Which botanical species operates as a parasite?

Select your answer for: Which botanical species operates as a parasite?
Show answer

Answer: A. cuscuta

Explanation

Cuscuta species are parasitic plants that completely lack functional chlorophyll pigments for photosynthesis. They derive all necessary organic nutrients and water directly from a living host plant. Specialized root-like structures called haustoria penetrate host vascular tissues to absorb vital sustenance. Dodder plants twine around host stems using bright orange or yellow specialized threadlike vegetative vines. Parasitic plants reduce host vigor and can severely impact agricultural crop yields during infestations. Botanical classification groups Cuscuta within the morning glory family despite its parasitic lifestyle.

Farmers implement strict weed control measures to eradicate Cuscuta infestations from commercial crop fields. Studying parasitic plants provides insights into the evolutionary loss of photosynthetic metabolic pathways. Ecological interactions between parasites and hosts help regulate plant community diversity in natural habitats. Roses are autotrophic shrubs that manufacture their own food through standard green plant photosynthesis. Ferns are vascular non-flowering plants that produce their own energy via independent frond photosynthesis. Mosses are primitive non-vascular bryophytes that generate organic nutrients through autotrophic metabolic pathways.
