Also, how does dodder find a host?
Once a host is located, dodder begins to wind around the stem. Its diminished root system completely dies off. It then uses specialized cells called haustoria to tap into the host's vascular tissue. This is not so good for the host as it can severely weaken it, leaving it susceptible to viruses and other diseases.
Beside above, what happens to the dodder plant if it does not find a host plant? Dodder continues to grow until its host can no longer provide enough food for both itself and its parasite. At that point, the host plant will die. If the Dodder is not connected to any other host plants, it will die, too.
Consequently, how does dodder get its food?
The dodder contains no chlorophyll and instead absorbs food through haustoria; these are rootlike organs that penetrate the tissue of a host plant and may kill it. Water is drawn through the haustoria from the host plant's stem and xylem, and nutriments are drawn from its phloem.
Where does dodder grow?
The dodder can grow and attach itself to multiple plants. In tropical areas it can grow continuously, and may reach high into the canopy of shrubs and trees. In temperate climates it is an annual plant, restricted to low vegetation that can be reached by new seedlings each spring.
