Question

Which of the following is a carnivorous plant?
(a)Sundew
(b)Lichen
(c)Fern
(d)Mould

Answer 1

The plants are commonly known as Drosera, which derives their nutrients from trapping and consuming various animals and protozoans or typically insects for their nutrition. They trap and capture their prey.

Complete answer:
Sundew is a carnivorous plant that is commonly known as Drosera. It is the largest genus of carnivorous plants which constitutes 194 species. bacon digest and capture insects using stalked mucilaginous glands that cover their leaf surfaces. They vary in size and provide a supplement to the soil mineral nutrition in which the plant grows. They are perennial and form scrambling stems that reach much longer lengths up to 3 meters. They are characterized by the glandular tentacles that are present on the top with the sticky secretions that cover their laminae. The prey gets trapped by the mucilage which is sticky and prevents their escape and progress. The insect gets succumbed to death as the mucilage encloses it and clogs its spiracles through exhaustion.

Additional Information: Lichen: It is an organism that arises from algae or cyanobacteria and constitutes filaments of multiple fungi species in a mutualistic relationship with them. They vary in different forms and sizes in some plants but are not plants. They occur from the sea level to the high alpine elevations and can grow almost on any surface. They are not capable of reproducing sexually and engage with other microorganisms which evolved as a more complex composite organism.
Fern: It is a group of vascular plants that reproduce with sports and do not have seeds and flowers. This constitutes specialized tissue that conducts water and nutrients in which the sporophyte is the dominant phase in their life cycle. Some are used as food which includes various species. They are resistant to phytophagous insects. A gene which expresses the protein in an edible fern is transferred to cotton plants to become resistant to whitefly infestations.
Mould: It is a fungus that grows in the form of multicellular filaments known as hyphae and adopts a single cell growth Habitat known as yeasts. They are ubiquitous and our common component of household and workplace dust.

So, the correct answer is 'Sundew'.

Note: Eating meat by carnivorous plants help them in living in tough places. Some of the species consist of pit shaped traps to attract the insects. 6% of the Earth's surface is covered by lichens which constitute 20,000 known species. The first Fossil record appeared was of ferns that were 360 million years ago.
