Q1. How does your chromatogram differ from one that another group did with a different plant? How are they similar? Q2. pigments fluoresce? What colour does each of the fluorescent pigments appear under UV light? Q3. How can you explain the presence of colours on the chromatogram that are absent in the original leaf? Q4. Explain how you would account for the differential rates of migration of the various pigments using specific examples. What is the principle behind the separation? LABORATORY EXERCISE 5: Anatomy Laboratory Exercise 5: Plant Anatomy In this lab you will examine several types of plant tissue under the microscope. Part A: Pre-Lab Quiz Questions. (5 points) Lab 5 Pre-Lab Quiz Questions In your own words, define each of the following terms. Apical bud Axillary bud Collenchyma Cotyledon Ground tissue Meristem Parenchyma Petiole Phloem Sclerenchyma Sclerid Xylem Part B: Lab Protocols. 1) Primary growth and development Plants produce new throughout their lifetime as a result of cell division in meristems. Tissues produced by apical meristems are called primary tissues, and this growth is called primary growth. Primary growth occurs along the plant axis at the shoot and root tip.
