Answer:
1] Sucking or Haustorial roots – These roots are found in parasitic plants. Parasites develop adventitious roots from the stem which penetrate into the tissue of the host plant and suck nutrients. Examples: Cuscuta (dodder), Cassytha, Orobanche (broomrape), Viscum (mistletoe), Dendrophthoe.
2] In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck, wrist, at the groin, behind the knee, near the ankle joint, and on foot.
