Name the following: (i) A parasitic pla | Class 7 Science Chapter Nutrition in Plants, Nutrition in Plants NCERT Solutions

Question:

Name the following:
(i) A parasitic plant with yellow, slender and tubular stem.
(ii) A plant that has both autotrophic and heterotrophic mode of nutrition.
(iii) The pores through which leaves exchange gases.

Answer:

(i) Cuscuta: Cuscuta has lost its chlorophyll and leaves during evolution and thus it derives its nutrition from host plant thus it is a parasitic plant.

(ii) Insectivorous Plant: Some examples are algae, bacteria and some plants. Insectivorous plants are not complete autotrophs but are partially autotrophs. They digest insects but still produce their own source of energy with light and water.

(iii) Stomata: Stomata are the tiny pores present on the epidermis of leaves. We can see stomata under the light microscope. In some of the plants, stomata are present on stems and other parts of plants. Stomata play an important role in gaseous exchange and photosynthesis; this also helps in the transpiration process.
