Explanation
The insectivorous plant is Nepenthes.
Nepenthes, commonly known as the "tropical pitcher plant" or "monkey cups," is a genus of carnivorous plants that trap and digest insects and other small prey. The plant has modified leaves that form into elongated, tubular-shaped "pitchers," which are filled with a liquid that attracts and traps insects. The insects are then digested by enzymes produced by the plant.
On the other hand, Cycas is a gymnosperm plant that produces seeds without flowers or fruit.
Sunflower is an angiosperm plant that produces seeds inside a fruit called achene.
Cuscuta, commonly known as "dodder," is a parasitic plant that attaches itself to the stems of other plants and extracts nutrients from them.
