Hint: The aquatic ecosystem contains a diverse array of living organisms and provides habitat for many species of aquatic plants, algae, and fungi. Plants and some types of green algae are autotrophic, meaning they produce their own food through photosynthesis. In contrast, fungi and some algae classes are heterotrophic. Seaweeds, such as Porphyra (a red algae used in Japanese sushi), are commonly consumed, though Porphyra belongs to the kingdom Protista.
Complete answer:
- Plants like lotus, water spinach, watercress, taro, and water chestnut thrive in water and have edible parts that are widely used in cooking.
- Nelumbo nucifera, commonly known as the Indian lotus, is an aquatic plant native to the Indian subcontinent but now also found in South Asia.
- It grows in marshy ponds with depths of about 2.5 to 3 meters and can extend up to 8 feet into the water.
- Its sturdy stem and flat, circular leaves float on the water’s surface, providing a base for the flower’s whorl.
- Lotus is cultivated for its edible parts, including seeds, roots, rhizomes, buds, leaves, stems, and flowers.
- Lotus seeds are highly nutritious and often used in rice dishes, soups, as ‘makhana’ (popped seeds), and in fermented dairy products.
- The rhizomes resemble raw potatoes, are sliced, and pickled for storage.
- Tender stems are sliced into small pieces and incorporated into salads and soups.
- The leaves can hold water and are sometimes used to wrap cooked rice.
- Dried lotus flower petals are powdered and used to make tea.
- Every part of Nelumbo nucifera is edible, and it is widely cultivated for culinary use.
Note:
- Lotus is symbolically significant and serves as India’s national flower; it is also considered sacred.
- Although the lotus can be eaten raw, caution is advised as it carries some health risks.
- Lotus seeds are susceptible to fungal contamination, so they are typically freeze-dried or sun-dried before consumption.
- Stems and rhizomes should be thoroughly cooked, as they may carry parasites.
