Question

Root pocket occurs in?
A. Maize
B. Pandanus
C. Banyan
D. Water hyacinth

Answer 1

Hint:
Root pockets are basically root caps but they have lost their utility due to their non-use. This is due to the fact that the roots of the plants which hang freely in water have no friction or resistance from the soil particles to overcome. So, the root pockets are the vestigial (non-functional) root caps. These can not be regenerated once they are removed. They are found only in the floating aquatic plants such as Pistia, water hyacinth and Trapa.

Complete answer:
Option (A) is Maize
Maize, also termed as corn, is a cereal grain which was first domesticated by the indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of this plant produces the pollen inflorescences and separate ovuliferous inflorescence called as ears that yield kernels or seeds, which are often fruits.

Option (B) is Pandanus
 A genus of monocots with some 750 accepted species is called pandanus. Native to the Old World tropics and subtropics, they are palm-like, dioecious trees and shrubs. Some other names of this include pandan, screw palm, and screw pine. They are classified in the order Pandanales and the family is Pandanaceae.

Option (C) is Banyan
A bayan is also spelled as "banian". It is a fig which begins its life as an epiphyte. It means a plant that grows on another plant when its seed germinates in a crack or crevice of a host tree or edifice.

Option (D) is Water hyacinth
Common water hyacinth is commonly known as Pontederia crassipes. It is an aquatic plant which is native to the Amazon basin and is a highly problematic invasive species outside its native range.

So, the correct answer is an option D- 'Water hyacinth'.
