CHAPTER: LIFE PROCESS

Date: 2/04/2017

1.   What are the different types of life process?

     Answer:    The different types of life process are:

                    1. Respiration

                    2. Digestion

                    3. Transportation

                    4. Excretion

                    5. Nutrition  

 2. Define Autotrophic nutrition.

  Answer:    Autotrophic Nutrition means the type of Nutrition in which the organisms make their own food. The process by which these organisms make their food is known as Photosynthesis and this process is performing by green plants and green algae.

   3.  Define Heterotrophic Nutrition.

   Answer:      It is the type Nutrition in which the organisms do not make their own food and hence they are dependent on other organisms for food. Example - Human, animal, and Bird etc.

4. What are the various steps of photosynthesis?

   Answer:    steps involve in the process of photosynthesis are: 

1. The green pigment present in the leaves of the green plant called                              chlorophyll traps the sunlight in the leaves.

2. The step change the light of the sun into energy which help to start the process of making food.   

3. Then the root take up all the nutrients and water from the soil to the                     leaves and then the leave mix the water, Nutrient and carbon dioxide to                    make food.

4. And then the plant release the waste out (oxygen)

      Therefore the equation for photosynthesis is:
                                       6CO2 + 6H2O + light energy = C6H12O6 + 6O2.

5. What is the different function of stomata?

Answer: 
 a. Stomata help the plant to exchange gases during the process of                                                  photosynthesis

 b. It also help the plant in the process of transpiration and therefore the plants                             are able to control their water storage
