Dodder is a parasitic plant, which has roots for support and absorption of nutrients from the host plant. what kind of roots are
devlian [24]
Dodder is a parasitic plant which has A. HAUSTORIAL ROOTS for support and absoption of nutrients from the host plant.

Dodder can not live alone. It grows from a seed and sprout from the ground but if it does not find a host within 10 days, it will die.

When the Dodder finds its host, it twines itself in a counter-clockwise direction around the stem of its host. The Dodder stem has bumps called "haustoria". These bumps are tightly pressed against the stem of the host plant and said bumps will eventually push their way inside the hosts' stem to pull the nutrients it needs to survive to the detriment of the host plant.

Dodder plant may be parasitic but it does not kill its own host instead it causes the growth of the host to be stunted.
