Which is a parasitic plant?
Correct answer: A. cuscuta
- A. cuscuta
- B. rose
- C. ferns
- D. mosses
Explanation
Cuscuta, or dodder, is a parasitic plant that obtains water and nutrients from a host through specialized haustoria and has greatly reduced photosynthesis. Rose is an ordinary autotrophic plant, while ferns and mosses are also generally photosynthetic. Students may choose mosses because they lack vascular tissue, but lack of vascular tissue does not make a plant parasitic.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
