2] 22 pts. We have been studying the primary tissues of a typical seed plant. We have used the conventional concept of what constitutes a tissue. We have Not been using the radical simplification of plant tissues advanced by the author.

A] What is the tissue which produces all other tissues in the primary plant body? ______________________

Hint Hint - I use it as the reference point for cell differentiation & it is the LEAST Differentiated tissue

B] Identify 3 of its distinguishing features. This can include a specific function.

1] ____________________________________________________

2] ____________________________________________________

3] _____________________________________________________

C] The above tissue produces the 3 primary meristems. Identify these

1] _____________________________________________________

2] _____________________________________________________

3] _____________________________________________________

D] The primary meristems produce primary tissues. Identify these using general terminology.

1] ____________________________________________________

2] ____________________________________________________

3] ____________________________________________________

E] Each of these tissues produces several different types of cells. Identify 3 different cell types for primary tissue. First identify the tissue, then identify the 3 different cell types

Example 0] Tissue Type: Bluphozema - Cell Types a] Angst b] Crankst c] Trankst

1] Tissue Type _______________________________________

Cell Types a] _____________________ b] ______________________ c] ________________________

2] Tissue Type _______________________________________

Cell Types a] _____________________ b] ______________________ c] ________________________

3] Tissue Type _______________________________________
Cell Types a] _____________________ b] ______________________ c] ________________________

3] 15 pts Plastids are the most characteristic organelles of plants. Identify four different types of plastids and make a labeled outline sketch of each which illustrates the differences between them. Briefly state the primary function of each. If you are not comfortable drawing, use sentences.

Plastid 1 ID _______________________

 

Function _________________________________________________________________________________

Plastid 2 ID _______________________

 

Function _____________________________________________________________________________

Plastid 3 ID _______________________

 

Function ______________________________________________________________________________

Plastid 4 ID _______________________

 

Function _________________________________________________________________________________

4] 15 pts. Consider Secretion and the Epidermis.

A] Identify and label a sketch of a real or model example of the most simple type of secretory structure found in the epidermis. Hint Hint - you would not like to lie down on these.

 

 

B] Identify and label a sketch of a real or model example of the most complex type of epidermal secretory structure we studied. Hint Hint - Their motto is Stick Around!

 

D] Identify and label a sketch of a real or model example of an intermediate type of epidermal secretory structure that is typical for mints and other fragrant herbs.

 

Identify 3 potential Functions of secretory trichomes

A] _________________________________________________________________________________

B] __________________________________________________________________________________

C] __________________________________________________________________________________

5] 11 pts. The epidermis produces a range of non-secretory trichomes. Make a series of labeled sketches which illustrate [A] the most simple type of non-secretory trichome [B&C] two intermediate types which lead to the most complex type [D]. These can be idealized drawings rather than drawings of actual plants that we examined. Hint Hint The most complex types are found in Olive and Tillandsia (ume ume a Dole) = Spanish Moss.

 

Identify 3 Functions of any non-secretory trichome

A] _________________________________________________________________________________

B] __________________________________________________________________________________

C] __________________________________________________________________________________

6] 12 pts. The Cell Wall is a very important secretion by plant cells.

1] Identify the structures indicated below and briefly explain D] what is happening in the drawing

A] ___________________________

B] ___________________________

C] __________________________

D] ____________________________

2] Do the same as A. E = Explain what is Happening

A] ___________________________

B] ___________________________

C] __________________________

D] ____________________________

E] _____________________________

_____________________________

7] 15 pts. Identify the major classes of components which are typically present in primary cell walls.

A] _________________________________________________

B] _________________________________________________

C] _________________________________________________

D] Which of these is most responsible for the strength of cell walls? _____________________________

E] What is the major difference observed for D between primary and secondary cell walls? Hint hint. Remember the cotton fiber.

_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

F] Identify two different, addition types of chemicals which can be found in cell walls. Identify one tissue in which these are found & briefly state the function of each

1] ID _____________________________

Tissue ____________________________

Function __________________________________________________________________________________________________________________________________________________________________

-----------------------------------------------------------------------------------------------------------------------------------

2] ID _____________________________

Tissue ____________________________

8] 12 pts. Identify the tissue in the illustration below ______________________________

Rearrange the letters of each to achieve the correct order of differentiation from the center of the plant (Left side of page to the outside of the plant (Right side of page).

Letter _______________ ___________________ ____________________ ______________________

Use the letter currently assigned to each and match this with the term below. Warning some of these may have multiple correct matches. They all have at least 1 correct match.

Primary Cell Wall ____________________________________________

Secondary Cell Wall __________________________________________

Pits ________________________________________________________

Annular Rings ________________________________________________

Scalaraform Wall Thickenings ___________________________________

Proto (use the ONE which is the best for this) _______________________

Meta (use the ONE which is the best for this) _______________________

Clearly state the rationale for Mauseth's argument that there are only 3 tissues in plants.

Rebut this assertion!!!
