(i) Cuscuta (ii) china rose (iv) pitcher plant (iv) rose
(a) (ii) Parasite
An example of parasite plant is Cuscuta which is also known as Amar bail. Cuscuta plant does not contains chlorophyll that is why it is not green in colour. We can see Cuscuta plant a yellow, oragne tubular structure twining around the stems and branches of a tree. It cannot synthesise its own food because of lacking of chlorophyll. Cuscuta plant takes readymade food from the tree on which it climbs.
(b) (iv) Pitcher plant
It is a different carnivores plant which can trap insects and digest them. The pitcher-like or jug-like structure is the modified part of leaf also known as pitfall traps. The leaf's apex forms a lid which are able to open and close the mouth of the plant. Inside the pitcher there are hair which are directed downwards and inwards. When an insect falls in the pitcher, the lid get closed and the trapped insect gets entangled into the hair. The insect is then digested by the digestive juices that are secreted in the pitcher and its nutrients are absorbed. These insect-eating plants are called insectivorous plants.
