Video Notes #9 – Photosynthesis and Cellular Respiration
REVIEW Circle the Correct Answer and explain why - True or False - Plants are
autotrophs and eukaryotes.
This is true – plants are autotrophs which means they have the ability to make
their own food using the many cells that are in their cell bodies. Being multicellular
organisms makes them eukaryotes.
Objective 33: I can define photosynthesis, cellular respiration, transpiration,
cuticle, stomata:, guard cells, chloroplasts and glucose.
•
Photosynthesis: is the process by which plants use to create
.
: is the process where food is broken down into
•
energy.
•
Transpiration: is the
of water from plants.
•
Cuticle:
•
Stomata:
•
Guard cells: surround and control the size of the opening in stomata.
•
Chloroplasts:
•
Glucose: the sugar that is produce from photosynthesis.
Objective 34: I describe the characteristics and the process of photosynthesis.
During
, radiant (light) energy from the Sun is converted
into chemical energy through a chemical reaction. The
(a type of
sugar) that is produced is used both to keep the plants alive and stored by plants
to be used by animals that then eat the
.
Characteristics of Photosynthesis
Food Accumulated
Carbon Dioxide taken in
Oxygen released
Requires carbon dioxide and water
Occurs only in the presence of chlorophyll
Sunlight Powers Photosynthesis

This seedling is soaking up the sun.


Within its leaves, photosynthesis is converting sunlight into food.
Plants & other producers need a few simple ingredients to make their own food:

Photosynthesis is a series of chemical reactions that yields two important
products:
Photosynthesis Occurs in the Chloroplasts
Gas exchange occurs at leaf pores called stomata.
Each cell contains several chloroplasts.
Chloroplasts capture energy from sunlight.
Objective 35: I can describe characteristics of cellular respiration.
Cellular Respiration is the process by which cells, in
, use oxygen for
breaking down sugar to release the stored energy.
Objective 36: I can describe the relationship between photosynthesis and cellular
respiration.
Characteristics of Cellular Respiration
Energy of glucose released
Carbon Dioxide released
Oxygen taken in
Occurs in light or dark
