OBJECTIVES: the student will use differently prepared celery stalks to make observations and collect data. The data will provide necessary knowledge to be able to differentiate some basic characteristics associated with plant’s xylem and phloem vascular tissues.
OVERVIEW: Students will be working in small groups that will be assigned by your teacher to observe vascular tissue in plants. The vascular tissue is the transport system made up of two primary specialized tissues: xylem, which carries water from the roots upwards to the leaves as it is needed for photosynthesis, and phloem, which carries glucose/ manufactured food from the leaves to the rest of the plant. Xylem and phloem arrange themselves in vascular bundles. Cutting a cross-section through stem usually shows the vascular tissue bundled together in a stem.
Please see sample for the exact lab report. This lab is super easy to set up and conduct with students. The lab also helps reinforce the idea/concept of xylem and phloem in an engaging hands-on way.
