Answer 1

(i) Parasitic Plant:

1. Cuscuta is a parasitic plant with a golden, slender, tubular stem.
2. The parasite is exemplified by Cuscuta.
3. It seeks refuge in a host cell. It is reliant on the sustenance of another organism.

1. The pitcher plant is a plant that may eat both autotrophically and heterotrophically.
2. Pitcher plants capture insects because they grow in low-nitrogen soils.
3. Photosynthesis is used by pitcher plants to create carbohydrates.
4. However, it captures and digests insects as a source of nitrogen.
