Carnivorous Plants Insects To Obtain Nitrogen Jawaban

You may have seen big hungry plants eating humans in a dark forest in lots of Sci-fi movies. Though Carnivorous plants do exist but they are certainly not “Man-eaters”. There are some predatory species of the plants that can trap, kill, eat and digest animals and they are known as the carnivorous plants. Here carnivorous does not mean that these plants are capable of eating big sized rabbits or rodents, but the term refers to small amphibians, insects and arthropods. The first treatise about these plants was written by Charles Darwin in the year 1875 by the name of, “Insectivorous Plants”.

Why don’t these plants live like normal plants? Why do they eat insects and other animals? The reason is that these plants exist in rocky areas or bogs, where the soil quality is very poor and lacks essential nutrients such as nitrogen. To fulfill their energy requirements the plants consume insects and other small animals. These plants have evolved six times independently in 5 different orders of flower bearing plants and today they are represented by several genera. There are over 630 species of these plants, and also there are additional 300 species that have some of the characteristics of Carnivorous plants.

Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow.

The worms excrete most of their excess nitrogen as ammonia, which is why they are the primary prey of most carnivorous fungi. Which is why they are the primary prey of most carnivorous fungi. 2 Insect-Eating Pitcher Plants.

Carnivorous plants have various trapping strategies. Some of these plants have specially designed brightly colored leaves that are used to trick and trap unsuspecting animals and insects. Some have a sweet scent that helps attract animals towards them while others have sticky slippery parts that makes it difficult for the prey to escape. There are two major categories of the Carnivorous Plants, one with the active traps and other with the passive traps.

The active traps are those with spiny hinged leaves and tend to move really fast, where passive traps are plants having leaves shaped like a vase. Let’s have a look at some if these Carnivorous plants and their prey capturing techniques. Venus Fly Trap Venus Flytrap scientifically known as Dionaea muscipla is the most famous kind of Active Carnivorous plants. This astonishing little plant occupies a narrow strip of land, 100 miles long and 10miles wide in the coastal area of North Carolina. It is the relative of Sundew plant.

The insects are attracted to these plants for nectar found on its blade like leaves. As soon as an insect touches the tiny hair present inside the leaves the fringe of spiny hair found around the leaves snap shut trapping the prey inside. Then the leaves release some digestive enzymes and absorb essential nutrients. Sundew Plant These plant species belong to genus Drodera.

Sundew plants have hundreds of tentacles all over its leaves that produce a shiny sticky substance that is often confused with the dew, as sunlight like makes them glitter. The insects are tricked by these fake dew drops and get stuck to the leaves.

The poor prey is then enclosed within the tentacles and digestive enzymes start their work. In some cases, bugs reside on these plants; these bugs eat up the insects that get trapped and serve the plants with their waste products.
