Question

Which of the following is the WRONG match between the plant and its character for adaptation of cross pollination?
A) Zosters - Bright colored flowers with nectar
B) Bougainvillea - Petaloid bracts
C) Passion Flower – Corona
D) Adenosine - Copious nectar.

Answer 1

Plants adaptation for cross-pollination have various mechanisms to prevent self-pollination. The reproductive organs are arranged in such a way that it is impossible to fertilize themselves, or the stamens and carpels may mature at different times. Plants suitable for self-fertilization usually have similar stamens and carpel lengths.

Complete answer:
Zostera is a water submerged plant. In this case, cross-pollination occurs with the help of water. Petals al film is a modified leaf, surrounded by bougainvillea flowers. These brightly colored pieces, thus making bougainvillea colorful, attractive to pollinators. Passionflower is less attractive, so the corona is often used to enhance beauty and attract bats to cross-pollinate. Adansonia flowers secrete a lot of sugary nectar from nectaries and a lot of pollen. These flowers are pollinated by bats.

Thus, the correct answer is option ‘A’.

Note: Passionflower, also known as Passiflora, is a genus of approximately 550 flowering plants, a genus of the Passiflora family. Most of them are vines with tendrils, and some are shrubs or trees. They can be woody or herbaceous. Bougainvillea is a genus of thorny ornamental vines, shrubs or trees. It is native to eastern South America, from Brazil, west to Peru, and south to southern Argentina. Different authors accept 4 to 18 species in this genus.
