Q20. Which of the following plants does not show clear-cut vegetative, reproductive and senescent phase?

1. Perennial plants


Annuals complete their life cycle in one year while biennials complete in two years. Hence, vegetative, reproductive and senescent phases are clearly visible. Example : Wheat, Rice, cabbage.

Perenials are the plants which grow for more than two years.Since they grow for a longer time and does not die out after flowering, the demarcation of three phases is not clear and it is very difficult to identify these phases.
