CBSE & NCERT Solutions For Life Processes Class 10 Notes
Today, we are going to discuss chapter 6 of Life Processes Class 10 science. In this article, we will also try to learn how to prepare Class 10 science notes.
We all have learned about a living thing. If we will roam around, we will see a lot living objects like Cow, dog, plants, teacher, parents, etc. But how we realize they are alive? We see them breathing, plants respiration and growth. Now ‘Class 10 science’ students, we will learn about the Life process in detail.
All living objects have well-organized structures, they have tissues, tissues have cells. Cells are made up of smaller components. This ordered structure can be broken down too due to various reasons. To keep this process to continue, we need to provide maintenance to them
The processes together that provide maintenance to living organism must be regular and these are the process that is very important for any organism to stay alive. This maintenance process is called life process these include processes like Nutrition and respiration. Even if we are sitting idle or sleeping we need maintenance for a living.
The process in which an organism consumes food in order to utilize the same to produce energy so that the same can be utilized for our growth and maintenance. This energy also helps us to remove waste from our body.
- Autotrophic Nutrition: – The word autotrophic is made up two words where auto means self and trophos means nourishment. So the autotrophic nutrition is simple nutrition that is obtained from inorganic substances like cordon dioxide and water. The process through which Autotrophs take in substance from outside and convert it into stored forms of energy. This process is also termed as Photosynthesis. The raw materials used in this process are carbon dioxide and water. The solar energy or light energy is converted into chemical energy
Let’s try to explain the same step by step
- Light energy/solar energy absorbed by chlorophyll
- The Light energy is then converted into chemical energy, hence splitting the water molecules
- Carbon dioxide is then reduced to carbohydrates.
6CO2+6H2O —–sunlight & chlorophyll ——–> C6H12O6 + 6O2
The raw material used in this process is derived as per below:
Carbon dioxide is taken from air and water and water & other minerals are derived from Soil.
Heterotrophic Nutrition –The word heterotrophic is derived from two words Hetro=others and trophos=nourishment. So there is some organism which depends on others for their nutrition. Eg: -Animals. This is further divided into three categories as below:
- Saprophytic Nutrition: – This nutrition is derived from organism who feed on dead and decaying plants or animal.
- Parasitic Nutrition: – This nutrition is derived from organism who derive food from other living organisms.
- Endoparasite – Parasities living inside the body of the host organism. Eg: tapeworm, hookworm
- Exoparasites – These parasites live on the body of the host Eg:- lice, mites etc.
- Holozoic Nutrition: –Some organism consumes the whole food and then with the help of enzymes break into smaller particles and digest the same. Eg: -Human beings, Animals
- Ingestion: –Food consumption
- Digestion: –Breaking of foods into smaller and absorbable form
- Assimilation: –Utilization of digested food energy
- Egestion: –Removing undigested food
We will discuss human respiration and other topics for ” CBSE Class 10 science“ in our next article.
