Plant Structure and Function Questions
After reading the Kew B3 Structures sheet and Idaho Master Gardener Program Handbook Chapter 3 Basic Botany, answer these questions:
- What is the primary function of the leaf?
- Write the chemical equation for photosynthesis.
- Compare and contrast respiration and photosynthesis.
- What are two functions of transpiration?
- Where does transpiration get its water?
- Drawing: Sketch a leaf and stem showing leaf, petiole, blade and stipule.
- Drawing: Sketch the following pattern of leaf attachments: alternate, opposite, whorled.
- Drawing: Get a leaf from outside. Sketch the leaf, then use the Figure 2 Terminology of Leaf Characteristics in Chapter 3 Basic Botany to describe the leaf and label your drawing. You will have five descriptors for the leaf.
- What are the two primary functions of the stem?
- What three structures might you find at a node?
- Describe the stem's vascular system.
- Compare and contrast xylem and phloem.
- Why is a woody dicot's vascular system described as continuous?
- Describe the bundles of a monocot stem's vascular system.
- Do you think that a leaf might have vascular bundles? Explain your answer.
- Drawing: Sketch and label a stem with these features: axial bud, internode, leaf scar, leaf, node, terminal bud. Name the plant.
- Drawing: Using a microscope, draw and label a cross-sectional view of a dicot and monocot stem. Name the plants, whether monocot or dicot and identify the vascular bundles. Include a detail of a vascular bundle with the phloem and xylem labeled.
- What are the three primary functions of the roots?
- What percentage of a plant is contained in the roots?
- Describe the two root systems.
- Explain transplant shock.
- Drawing: Sketch a root systems with these features: root, root cap, root hairs.
- Define a bud.
- Buds may be described by their location and by their 'fate'. Name and describe the types of buds.
- Explain what we mean when we say meristem is capable of differentiation.
- Contrast the shoot and root meristems.
- Describe two lateral meristems .
- Why are lateral meristems needed by the plant?
- Compare and contrast apical meristem and intercalary meristem.
- Why is intercalary meristem a good adaptation for plants eaten by animals?
- Why are the trunks of some trees protected from rabbits by fencing?
