Basic Woody Plant Biology (Above and Below Ground)

Identify the components of a plant cell and know the functions of each.

What is "mitosis" AND in what 3 locations in a tree does it occur? What is this tissue called?

What type of tissues are formed by the vascular cambium, AND what function do each of these perform?

Identify and describe the functions of each of the components in a woody stem cross-section.

Reaction Wood: In conifers it is called Compression Wood; In broadleafs it is called Tension Wood.

Define "bud". Distinguish between dormant buds, adventitious buds and latent buds.

Distinguish between watersprouts and suckers.

Recognize components in a cross-section of a leaf.

Describe the physiological functions of Photosynthesis and Respiration. What are their chemical formulae?

What is "Translocation"? What is "Transpiration"?

Recognize the components of a tree root AND the functions of each.

Recognize the different types of tree roots and their function. Where is each of them located in relation to the tree and soil surface?

What are the 4 main functions of tree roots?

How are transpiration and absorption related?

How does osmosis influence absorption? What is turgor pressure?

What are Mycorhizae AND what function do they perform?

What are some above ground human-activities that influence root growth and development?

Distinguish between Apical Dominance and Apical Control.

Distinguish between Decurrent and Excurrent tree forms. How do apical dominance and apical control relate to these tree forms?

What is the "mortality spiral"?
