Refer to Textbook pg. 136 to 137
The primary function of a leaf is __________________________________________________
Photosynthesis word equation:
Glucose is a carbohydrate, which can be converted into other carbohydrates in the leaf.
________________ is used as a source of stored chemical energy or it is used as the basic
building blocks for all of the complex _____________________ and _____________________ it
needs to make.
Cellular Respiration is the ______________________ of energy from_____________________.
All plant and animal cells use cellular respiration to get energy from glucose and oxygen in this
word equation:
Glucose + Oxygen
Carbon Dioxide + Water + Energy
This is the opposite of photosynthesis!
Absorbing Light
Why are leaves generally wide and thin?
What causes the green colour in plants?
Tissues and Cells in the Leaf
Palisade Layer
Spongy Mesophyll
Location
How are they packed?
Type of Tissue
Why is the palisade layer packed closely together whereas the spongy mesopyll is more loosely packed?
Label this diagram
of the cross section
of the leaf
Obtaining Carbon Dioxide
Carbon dioxide gas is ____________________________________________ in low concentrations.
Cuticle –
Stomate –
Guard Cells -
Where are the stomata located and why?
When would stomata open?
When would they close?
How to guard cells open and close? Connect this to your knowledge of the vacuole in plant
cells.
How to plants obtain water?
Homework: pg. 139 #2-7, also make a table comparing plant and animal systems.
