     Procedure:
     1. Use a cut carnation and place the stem (or a cut portion of the stem) in a test tube of colored
        water. Leave overnight. Observe the following day(s).
     2. Present and defend a hypothesis as to how the dye ends up in our flower.

Internal Stem Lab

Background:
Monocot and dicot stem vascular tissue is arranged in different patterns that allow us to classify a plant based on microscopic viewing of
a cross section of the stem. In today’s lab we will try to identify characteristics that will allow us to tell the difference between the two
classes of plants. Use your notes to answer the pre-lab questions.

      1. What makes an herbaceous stem different from a woody stem?


Procedure:
Draw detailed illustrations of a monocot and dicot stem below. Label: xylem and phloem.

                         Monocot                                               Dicot




Questions:
  1. What is the job of the phloem in a plant?

     2. What might be found inside the xylem of a plant?


     3. What are the walls of the xylem made out of?
   4. What is one job of the vascular cambium?



   5. Where do we get more phloem from in the cell? (Hint: what process makes phloem)




   6. Describe some differences between a monocot and a dicot.



Root Lab

Background:
Water enters the plant through the root. Roots are incredibly tough growing through hard, compacted
soils in search of water. Use your notes on roots to answer the following pre-lab questions.

Procedure:
    1. Cut a parsnip root cross section as demonstrated in class. Place the thinnest layer possible on
       a microscope slide adding a drop of Iodine solution stain. The iodine will stain the starch
       granules that store this molecule blue/black.
    2. Draw a pie shaped illustration of this cross section below:
       Label root hairs, phloem, and xylem.


    1. Where in the root is the xylem located?


    2. What type of cell division is used to make
    more root cells?



    3. Parsnip has very tiny hairs to intake water from the soil. Draw what the structures would look
       like if you could see it under the microscope.


    4. What part of the parsnip contributes to the sweet taste of this root vegetable?


    5. What does the plant do with the starch stored in the root?
Draw a Buttercup root here:                               Draw a Tilia Root here:




   1. How can you tell that the buttercup root is a dicot? Label the xylem and phloem.



   2. Determine if Tilia is a dicot or a monocot? How can you tell? Label the xylem and phloem.




   3. Investigation: Search on-line for a picture of a monocot root and paste it here. What is the
      difference between a dicot root and a monocot root?
Label the following pictures:
                                                            Monocot or dicot? Root or stem?

                                                                         How do you know?




                                                A                 What is A pointing too?




                                                            Monocot or dicot? Root or stem?

                                                                         How do you know?



                                                        A              What is A pointing too?




                                                            Monocot or dicot? Root or stem?

                                                                         How do you know?


                                Alfalfa dicot       A                What is A pointing too?
