Question

Which plants have a trap, which looks and shows like a flower to insects?
A) Dorsera
B) Balsam
C) Lotus
D) Venus Fly trap

Answer 1

Hint: The kingdom plants are divided into; pteridophytes, bryophytes, gymnosperm, and angiosperm. The basic criteria of classification of plants is the presence of vascular and non-vascular. As we all know that the plants are autotrophic in nature, but some of the modified plants are carnivores in nature as they trap insects for feeding.

Complete answer:
To solve this question, we have to know about carnivorous plants. The carnivorous plants tap, kill, and digest the insects. The carnivorous plants are divided into; passive trap and active trap. Such plants have digestive enzymes produced by them and bacterial decay within the trap. The passive trap is the pitfall trap of the pitcher plants, including Darlingtonia, Nepenthes of the Nepenthaceae, and Sarracenia of the Sarraceniaceae where an insect falls inside the vase-like modification of the leaf. The plant prevents the insect from crawling down as they have hairs on the slippery walls and the insect finally drowns in the bottom of the pool of digestive enzyme.
Now, the venus flytrap is the carnivores' flowering plants. The trap is made of two hinged lobes at the leaf end, on the inner surfaces of the lobes have trichomes that are hair-like projections cause the lobes of the snap get shut when the prey comes in contact with the plants. Such movement is termed as thigmonasty that is a nondirectional plant that shows response on being touched. The trap of the plant only gets shut when the trichome is touched many times to prevent the wastage of the energy if the prey is not there. The hinged traps are edged with bristles that get locked when the plant ensures the prey is not able to squirm out.

Thus, the correct option is ‘D’. Venus Flytrap.

Note: The Drosera plants have the twitchy tentacles that involve in the catapulting of the prey inside the sticky traps of the plants. The sticky tentacles then slowly bend to move the prey inside the leaves that are spoon-shaped inside there the prey slowly get digested.
