Which genus of carnivorous plants is known as the sundews, using sticky, moving tentacles to bind their prey?

Pick one

or
B: Drosera

Drosera, or sundews, make up one of the largest genera of carnivorous plants. Their leaves are covered in gland-tipped tentacles that secrete a sticky, dew-like substance. Once an insect is caught, the tentacles actively bend to bring more digestive glands into contact with the prey.

Pick one

or
A: By generating a rapid vacuum suction

Bladderworts are among the fastest-acting predators in the plant kingdom. They pump water out of their tiny bladders to create a vacuum. When a tiny organism touches the trigger hairs, the trap door swings open and sucks the prey inside in less than a millisecond!

What surprising mutual relationship does the pitcher plant Nepenthes lowii share with tree shrews?

Pick one

or
B: The shrews use the pitchers as toilets, providing nitrogen

In a fascinating ecological partnership, the mountain tree shrew licks a sweet, laxative nectar from the lid of Nepenthes lowii. While feeding, the shrew sits on the pitcher rim and defecates directly into the trap, providing the plant with essential nitrogen.

Pick one

or
B: Dry, rocky soils of the western Mediterranean

Commonly known as the dewy pine, Drosophyllum is a rare carnivorous plant native to dry, sandy, or rocky soils in Spain, Portugal, and Morocco. It is highly unusual because almost all other carnivorous plants thrive in wet, nitrogen-poor wetlands.

Pick one

A: Charles Darwin

Charles Darwin was utterly fascinated by these plants, especially sundews. He spent years studying how they react to touch and nitrogen-rich substances, eventually writing 'Insectivorous Plants'. He even wrote in a letter that he cared more about Drosera than the origin of all other species!
