Select the incorrect statement from the following :

a- Reproduction enables the continuity of the species, generation after generation.

b- Strobilanthus kunthiana (neelakuranji), flowers once in 20 years.

c- Bamboo species flower only once in their life time, generally after 50-100 years.

d- In both plants and animals, hormones are not responsible for the transitions between the three phases.

Choose the correct answer from the given options.

b and d

The correct answer is Option (4) – b and d

Reproduction enables the continuity of the species, generation after generation.

Plants –the annual and biennial types, show clear cut vegetative, reproductive and senescent phases, but in the perennial species it is very difficult to clearly define these phases. A few plants exhibit unusual flowering phenomenon; some of them such as bamboo species flower only once in their life time, generally after 50-100 years, produce large number of fruits and die. Another plant, Strobilanthus kunthiana (neelakuranji), flowers once in 12 years.

In both plants and animals, hormones are responsible for the transitions between the three phases. Interaction between hormones and certain environmental factors regulate the reproductive processes and the associated behavioural expressions of organisms
