I hope you like the notes on CBSE Class 7 Science Chapter 1 that is Nutrition in Plants. Along with carbohydrates, plants can also produce proteins and fats which are formed with the help of Nitrogen. Therefore, all of the living organisms directly or indirectly receive their energy from the Sun. Hence they are unable to prepare their food by themselves. There are 17 most important nutrients for plants. Hence, chloroplasts allow the conduction of the process of photosynthesis. These plants are green and carry out photosynthesis. Green plants make all nutrients that are needed by using carbon dioxide, water and minerals with the help of chlorophyll (green pigment) and energy from sunlight. (olympiads). Sometimes an organism that contains chlorophyll such as algae lives in association with a fungus (together called as Lichens). All living organisms are made from small building units of catted cells. However, in case of some desert plants, it takes place in their stem and even branches. The bacteria provide a plant with nitrogen that they fix and in turn, they get shelter and food from the plant. The chloroplasts convert the sunlight into sugars that are used by the plant cells. Rhizobium is a type of bacteria that convert atmospheric nitrogen into a soluble form that can be utilised by plants. Nutrition in Plants Class 7 Notes Understanding the Lesson 1.
