FAQs on Parasitic Plants Video Lecture - Science Class 7

1. What are parasitic plants?
Ans. Parasitic plants are a unique group of plants that obtain nutrients from other living plants. They attach themselves to the host plant and derive water, sugars, and minerals from it, often causing harm or even death to the host plant in the process.
2. How do parasitic plants attach themselves to the host plant?
Ans. Parasitic plants use various mechanisms to attach themselves to the host plant. Some species have specialized structures called haustoria that penetrate the host plant's tissues to access nutrients. Others may wrap around the host plant or use adhesive secretions to cling onto it.
3. Do parasitic plants have chlorophyll?
Ans. Not all parasitic plants have chlorophyll. While some parasitic plants retain their ability to photosynthesize and produce their own food, others have lost their chlorophyll and rely solely on the host plant for their nutritional needs.
4. What are the ecological impacts of parasitic plants?
Ans. Parasitic plants can have both positive and negative ecological impacts. On one hand, they can help regulate the growth of certain plant populations and contribute to biodiversity. On the other hand, they can weaken or kill host plants, leading to reduced productivity and diversity in affected ecosystems.
5. How can parasitic plants be controlled or managed?
Ans. Controlling parasitic plants can be challenging, but several methods can be employed. These include physically removing the parasitic plants, using herbicides specifically designed for parasitic plants, promoting the growth of desirable host plants, and implementing proper land management practices to prevent the spread of parasitic plants.
