Kingdom Plantae includes all eukaryotic chlorophyll-containing organisms commonly called plants. A few members are partially heterotrophic such as the insectivorous plants or parasites. Bladderwort and Venus fly trap are examples of insectivorous plants and Cuscuta is a parasite. The plant cells have an eukaryotic structure with prominent chloroplasts and cell wall mainly made of cellulose. You will study the eukaryotic cell structure in detail in Chapter 8. Plantae includes algae, bryophytes, pteridophytes, gymnosperms and angiosperms.
Match the following organisms with their correct modes of nutrition : Column I (Organism) a) Bladderwort b) Venus fly trap c) Cuscuta d) Anabaena e) Euglena Column II (Mode of Nutrition) 1. Heterotrophic 2. Parasitic 3. Autotrophic
Correct answer: C — a–1,3; b–1,3; c–2; d–3; e–1,3
Bladderwort (a–1,3): insectivorous → mainly autotrophic (photosynthetic) but also heterotrophic (captures insects for nitrogen). Venus fly trap (b–1,3): same as Bladderwort → autotrophic + heterotrophic supplement. Cuscuta (c–2): obligate parasite, lacks chlorophyll → purely parasitic. Anabaena (d–3): cyanobacterium → photosynthetic autotroph with nitrogen fixation. Euglena (e–1,3): mixotrophic → autotrophic in sunlight, heterotrophic in darkness.
