    BI 102 Lab Worksheet: Plants I Name _________________________________ Section _______

    STATION I: Plant Diversity

    • List each of the angiosperms at Station 1 in the table below, and identify each of those plants as either a monocot or a eudicot. Also list the characteristic(s) you used to determine whether each is a monocot or a eudicot.
    Plant Name Monocot or Eudicot? Characteristic(s) used to determine monocot or eudicot
         
         
         
         
         
         
         

    STATION II: Root Anatomy & Diversity

    2. Write the number(s) on the structures on the root model next to the correct names of the structures below:

    _____ Apical meristem

    _____ Cortex

    _____ Epidermis

    _____ Phloem

    _____ Root cap

    _____ Xylem

    3. Based on its roots, is the grass a monocot or a eudicot? What about the dandelion?

     

     

    4. What is the function of adventitious roots in ivy or Virginia creeper?

     

     

    5. What are the functions of prop roots in corn?

     

     

    STATION III: Stem Anatomy & Diversity

    6. Write the number(s) on the structures on the monocot stem model next to the correct names of the structures below:

    _____ Cortex

    _____ Epidermis

    _____ Phloem

    _____ Vascular bundle girdle

    _____ Xylem

    7. Write the number(s) on the structures on the eudicot stem model next to the correct names of the structures below:

    _____ Cortex

    _____ Epidermis

    _____ Phloem

    _____ Vascular bundle girdle

    _____ Xylem

    8. What is the major difference between the arrangement of vascular bundles in monocot and eudicot stems?

     

    9. Onions and potatoes grow underground. However, they are not considered root vegetables. Why not?

     

    10. Pick at least two of the provided “tree cookies”, and list the species you chose, and your estimates of their ages below:

    Tree species

    Estimated age (years)

       
       
       

    STATION IV: Leaf Anatomy & Diversity

    11. Write the number(s) from the leaf model next to the correct names of the structures below:

    _____ Chloroplast

    _____ Cuticle

    _____ Lower epidermis

    _____ Palisade mesophyll

    _____ Phloem

    _____ Spongy mesophyll

    _____ Stoma

    _____ Upper epidermis

    _____ Vascular bundle sheath

    _____ Xylem

    12. In the space below, sketch a monocot leaf and a eudicot leaf, making sure to illustrate the differences in the arrangement of their veins. Label each picture as either a monocot or a eudicot, and also give a description of the arrangement of their leaf veins.

     

    13. Knowing that the spines on the provided cactus are actually modified leaves, what is the green portion of the cactus at this station, and where (in what structure) would photosynthesis occur in this cactus?

     

    14. What specific tissue in the celery stalk is stained the same color as the colored water? How did you come to this conclusion?

     

    15. What is the botanical difference between herbs and spices?

     

     

    STATIONS V-VI: Microscopic Examination of Plant Tissues

    16. Look at the slide showing a longitudinal section of a root with root hairs on its surface. What do you think might be the function of root hairs?
