Plant Physiology Practice

1.01a I can identify and describe the parts of a plant.

  1. Horticulture is the art and science of _________________________________.
  2. Leaves
    1. Sketch and label a leaf and stem showing leaf, petiole, blade and stipule.
    2. On the leaf pattern specimens identify: leaf __, petiole __, blade __, stipule __.
    3. Sketch the following pattern of leaf attachments: alternate, opposite, whorled.
    4. On the leaf pattern specimens identify: opposite __, alternate __, whorled __.
  3. Stems
    1. Sketch a dicot and monocot stem cross-section. Label the sketches as monocot or dicot, indicate the vascular bundles.
    2. Sketch an actual woody dicot stem and label these features: axial bud, internode, leaf scar, node, terminal bud scar, terminal bud.
    3. On the woody dicot stem specimen identify a(n):
      axillary bud __, internode __, leaf scar __, node __, terminal bud scar __, terminal bud __.
  4. Roots
    1. The two main root systems are __________ and _________.
    2. Identify the root system specimens: fibrous __, tap __.
    3. Sketch a root system and label these features: root, root cap, root hairs.
  5. Vascular System
    1. Describe the parts of the plant needed for the vascular system.
  6. Meristem
    1. Describe the meristematic parts of the plant.
    2. Define a bud.
    3. Sketch a woody dicot stem showing the locations of meristem tissue. Label shoot and root apical meristems, lateral meristem (vascular cambium and cork cambium).
    4. On the woody dicot stem specimen identify two locations of apical meristem: ___ and ___.
    5. On the log section identify the vascular cambium: _____

1.01b I can relate the parts of a plant to their functions.

  1. What is the primary function of leaves?
  2. What are the primary function(s) of stems?
  3. What are the primary function(s) of roots?
  4. What are the primary function(s) of the vascular system?
  5. Compare and contrast the functions of xylem and phloem.
  6. What are the primary function(s) of meristem?
 

1.02 I can describe cellular theory and cellular structures through knowledge of the plant processes (including photosynthesis, respiration, transpiration and vascular systems).

  1. Photosynthesis
    1. Explain the function of photosynthesis.
    2. Write the chemical equation for photosynthesis.
    3. Describe the parts of the plant needed for the photosynthesis system.
  2. Respiration
    1. Explain the function of respiration.
    2. Write the chemical equation for respiration.
    3. Describe the parts of the plant needed for the respiration system.
    4. Compare and contrast respiration and photosynthesis.
  3. Transpiration
    1. Explain two functions of transpiration.
    2. Describe the parts of the plant needed for the transpiration system.
    3. Explain the dilemma of plants growing in hot dry regions.
    4. Explain how sunken stomata, 'hairy' leaves, small leaves and alternative photosynthetic processes such as CAM and C4 are transpirational adaptations.
  4. Vascular System
    1. Explain the function of the vascular system.
    2. Explain how transplant shock is a failure of the vascular system.
  5. Plant Growth and Development
    1. Compare and contrast growth and development.
    2. Compare and contrast primary and secondary plant growth.
    3. Explain what we mean when we say meristem is capable of differentiation.
    4. Contrast apical and lateral meristems.

1.03 I can examine and hypothesize about plant variations.

  1. Describe a leaf structure variation and its adaptive purpose.
  2. Describe a stem structure variation and its adaptive purpose.
  3. Describe a root structure variation and its adaptive purpose.
