ovary superior tricarpellary trilocular

• Fruits - Loculierdal capsula

• Anatomy:

Conjoint collateral Vascular bundles

Cambium absent

No secondary growth
