VASCULAR TISSUES
The xylem and phloem that makc up they ascular tissues arc present in seedless vascular plants, as well as in gymnosperms and angiospemu.
Observe a sagittal section of a stcm of a gymnosperm and an angiosperm. Recognize the xylem and phloem cells. Use the information provided next to the specimen and lathe resource binder to answer the following question:
List the features that you were able to identifr as part of the xylem and phloem.
Observe a cross section of a stem of a dicot and a monocot plant. Identify the vascular bundles that contains the xylem and phloem. Draw the arrangements of these vascular bundles for each plant (Use the 4X objective lens). Label the structures observed.
Alonocot Distal What does the xylem transport? is the xylem a living tissue? What does the phloem transport? Es’ the phloem a living tissue? What tissue make up the wood? What tissue makes up the bark?
SEEDS
Gymnosperms were the first group of plants to produce seeds, an important novelty trait in the evolution of plants that help them to become successfid and a dominant group by the time of the dinosaurs.
