Brocchinia reducta is one of few carnivorous

Carnivorous plant

Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods. Carnivorous plants appear adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic...

B. reducta, like many other bromeliads, forms a water-storing cup with its tightly-overlapping leaves. The leaves surrounding the cup of B. reducta are coated with loose, waxy scales. These scales are highly reflective of ultraviolet

The scales, being loose, provide a poor foothold for insects landing on them. The unfortunate creatures slip into the water-filled cup and eventually drown.

It has been argued that B. reducta is not actually carnivorous in the sense of other such plants because the production of digestive enzyme

Enzymes are proteins that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates...

A phosphatase is an enzyme that removes a phosphate group from its substrate by hydrolysing phosphoric acid monoesters into a phosphate ion and a molecule with a free hydroxyl group . This action is directly opposite to that of phosphorylases and kinases, which attach phosphate groups to their...
