THE HERBARIUM PROJECTIntroduction:In some countries, people have used nature to decorate living spaces. This is the case for plants, in which leaves, barks, flowers and fruits have been used for this purpose.

This stylish idea has come from what botanists do to store the plants that they have collected during their expeditions. A herbarium is a place where you can find a sample of the countries´ plant diversity. Is home for the duplicates of all the plants that were collected in the country. There are herbariums in every country and are a sanctuary that can speak of no longer existing genera or species.

In this opportunity, to conclude our plant studies, we will rememorize what botanists do by classifying plant samples and preserving them for the future.

Objective: Classify plants according to their physical characteristics using the scientific terminology that applies.

Summary:For the completion of this unit, you, along with your two other classmates are going to present a project. This project consist of presenting 6 samples of plants belonging to 3 different phyla (2 per phylum) with a taxonomic key to differentiate them.

Due date: A: 2:00pm of November 17th, 2016B: 7:00am of November 18th, 2016

Methodology: 1. Decide what phyla you are going to work with. Note: If you choose Anthophyta, your flowering plant must be

different from any other between the two classes.

2. Create a timeline with the events and tasks. Deliver it to the teacher before the end of the class.

3. Collect the samples, record the information of the collecting site, dry the samples and bring them for some class to do the mounting process. When collecting the sample, you should have special care of

taking notes of a) the date you collected itb) the place (country, province, hill or even neighborhood)c) the habitat where you collected the plant (water, soil, over

rock or concrete, trunk, decomposed log).c) any characteristic that you think may vanish after the drying

process (color, humidity, latex or “milk” of the stem)d) persons who were collecting with you.

4. Create the packets (Figure 1) and labels (Figure 1 and 2B) with the collected information for each sample. You should look for the common name of the plant, and then for the scientific (ONLY FAMILY, GENUS OR SPECIES will be accepted).

5. Store the plants in the packets or mount them, whatever it applies. For mounting all the seedless vascular or seed plants, you will need (cartoncillo) of 35 x 25 cm. Ask the teacher to help you paste the sample in the sheet of paper. Bring glue. For seedless and non-vascular plants, the mounting should be like Figure 2A-B; for all the other, like 2C.

6. Meanwhile, choose the characteristics of the samples you collected and sort them to create your dichotomous key. Be sure to include the a) Plant´s lifespan type, if it applies. b) If it is to have cotyledons, how many does it hasc) Spore or seed dispersal type

It must be done in computer. Remember to follow all the scientific grammar rules.

For the completion of these project, you will be provided with 3 class hours. 11th A: Tuesday 15th and Wednesday 16th. 11th B: Tuesday 15th and Thursday 18th.

Frontal part of the packet, which has the label that describes major features of the plant and collecting environment. 2C. Sample of how seedless vascular plants and seed plants are mounted. In this case, a sample of the fruit has been stored in a packet. Pay attention to the label, which has the same items as the one for seedless non-vascular.
