  2. Mangrove plants

  3. Grass

  4. Fir forests
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sunderbans contain mainly mangrove plants. These are the mangrove area in the region of bay of Bengal. They have a thick canopy. The name is derived from the Sundari, the local name of the mangrove species Heritiera fomes. 

Thus, the correct answer is 'Mangrove plants.'

Multiple choice vernalisation plant growth growth and development plant growth and development biology

Vernalization is subjected to plants growing in 

  1. Tropical areas

  2. Sub tropical

  3. Temperate areas

  4. Hot areas/Arctic region
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Vernalization refers to the phenomenon of inducing flowering in plants by subjecting them to prolonged cold temperatures. After vernalization, plants acquire the ability to flower. Vernalization is subjected to plants growing in Temperate(temperature in these regions is moderate) areas.
So, the correct answer is 'Temperate areas'.
Multiple choice biology main natural resources classification of threatened species red data book methods of conservation

Red data book is for enlisting

  1. Endemic species

  2. Decorative plants

  3. Exotic species

  4. Plants on verge of extinction
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

'Red Data Book is also known as 'Red Book' or 'Russian Red Data Book'. It is a state document established for documenting rare and endangered species of animals, plants and fungi, as well as some local subspecies that exist within the territory of the 'Russian Federation' and its continental shelf and marine economic zone. The book has been adopted by Russia and all CIS states to enact a common agreement on rare and endangered species protection. The book provides a central information source in organizing studies and monitoring programs on rare and endangered species and their habitats. It is regularly consulted when developing and implementing special measures for the protection and rehabilitation of such species.

Multiple choice biology main natural resources classification of threatened species red data book methods of conservation

If a certain plant species is not found in its wild localities even after repeated search, then it would be listed in which category in the "Red Data Book"?

  1. Extinct

  2. Endangered

  3. Vulnerable

  4. Rare
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

There are nine categories present in the 'IUCN Red List' system: extinct, extinct in the wild, critically endangered, endangered, vulnerable, near threatened, least concern, data deficient and not evaluated. 

Classification into these categories occurs through a set of quantitative criteria that are based on biological factors that include the rate of decline, population size, the area of geographic distribution, and degree of population and distribution fragmentation. 
A species is listed as extinct in the wild when it is known only to survive in cultivation, captivity or as a naturalized population outside the previous range. A species is presumed extinct in the wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual.
