Paola Quinones Lab 4: Planate & Fungi

I. Introduction

In this lab our aim is to identify and study plants and fungi. We will be identifying unique characteristics of plants and fungi that evolved throughout evolution and point out how they differ from plants. Another purpose is to be able to list the distinction between angiosperm & bryophytes & be able to give examples of each; and finally, be able to identify the structure & function of the reproductive parts of a flower.

II. Methods and Materials

For Procedure 1, we needed to collect 5 plant samples from out transect. To do this, we went to our transect and collected 500g of leaves and a little bit of soil and put it in a Ziploc bag. Then, we took samples for 5 different plants and put them in another Ziploc bag. In Procedure 2, we compared the moss with the stem of the Angiosperm lily by closely observing each of them on a microscope. In Procedure 3, we examined the leaves of the moss using a dissection scope and then examined the cross section of an Angiosperm leaf. After examining the leaves from our transect, we described their shape, size, and arrangement of leaves. In Procedure 4, we examined the moss Polytrichium and identified the male & female gametophytes and sporophytes. We then dissected a lily flower and identified all of its parts. Lastly, we dissected the lab seeds & seeds from our transect, and identified the parts of the lab seeds. In Procedure 5, we observed fungi by examining black bread mold in a petri dish in a dissecting scope. Lastly, on Procedure 6, we set up the Berlese Funnel to collect invertebrates. To do this, we poured 25mL of 50:50 ethanol/water solution to the 50mL conical tube, then we fit a piece of the screening material to the bottom of the funnel & taped the sides so the leaf littler doesn’t fall in the preservative. We put the leaf litter sampler from our transect into the top of the funnel and then put the funnel on a ring stand so that it’s held into the tube with the ethanol; we then parafilmed the base of the funnel and the tube. A lighted 40 watt lamp was placed above the funnel with the bulb 1-2 inches above the leaf litter, covered everything with foil, and left it until the next lab.

III. Results

A fungi sporangium is an enclosure found in fungi where spores are formed. All fungi, plants, and other lineages form sporangium at some point in their life. The sporangium can be single celled or multicellular. It is important because it helps to look for nutrients and reproduction.
