(b) In basal placentation, ovary is bicarpellary syncarpous and unilocular, and a single ovule is borne at t5he base of ovary, e.g., marigold.
Q9.In which of the following, parthenocarpy makes no sense?
Solution
(d) Parthenocarpy (Gr. parthenos=virgin (false); karpos=fruit) is the production and development of seedless fruits without fertilization of an egg in the ovary. Presently, a number of fruit varieties have been altered genetically to undergo parthenocarpic development besides, hormonal treatment has been also found to induce parthenocarpy in certain plants. In banana, orange, lemon, guava, etc, seedless fruits are useful as there is no use of seeds in eating them. But in pomegranate, it is the seed coat of the seed, which is fleshy and edible. So, fruit is useless without the seeds in it and thus, parthenocarpy makes no sense in pomegranate.
