NCERT Science Notes for Class 7 (Part 1) 1.1- Mode of Nutrition in plants

 Hello friends, so today we are going to start Chapter one of science Class 7. 

 

Today we are going to cover important points of 1.1- Mode of Nutrition in Plants  and there will be some additional information too.

 

1. Plants are the only organisms which can make their own food by using simple substances like water (H₂O) and carbon-dioxide (CO₂).

 

2. Nutrition is mode of taking food by an organism and utilizing nutrients from food by body.

 

3. Some organisms make their own food, and these organisms are called Autotrophs (Auto=self and trophos=nutrition). They are also called the producers in the food chain.

 

4. Plants are Autotrophs and make their own food by photosynthesis. Animals and most of the other animals indirectly or directly depend on plants for food. These organisms are called Heterotrophs (hetero=other and trophos=nutrition)
