Life Science Photosynthesis Guided Notes

Photosynthesis & Respiration

Photosynthesis

• The process by which a cell captures the energy in sunlight and uses it to make food is ______________________________

• During photosynthesis, plants use energy from the sun to convert carbon dioxide and ____________________ into oxygen and ____________________.

• Label the diagram below:

• The word equation for photosynthesis is ________________________________________________________.

• The chemical formula for carbon dioxide is _______________________.

• H₂O is the chemical formula for ________________________.

• The chemical formula for glucose is ___________________.

• 0₂ is the chemical formula for _______________________.

• Raw materials (carbon dioxide and water) are on the ___________________ side of the equation.

• ______________________ (glucose and oxygen) are on the right side of the equation.

• What happens to the products of photosynthesis?

______________________________________________________________

• What does your body do with the food that you eat?

______________________________________________________________

Respiration

• The process by which cells “withdraw” energy from glucose is called ______________________________. 

• During respiration, cells break down simple _______________________ molecules such as glucose to release the energy they contain.

• The word equation for respiration is __________________________________________________________.

• _______________________ for respiration are glucose and oxygen.

• Products for respiration are ________________________ and ______________________________.

Types of Respiration:

• _______________________________ refers to respiration that requires oxygen.

• How is aerobic respiration related to respiration?

      _____________________________________________________________

• Photosynthesis and respiration can be thought of as ______________________ processes.

• These 2 processes form a cycle that keeps the levels of ____________________ and _________________________ fairly constant in the atmosphere.

• Some cells are able to obtain energy from food without using ___________________________.

• Fermentation is an energy releasing process that does NOT require ______________________.

• Some _________________________ organisms live where there is no oxygen, such as deep oceans or in the mud of lakes and swamps.
