Question

Insectivorous plant with rosette of spiny margined bilobed hinged and winged leaves for catching the prey is
A. Nepenthes
B. Drosera
C. Dionaea
D. Utricularia

Answer 1

Hint: These plants are insectivorous, which means they eat insects, and they get most of their nourishment from the insects they catch and devour. These plants thrive in humid environments with lots of sunshine and moisture. Insectivorous plants have names like Venus flytrap, pitcher plant, and cobra lily.

Complete answer:
The pitcher of most Nepenthes species consists of a leaf-like lid sparsely covered with trichomes, and a collar-like ribbed upper rim called the peristome, bearing nectaries, and a slippery zone covered with lunate cells and a thick epicuticular wax layer, and a digestive zone regularly covered with numerous digestive glands, and a pool of digestive fluid.
The tentacles of the Drosera plant trap insects. Their leaves have a lot of sticky hairs on them called tentacles. Insects arch over and tie tentacles as they come into touch with them. Proteolytic secretions from the leaf digest the trapped bug.
Dionaea muscipula (Venus flytrap) is a carnivorous plant. The plants' glands emit an enzyme to break down the prey and absorb the nutrients released after catching their prey, often insects, with a trapping structure made by their leaves. To capture insects, the lamina of the leaf is transformed into a pin-like protrusion.
Utricularia contains sensitive bristles or hairs in its bladder. When an insect comes into contact with these hairs, the door opens, allowing the insect and a little stream of water to enter the bladder.

So, option C is the right choice.

Note: Plants that are insectivorous get part of their nutrition from capturing and eating animals or protozoa. The value they get from their catch varies greatly; for some species, it may only account for a tiny portion of their nutritional intake, while for others, it may be an essential source of nutrients.
