Life Processes- NUTRITIONS 1


                                                TOPIC - LIFE PROCESSES
                                                           CLASS 10

Dear students,
Thank you for taking the first step and logging in! you are wonderful! 😊😊

LESSON 1
This is our first class for this chapter. At the end of the blog you will be able to:
1) Identify various life processes.
2) Know the importance of these processes.
3) Define nutrition.
4) Study the two main types of nutrition and distinguish between them.

Happy learning!

PLEASE COPY EVERYTHING IN YOUR BIOLOGY NOTEBOOK EXCEPT THAT WHICH IS WRITTEN IN RED. KEEP YOUR NCERT WITH YOU FOR ANY REFERENCE.INTRODUCTION

HOW DO WE KNOW THAT AN ORGANISM IS ALIVE?
If an organism shows any kind of movement, we say that the organism is alive. 
Animals move, breathe (chest moves up and down) - they are alive.
What about plants?  - there is no visible movement - they are green.

Molecular movements are needed for life- building up processes - making of food , breaking down processes - food is digested, various cells move in the body etc. REFER TO PAGE 93 NCERT . READ IT.

LIFE PROCESSES- The processes which together perform the maintenance job and are essential for sustaining life are called life processes.
Nutrition, Respiration, Transportation, Excretion are important life processes.


For an organism to grow, food (raw materials) is required from outside. These outside raw materials are carbon based molecules. Hence nutrition is important. 
READ PAGE 94.

NUTRITION –is a process by which living beings obtain food or synthesize it and change it into simple absorbable form by a series of biochemical processes.
                                                      
     

                                                         TYPES OF NUTRITION
     
            AUTOTROPHIC NUTRITION                                             

     1.Nutrition in which an organism makes its own food from simple inorganic materials
         Like co2 and water.
      2. It occurs in green plants.

        HETEROTROPHIC NUTRITION
   
1.Nutrition in which an organism cannot make its own food, take in complex food
And break it down into simple forms Using enzymes.
2. It occurs in plants that lack chlorophyll,Insectivorous plants and animals.

I hope it helped, dear students. Please do the following assignment. 

ASSIGNMENT ( ANSWERS FROM PAGE 95)

Q1) WHAT ARE AUTOTROPHS? GIVE TWO EXAMPLES.
Q2) WHAT ARE ENZYMES?
Q3) IN WHAT FORM DO PLANTS AND ANIMALS STORE THEIR FOOD ?

See you in the next class! 
Take Care😊😊

SOURCES OF ENERGY     Important Instructions: (i) Keep your text book open for reference. (iv) Home Assignment need to be done in your physics note book. (v) Complete your index, put chapter name, date, Physics note book. (vi) Important links are provided in the blog for better understanding. Home Assignment to be done in the Physics copy  After this class, you will be able to: identify the parameters needed to classify a source as a good energy source. interpret the advantages of using fossil fuels, thermal power plants and hydro power as sources of energy INTRODUCTION Energy is the ability to do work or the total power derived from our natural resources.  The energy exists in many forms and can be converted from one form of energy into another.  Energy is mainly derived from natural sources like the sun, oceans, fossil fuels, wind etc and is converted into electrical energy that we consume for o...

SOURCES OF ENERGY Lesson 4    Hello everyone! I hope you are keeping well and taking good care of yourself! Learning outcomes : explore alternate sources of energy giving prime importance to environmental  conse q uences All  energy sources  have some  impact  on our  environment .  Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable  energy sources  by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. No source of energy can be called pollution-free, because, the use of any source of energy disturbs the environment in one way or the other.  A source of energy like a solar cell is pollution free in actual operation but the assembly of the device might have caused some damage to the environment. So, in absolute sense,  no source of energy can b...

CLASS 10 CHAPTER 7  CONTROL AND COORDINATION Day 7 Dear Learners, Thank you for Logging in! You're wonderful!😊  Note: Content written in blue should be recorded as notes in the Biology Notebook. At the end of this class, you will be able to: 1. Estimate different types of plant hormones and their functions. 2. Explain the release of Auxin. Happy Learning!😊 PLANT HORMONES Chemicals that help plants to coordinate their growth and various other activities are called plant hormones. They are secreted in small amounts by some specialized parts of the plants. (to be written in bio notebook) Release of Auxin 1. When a growing plant detects light, auxin synthesizes at the shoot tip. 2. It helps the cell to grow longer. 3. When light is coming from one side of the plant, auxin diffuses towards the shady side of the shoot. 4. The concentration of auxin stimulates the cell to grow longer on the other side of the shoot which is away from light. 5. ...
