Question:

In some plants where flowering occurs more than once what would you will call the inter flowering period:

(A) Juvenile 

(B) Mature 

(C) Senescent 

(D) Aging 

Answer: option (A) Juvenile

Explanation:

Option A : The plants which flower more than once, their inter - flowering period represents the juvenile phase. Although they pass the mature phase of flowering for the first time. But for flowering for the next time, they require further development. Therefore this is the correct option.

Option B: Mature phase of a plant is when it has the ability to flower and reproduce. In plants where flowering occurs more than once, the plant regresses back to the juvenile phase before it flowers again. Therefore this is an incorrect option. 

Option C: Senescent phase marks the end of the reproductive phase of the plant. Senescent phase signifies that after this phase the plant cannot reproduce. Therefore this is an incorrect option. 

Option D:Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. Chlorophyll degradation during leaf senescence reveals the carotenoids, such as anthocyanin and xanthophylls and is the cause of autumn leaf color in deciduous trees. Leaf senescence has the important function of recycling nutrients, mostly nitrogen, to growing and storage organs of the plant. Therefore this is an incorrect option. 

Hence, the correct answer is option (A) "Juvenile".
