Plant Physiology Practice 2013
1.01a I can identify and describe the parts of a plant.
- Horticulture is the art and science of _________________________________.
- Sketch and label a leaf and stem showing leaf, petiole, blade and stipule.
- On the leaf pattern specimens identify: leaf __, petiole __, blade __, stipule __.
- Sketch the following pattern of leaf attachments: alternate, opposite, whorled.
- On the leaf pattern specimens identify: opposite __, alternate __, whorled __.
- Sketch a dicot and monocot stem cross-section. Label the sketches as monocot or dicot, indicate the vascular bundles.
- Sketch an actual woody dicot stem and label these features: axial bud, internode, leaf scar, node, terminal bud scar, terminal bud.
- On the woody dicot stem specimen identify a(n):
axillary bud __, internode __, leaf scar __, node __, terminal bud scar __, terminal bud __.
- The two main root systems are __________ and _________.
- Identify the root system specimens: fibrous __, tap __.
- Sketch a root system and label these features: root, root cap, root hairs.
- Vascular System
- Describe the parts of the plant needed for the vascular system.
- Describe the meristematic parts of the plant.
- Define a bud.
- Sketch a woody dicot stem showing the locations of meristem tissue. Label shoot and root apical meristems, lateral meristem (vascular cambium and cork cambium).
- On the woody dicot stem specimen identify two locations of apical meristem: ___ and ___.
- On the log section identify the vascular cambium: _____
1.01b I can relate the parts of a plant to their functions.
- What is the primary function of leaves?
- What are the primary function(s) of stems?
- What are the primary function(s) of roots?
- What are the primary function(s) of the vascular system?
- Compare and contrast the functions of xylem and phloem.
- 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).
- Explain the function of photosynthesis.
- Write the chemical equation for photosynthesis.
- Describe the parts of the plant needed for the photosynthesis system.
- Explain the function of respiration.
- Write the chemical equation for respiration.
- Describe the parts of the plant needed for the respiration system.
- Compare and contrast respiration and photosynthesis.
- Explain two functions of transpiration.
- Describe the parts of the plant needed for the transpiration system.
- Explain the dilemma of plants growing in hot dry regions.
- Explain how sunken stomata, 'hairy' leaves, small leaves and alternative photosynthetic processes such as CAM and C4 are transpirational adaptations.
- Vascular System
- Explain the function of the vascular system.
- Explain how transplant shock is a failure of the vascular system.
- Plant Growth and Development
- Compare and contrast growth and development.
- Compare and contrast primary and secondary plant growth.
- Explain what we mean when we say meristem is capable of differentiation.
- Contrast apical and lateral meristems.
1.03 I can examine and hypothesize about plant variations.
- Describe a leaf structure variation and its adaptive pupose.
- Describe a stem structure variation and its adaptive pupose.
- Describe a root structure variation and its adaptive pupose.
