Parasite
Cuscuta, commonly known as dodder, is a parasitic plant that belongs to the family Convolvulaceae. It is a perfect example of a parasitic plant.

Characteristics of Cuscuta
- Cuscuta lacks chlorophyll, which means it cannot photosynthesize and produce its food.
- It depends entirely on other plants for its nutrients.
- It wraps itself around the host plant and penetrates its vascular system to extract water and nutrients.

Parasitic Nature
- Cuscuta is considered a parasite because it derives its sustenance from the host plant without providing any benefit in return.
- It weakens the host plant by taking away essential nutrients, which can eventually lead to the death of the host plant.

Impact on Ecosystem
- The presence of Cuscuta in an ecosystem can disrupt the balance by affecting the growth and survival of other plant species.
- It can reduce the overall biodiversity of the area where it infests.

Control Measures
- To control the spread of Cuscuta, it is essential to remove the affected plants carefully.
- Herbicides can also be used to manage the growth of Cuscuta in agricultural areas.
In conclusion, Cuscuta serves as a prime example of a parasitic plant that relies on other organisms for its survival, highlighting the diverse interactions present in the natural world.
