The structure shown in micrograph A. Concept introduction: Vascular plants consist of two specialized tissues called as xylem and phloem that act as a conducting tube in plants for the transportation of water and sugar molecules throughout the plant. Xylem is a vascular tissue involved in the transportation of water and minerals from the root to the leaves of plants. It also provides mechanical support and storage to the plants. Xylem consists of two types of conducting cells namely tracheids and vessel elements. Both cells are together called as tracheary element.

Question

As part of an experiment you are required to observe the external features of a fern. State what microscope would you use and give reasons why? You have been provided with a plant showing the rooting system and the stem with several leaves. Give SIX features that you will look for to determine whether this is a monocotyledonous plant or a dicotyledonous plant. Present your answer in a clear, logical manner. In an experiment students were given the following materials and apparatus: - juices from three local fruits; 4% glucose solution; Benedict's solution; test tubes, beakers, syringes and boiling water bath. Describe CLEARLY the procedure that can be used to estimate the amount of glucos present in each juice. Use numbered steps in your answer.

While exploring a forest, you come upon a plant that you haven't seen before. You dig it up and take it back to your lab for further inspection. Back at the lab, you observe the characteristic structure of the plant and make some notes. Then, you carefully dissect the stems and leaves and look at the tissue under the microscope. Finally, you are able to determine the type of plant it is. Use the notes below to identify the class to which this plant belongs. Notes on physical characteristics of the specimen: the plant has no leaves or roots, but has hair-like rhizomes which anchors it in the soil the stems are highly branched sporangia are present at the ends of each stem dissection of the stem shows the presence of vascular tissue in the form of a xylem and phloem

Look at As shown. Part (A) shows the lower half of a fusiform initial (actually most fusiform initials would be much taller than this), and part (B) shows the same cell after it has divided and one of the daughter cells is developing into a xylem cell. Did the fusiform initial divide with a periclinal wall or an anticlinal wall as it went from part a to part b? Part (D) shows that the same fusiform initial has now produced a second cell that is developing into a phloem cell. Was that phloem cell produced by a periclinal or an anticlinal division of the fusiform initial? Part (F) shows the fusiform initial dividing and forming a second fusiform initial. Is this division occurring by a periclinal wall or an anticlinal wall?
