Summary Introduction

To determine:

The way in which a biologist can ascertain the origin of thorns, spines, and tendrils.

Introduction:

Stems and leaves are the vegetative parts of a plant. The tissues that constitute the leaves and stems are dermal, ground, and vascular tissues. Stems provide support to the leaves, which produce carbohydrates such as sucrose by photosynthesis.

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  phylum to which this plant belongs. Notes on physical characteristics of the specimen: the plant has no leaves or roots, but does have hair-like rhizomes which anchored 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
