Using Pgs. 718-719 name the three types of tissue
systems found in plants. Rank the tissues according to
their flexibilities?
How can we tell the difference between Parenchyma,
Collenchyma, and Sclerenchyma?
Tracheids and vessel elements are part of the vascular
tissue called
.
How is the stele in monocots different from the stele in
the dicots? How is the pith different from the cortex?
(see pg. 717)
How is primary growth different from secondary
growth? The specific areas that plant grow in their body
are known as
.
An increase in girth is due to cell division occurring in
the
.
Introductory Questions #2

Why is the amount of humus and the particle size of soil so
important to plants?
How is a monocot root different from a dicot (eudicot) root?
(See the cross sections on pg. 722)
Where is the casparian strip located?
Why must plants use active transport in order to take in ions
into the root hair cells? Which ion are most difficult for plant to
obtain?
Give three examples of micronutrient and three examples of a
macronutrient that plants require. (see chart on pg. 758)

If a stem develops only by primary growth (apical
meristems) then that stem is not woody it is
_____________ (common in monocots)
Name the two types of lateral meristems seen in
woody plants. What purpose do rays serve?
As the vascular cambium divides it grows in two
directions forming the _________ _______ toward
the inside and the __________ ______ toward the
outside.
How is summer wood different from spring wood?
Why must plants open their stomata? When does
this usually occur?

What is the driving force behind the movement of
water in the xylem and sugar through the phloem in
plants?
As Sugar is produced in the leaves during
photosynthesis, what is the driving force to move
the product down the plant (other than gravity)?
What is considered to be the “source” and what is
considered top be the “sink”? Why is this
movement explained by the “pressure-flow
hypothesis”?
Briefly explain what guttation is and why it is more
significant in smaller plants. (pg. 746) Why does
this occur at night? How much water pressure can
accumulate in the roots? Name the three solutes
that accumulate in the guard cells allowing for water
to move in. What type of protein channel allows for
potassium to enter into the cell?

How is a pinnate leaf different from a palmate leaf?
Name the two mesophyll cell layers in a dicot leaf. How
are these two layers different from each other?
Name the two types of cells that make up the mesophyll
layers in a dicot leaf. What kind of tissue (cell types)
are they?
Briefly explain how the stomata open and close. Name
the ions involved. What color light cause the stomata to
open?
Name three factors that can affect transpiration in
plants.
Introductory Questions #6
1. From chapter 10, what did Engelman’s
experiment show regarding
photosynthesis? What did he use to
determine the rate of photosynthesis?
2. How do plants absorb light energy? Name
some features that allow plants to absorb
light. What are some differences between
chlorophyll a and chlorophyll b?
3. Which reactant does the oxygen produced
from photosynthesis directly come from
4. Where specifically do the light and dark
reaction take place within a plant cell?
Introductory Questions #7
1) Name the three parts that make up a photosystem.
2) How does NADPH differ from NADH?
3) What does it mean when we “FIX” carbon? Does
this happen in the light or dark reactions?
4) What is required in order for the light reactions to
proceed?
5) How does non-cyclic photophosphorylation differ
from cyclic photophosphorylation? Which process
is more common?
Introductory Questions #8
1) Name the three phases of the Calvin Cycle.
Which phases require ATP and how much ATP
would be needed for producing on glucose
molecule?
2) What are the substrates that attach to the active
sites of Rubisco?
3) How does a C3 plant differ from a C4 plant? Give
3 examples of a C3 & C4 plant.
4) What happens as a result of stomata closing?
5) Which type of plant undergoes photorespiration?
Does photorespiration occur at night or during
the day? How is photorespiration different from
cellular respiration seen in the mitochondria?
6) How are C4 and CAM plants similar and how are
they different? Give an example of both.
