MODE OF NUTRITION
▢ Autotrophs: Self nutrition → inorganic substances → organic food
▢ Heterotrophs:
❖ Saprophytes: Dead/decaying organic matter → nutrition
❖ Parasites:
Table 1: Parasitic Plants
Type | Subtype | Examples |
|---|---|---|
Root parasite | Total root parasite | Rafflesia, Balanophora, Orobanche |
Root parasite | Partial root parasite | Santalum, Thesium |
Stem parasite | Total stem parasite | Cuscuta / Dodder plant |
Stem parasite | Partial stem parasite | Loranthus, Viscum |
❖ Insectivorous Plants:
◉ Examples:
- •Nepenthes / Pitcher plant
- •Utricularia / Bladderwort
- •Drosera / Sundew plant
◉ Dischidia vs Nepenthes:

Feature | Dischidia | Nepenthes |
|---|---|---|
Lid | Absent | Present |
Nutrition | Non-insectivorous | Insectivorous |
Pitcher Function | Water storage | Insect trapping |
