Question

A) Describe the mechanism of pollination in salvia.
B) Is cheetah extinct or endangered in India, Why?

Answer 1

Hint: The defining point of the genus Salvia is the unusual pollination mechanism when a pollinator probes a small stage of flower for nectar. Cheetah was announced extinct from India and considered the only large mammal that has gone extinct since the country’s independence.

Complete Answer:
A) Mechanism of pollination in Salvia is a genus of plants that belongs to the family Lamiaceae.
 - They are characterized by a staminal level of mechanism which aids in the transfer of pollen grains in them.
- Salvia is an excellent example of insect pollination which happens by turn pipe mechanism. In their type of plants, the monothetic stamens are modified into levels.
- The thin ligament between the connective and the filament forms a joint that is then divided into upper and lower arms.
- A pollinator searching for a hector must push back the lower arms to allow the pollen sacs at the end of the upper lever arms to be passed onto the pollinator’s head or back. Saliva is classified by their pollination mechanisms based on floral traits.
- Staminal structure, and pollen deposition occur on the body of bees.

B) The Asiatic cheetah in India has become extinct due to some unnatural causes. Cheetah is considered the only large mammal; it has vanished because of their habits.
- There are many reasons for population decline in open habitats but all of them stem from one cause, neglect such neglect began under British rule, who saw open habitats as formerly closed-canopy forests degraded by human abuse of the land. So they responded by attempting to right a perceived wrong, banning grazing.
- Preventing controlled fires and promoting afforestation. But Cheetah was last seen only until then, the neglect continued.

Note: Today, open habitats of India are erratically enlarged, because maximum animal reservation centers or zoos are openly protected.
Example: Kruger national park, South africa.
