CH 1 NUTRITION IN PLANTS # Mind Map:  # Concept Map: #flow chart for nutrients: KEYWORDS: 1.)   Nutrition - is a process by which organisms take in the food and utilize it in order to survive. Based on the mode of nutrition organisms can be divided into two categories. 2.)   Autotrophic Organisms  - They can prepare their food by themselves most green plants are autotrophic in nature. 3.)   Heterotrophic Organisms  - They depend upon other organisms for their food such as animals 4.)   Parasitic Plants  - Some plants live on another plant for their nutrition. These are called parasites. The plants on which these parasitic plants survive are called the host. For Example, cuscuta is a parasitic plant. 5.)   Insectivorous Plants  - Some plants depend upon insects for the food and thus are called Insectivorous. The leaves of these plants are modified into a pitcher like structure. The top

Q. Solutions to Boojho and Paheli’s questions from the text: (NCERT) 1. Boojho wants to know how plants prepare their own food. Ans: Plants prepare their own food by taking up raw materials from the surrounding like carbon dioxide (co2), water, and minerals in the presence of sunlight by a process known as photosynthesis. 2. Paheli wants to know why our body cannot make food from carbon dioxide, water and minerals like plants do. Ans: Our bodies do not have chlorophyll which is required for the process of photosynthesis to make food from carbon dioxide, water and minerals like plants do. 3. Boojho wants to know how water and minerals absorbed by roots reach the leaves. Ans: Water and minerals absorbed by the roots are transported to different parts of the plants through pipe like structures known as vessels that run throughout the roots, stem and leaves of the plants. 4. Paheli wants to know what is so special about the leaves that they can synthesize food bu
