Drosera : Amazing insect eating plant
This plant is Drosera indica, one of the carnivorous plants. Drosera, from the Greek, droseros (droseros), "dewy, watery" and indica is derived from India. Plant is carnivorous if it attracts, captures, and kills animal life forms. It must also digest and absorb the nutrients from the prey to qualify as a carnivo
rous plant. There are many noncarnivorous plants that do some (but not all) of these things. For example, flowers attract pollinators (such as insects, birds, and other creatures, even humans!); some plants such as orchids and water lilies temporarily trap insect pollinators to ensure pollen transfer. All plants absorb nutrients either through their roots or leaves. However, even though these plants do some of the things that carnivorous plants do, they do not fulfill all of the criteria necessary to qualify as a carnivorous plant. Only plants which attract, capture, kill, digest, an
d absorb prey are truly carnivorous.
Carnivorous plants are just like other plants, except they have a toolbox of abilities that, altogether, allow the plant to be carnivorous. Other plants have a few of these tools, but not all of them. The main tools are the abilities to attract insects, capture them, kill them, digest them, and absorb the resulting nutrients. Noncarnivorous plants have flowers to attract and even capture insects, toxic compounds to kill insects feeding on them, molecules that have digestive properties, and structures like roots to absorb the nutrients. Carnivorous plants just comb
ine these features in an interesting way.
This tiny plant is naturally found along muddy soil in its specific habitat. Forms vary mostly in plant and flower color. Plants can be green or red, and flowers may be either white, pink, or orange. Drosera indica is an annual which means under normal circumstances within one growing season it will grow quickly, bloom, set seed and die. In nature the seeds sprout with the onset of the rainy season. It requires very warm and bright conditions to do well. The plants bloom and then die in the fall as the ground dries out. After an insect has been caught, the glandular heads secrete a digestive fluid which dissolves all that can be absorbed from the insect. These work on reducing the fleshy internal part of the insect into a nutrient soup which is subsequently absorbed by the plant. It has been noted that secretion does not take place when inorganic substances are imprisoned. Once digestion and absorption is complete, leaving to dried exoskeleton to be washed away by rainfall, or simply left as a warning to other insects.
