Fundamental Unit of Life_4 ( light and dark photosynthesis)

State the site of light and dark phase of photosynthesis. What is the first statement of this video?

• Photosynthesis takes place in two major phases. They are Light reaction and Dark reaction.

• In light reaction, light plays an important role.

  
  

• Here, a series of chemical reactions takes place one after

  another initiated by light.

• Hence this phase is technically termed as photochemical phase

• The reactions of the light take place in Thylakoid membrane

  which is present in chlorophyll

State the site of light and dark phase of photosynthesis. What is the fourth statement of this video?

• Thylakoids are termed as grana of chloroplasts.

• Following are the steps involved in light reaction.

• Step one when sunlight falls on the plant the chlorophyll present on the leaf absorbs light energy and becomes activated

  
  

• Hence this phase is technically termed as photochemical phase

• The reactions of the light take place in Thylakoid membrane

  which is present in chlorophyll

State the site of light and dark phase of photosynthesis. What is the fifth statement of this video?

• Thylakoids are termed as grana of chloroplasts.

• Following are the steps involved in light reaction.

• Step one when sunlight falls on the plant the chlorophyll present on the leaf absorbs light energy and becomes activated

• The absorbed energy excites electrons to the higher energy level

  
  

• The reactions of the light take place in Thylakoid membrane

  which is present in chlorophyll

State the site of light and dark phase of photosynthesis. What is the sixth statement of this video?

• Thylakoids are termed as grana of chloroplasts.

• Following are the steps involved in light reaction.

• Step one when sunlight falls on the plant the chlorophyll present on the leaf absorbs light energy and becomes activated

• The absorbed energy excites electrons to the higher energy level

• This energy is used to split the water molecules into two-component ions which are given by the equation

• This energy is used to split the water molecules into two-component ions which are given by the equation

State the site of light and dark phase of photosynthesis. What is the ninth statement of this video?

• 
• The arrow reaction is termed as photolysis which means splitting by using light that is photo light lysis breaking

  .

• Step 3: The highly reactive ions of water
  

  $H_{2_{ }}O$ split in two different directions as hydroxide ion (OH−) and hydrogen ions (H+).

• The absorbed energy excites electrons to the higher energy level

• This energy is used to split the water molecules into two-component ions which are given by the equation

State the site of light and dark phase of photosynthesis. What is the tenth statement of this video?
