Match the following: Column A Column B 1. Cuscuta (Amarbel) a. saprotrophs 2. Animals b. parasitic plant 3. Pitcher plant c. heterotrophs 4. Fungi d. insectivorous plant 5. Lichen e. symbiotic relationship

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. Cuscuta (Amarbel) b. parasitic plant 2. Animals c. heterotrophs 3. Pitcher plant d. insectivorous plant 4. Fungi a. saprotrophs 5. Lichen e. symbiotic relationship

Match the columns: Column A Column B i.Dodder plant (a) Urinary bladder ii. Mulberry leaves (b) Parasite iii Eyes (c) Stomata iv. Urine collecting sac (d) Food of silkworm v. Plants (e) Potato

i. Dodder plant - b. Parasite The dodder plant is a parasite plant. A parasitic plant is a plant that derives some or all of its nutrients from another living plant. ii. Mulberry leaves - d. Food of silkworm The silkworm lays its eggs on mulberry leaves which later form larva which feeds continuously on the mulberry leaves. This later forms a cocoon around which is used to obtain silk threads. iii. Eyes - e. Potato. A potato is a stem that is modified to store food. It has buds on its surface called eyes. iv. Urine collecting sac - a. Urinary bladder. Urine is the liquid waste produced by the kidneys. It is collected in a bladder called the urinary bladder. v. Plants - c. Stomata. Small pores present on the leaves for the exchange of gases in leaves are known as stomata. They have chlorophyll pigment that absorbs sunlight in the process of photosynthesis. Column A Column B i. Dodder plant (b) Parasite ii. Mulberry leaves (d) Food of silkworm iii Eyes (e) Potato iv. Urine collecting sac (a) Urinary bladder v. Plants (c) Stomata

Match the items in Column A with the items in Column B. Column A Column B 1. Dodder ( Cuscuta ) (a) Saprophytes 2. Lichen (b) Insectivorous 3. Indian pipe (c) Autotrophs 4. Venus flytrap (d) Bacteria 5. Green plants (e) Symbiosis (f) Parasite

1- (f) Plants or animals which live in (or on) other living organisms and derive their food from them are called parasites . Dodder is an example. It has haustoria for the absorption of food from the host plant. 2- (e) The interaction between two organisms in which both partners get benefited from each other is called symbiosis or mutualism. Lichen is a typical example of symbiosis because of the mutual relationship between an alga and a fungus. The fungus absorbs water and minerals to share with the alga whereas the alga supplies organic food to the fungus. 3- (a) Plants that live and feed on dead or decaying organic matter are called saprophytes. Since Indian pipe derives food from dead or decaying matter, it is a saprophyte . Saprophytes are mostly fungus and/or bacteria. 4- (b) Plants that derive their nutrients by trapping and consuming insects are known as insectivorous plants. Venus flytrap is an example. 5- (c) Autotrophs are organisms that can prepare their food from simple inorganic substances. Green plants are examples as they prepare their food through the process of photosynthesis. Column A Column B 1. Dodder ( Cuscuta ) (f) Parasite 2. Lichen (e) Symbiosis 3. Indian pipe (a) Saprophytes 4. Venus flytrap (b) Insectivorous 5. Green plants (c) Autotrophs
