Question

Consider the following statements. (a) In racemose inflorescence the flowers are borne in a basipetal order. (b) Epigynous flowers are seen in rose plants.
(c) In Brinjal, the ovary is superior.
Of these statements
(A) a and b are true but c is false
(B) a and c are true but b is false
(C) a and b are false but c is true
(D) b and c are true but a is false
(E) a and c are false but b is true

Answer 1

Hint: The racemose is the type of inflorescence in which the youngest flower is borne near to the apex and the oldest flower is borne near or at the base of the inflorescence. Whereas in rose the ovary which is seen is in a superior position. The hypogynous flowers are seen in the family Solanaceae.

Complete step by step answer:
In racemose inflorescence, the flowers are borne in an acropetal order. In rose plants and brinjal, the ovary is superior as the flowers are hypogynous. The Basipetal order is seen in the cymose inflorescence. The cymose inflorescence is found in the hibiscus flower.
 Epigynous flowers are present in cucumber plants. In epigynous flowers, the sepals, petals, and stamens seem to arise from the top of the ovary. In such flowers, the ovary is often said to be inferior and the other floral whorls are superior.
Ovaries can also be classified based on placentation. Placentation means the arrangement of the ovules inside the ovaries. It is classified based on the number of compartments and placenta and the arrangement of ovules accordingly and the axes of ovule attachment.
Ovaries can be superior, marginal, parietal, axial, free-central, or basal in the arrangement.
So, the correct answer is ‘(C) a and b are false but c is true’.

Note: In racemose types of inflorescence the main axis grows continuously and flowers are present laterally on the floral axis. Flowers are present in an acropetal manner. In the cymose inflorescence, the main axis does not grow continuously, a flower is present terminally on the main axis. The flowers are borne in a basipetal order. The main axis has limited growth.
