Solution
The correct option is D Drosera
The correct option is D.
The explanation for the correct option:
- Drosera, also known as Sundew, is a perennial herbaceous plant that belongs to the Droseraceae family and is among the most prominent families of insectivorous plants.
- Members of this family use stalked mucilaginous glands on their leaf surface to feed, trap, or capture insects and digest them.
The explanation for the incorrect options:
Option A:
- Balanophora It's a parasitic plant genus in the Balanophoraceae family. It's a total root parasite, which means the parasitic plants' expansion, survival, and reproduction are all dependent on the host plant.
- These are primarily found in Asia's tropical and temperate zones. The odour is produced by several species, which may attract pollinators to the plant.
Option B:
- Rafflesia is among the most giant parasitic flowers in the Rafflesiaceae family.
- This organism has a large flower, buds that grow from the ground or straight from the host plant's lower steam, and no leaves, stems, or roots.
- It is a complete root parasite that grows and survives solely on the nutrients provided by its host plant. Rafflesia emits a foul odour that attracts insects that aid in plant pollination.
Option C:
- Orobanche Root parasites of the genus Orobanche, or broom-rape, in the family Orobanchaceae, shape holoparasite or obligate parasites, parasites that cannot complete their life without exploiting their host.
- These plants have yellow, white, or blue snapdragon-like flowers and lack chlorophyll. Therefore, they rely entirely on some other plants for nutrients due to their lack of chlorophyll.
Final answer: Drosera is an insectivorous plant.
