40x (x.s.) Make a sketch of 40x and upload it here with the following structures labeled: periderm, cortex, secondary phloem, secondary xylem, vascular cambium, tracheids, resin ducts, Spring wood, Summer wood

Lab 6- Vascular Plant Structures What are the 4 main tissue types discussed (from the outline on p.127) Know this terminology if asked to locate/identify the following: vascular cylinder, vascular bundle, ground tissue, epidermis, palisade mesophyll, spongy mesophyll, guard cells, stoma, xylem, phloem. Can you determine if a plant is a monocot or dicot just by looking at the pattern of the roots? The pattern of the veins in the leaf? The pattern of the vascular bundles in the stem?

Instructions: MULTIPLE CHOICE Only choose the correct answer from questions 13 to 18 and no need for an explanation.

Instructions: MULTIPLE CHOICE Only choose the correct answer from questions 19 to 24 and no need for an explanation.

Do you think it is necessary that organisms continue to modify and specialize?Why or Why not?

Fill in the blank. Words choice: • bud scales • nodes • apical meristem • axillary buds • internodes • terminal

Label the Monocot Leaf Cross-Section

IDENTIFICATION: Please identify the term being asked from numbers 1 to 10, including the one question below. 1. A waxy substance that covers the epidermis of aerial stems in most vascular plants.2. The kind of stem with both primary and secondary tissues present.3. The kind of stem with buds covered by scales.4. Traces left in the leaf scar containing vascular tissues.5. An embryonic shoot located at the tip of the stem.6. A specialized underground stem that can function for vegetative reproduction.7. The superficial tissue in a woody stem.8. The superficial tissue in herbaceous stems.9. The region of the stem where buds and leaves arise.10. What part of the epidermal tissue in herbaceous stem is likened to the lenticel?   QUESTION: 1. Compare the internal anatomy of stems of xerophytes, mesophytes and hydrophytes. Relate differences to the nature/habit of the different plants.

Compare the preserved untreated Allium cepa roots and colchicine-treated Allium cepa roots based on size, appearance and other morphological characteristics.

a. Explain why most dicots have woody stems and most monocots have herbaceous stems. b. Are the monocotyledonous bamboos woody?
