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 diagramof 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.
