The plant on which a parasite climbs to derive its nutrition is called the host plant. Host plant aids, shelters, or protects another plant in its growth. A host is a larger organism that harbours a smaller organism; whether parasitic, mutualistic, or symbiont. The guest is typically provided with nutrients and shelter.

Observe the picture and answer the question. It is beautifully coloured. Why?

The given picture is of a pitcher plant. The pitcher plant is beautifully coloured so that it can easily attract insects towards them. It is an insectivorous plant that eats insects to obtain nutrients. The pitcher plant is shaped like vase and resemble flowers in look and smell.

1-b. Some plants lack chlorophyll, and they can not prepare their own food, so they climb on other plants known as host to obtain their nutrition, this mode of nutrition is called the parasitic mode of nutrition. The plant which feeds in the host is known as a parasite. For example- Cuscuta. 2-c. Organisms which can not prepare their own food and depend on others for their food are called as heterotrophs and this mode of nutrition is called heterotrophic mode of nutrition. For example- animals. 3-d. Some plants feed on other insects to fulfil their nutritional requirement. Such heterotrophic plants are called as insectivorous plants. For example- Pitcher plant. 4-a. Organisms which feeds on dead and decaying matter to obtain their nutrition are called saprotrophs and this mode of nutrition is called saprotrophic mode of nutrition. For example- Fungi. 5-e. The relationship where two organisms live together for mutual benefit is called symbiotic relationship. Lichen is a symbiotic association between a fungi and algae. Column A Column B 1.
