6.05 HONORS Lab Report: Dichotomous Key Directions: Use the Dichotomous Key on my site as you carry out this lab. Read all of the instructions below carefully, and fill out the BLUE portions of this sheet. Objectives: After doing this lab activity, you should be able to: Identify bryophytes, pteridophytes, gymnosperms, and angiosperms. Describe the characteristics and classification of the four main plant divisions. Materials: Four plant samples Dichotomous key (a copy is found in the Module Help column at www.rechanek.com) This lab report Hypothesis: 25% Bryophyta 25% Pteridophyta 25% Gymnosperms 25% Angiosperms Procedure: Read all the instructions for this lab before you begin working!
In young dicot stems and stems (usually the upright, vertical portion of a plant transports substances to and the leaves) that do not increase in thickness, xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem. In vascular plants, the dominant sporophyte has two kind of well-defined conducting tissues. Xylem is specialized to conduct water and dissolved minerals, and phloem is specialized to conduct organic nutrients and hormones.
The two types of traditional resources used in regards to the medicinal uses of the Quinine Tree were written book literature and video interviews/documentaries with the knowledge holders of this region. The written literature includes two books, the first a reference type book on ‘Australian Medicinal Plants’, researched and written solely by Botanists/Herbalists. The second, ‘Bush Food’ written by Jennifer Isaacs, is a detailed record of bush foods and medicines used by aborigines from all regions of
Hybridization- crossing different traits to bring the best of organisms into one. For example crossing disease resistance of one plant with the food-producing capacity of another to produce a superior plant. 3)Cloning is the process of taking a single cell from an adult organism to recreate another genetically identical organism. 4)DNA fingerprinting is developed by molecular biology; it analyzes unique sections made up of a variety of DNA band. DNA fingerprinting is a powerful and crucial tool that can determine a person’s identity.
SUGAR CANE AND BEGONIAS The main sources for the references gathered in this paper are from the book The Botany of Desire by Michel Pollen. The book focuses on the interactions between people and plants. I will explain how the begonia and sugar cane have changed over the years. How our interactions with these plants have changed us and how we changed the plants. "A Brief History of Sugar."

The purpose of this experiment is to figure out why different liquids affect plants differently. To do the following experiment you need to 1. Put one plant in each pot of three pots 2. Label one pot A, one pot B & one pot C 3.
This happens when new organisms colonize an area that has already hosted life as a result of primary succession. One example of secondary succession is evident in the far reaches of the foredune community with the Cottonwood tree. These trees have triangle shaped leaves and can grow up to eighty feet high. Their stems act like roots when buried under the sand, allowing them to thrive in the semi-compacted sand as they grow taller by helping to anchor the tree. In this way, the Cottonwood acts as a precursor in succession for larger trees along with Marram grass due to its role in helping to stabilize the soil.
What did Gregor Mendel contribute to the study of biology and what 7 plant traits did he study? Gregor Mendel was the first person to comprehend some of the most basic principles of genetics, and use his experimental subject a species of garden pea. He looked at 7 characters in his plants such attributes as seed color and texture. In his plants, each of these characters came in two verities or traits, one of them dominant and the other recessive. Flower color or purple or white.
Philip Griebel and August Heissner were the first to produce gnomes in quantity in 1872 (“History Gnomes”). “One of the surviving gnomes from Isham’s garden is on display at the Isham estate and is insured for one million pounds sterling” (“History Garden”). One might ask, what is the purpose of gnomes? Gnomes were to watch over crops and livestock. They were thought to provide protection, “especially of buried treasure and minerals in the ground” (“History Gnomes Love”).
The horticultural society that I will be writing about is the Iroquois society. I will be identifying and describing the kinship system and how that system impacts the way their culture behaves. I will also compare the Iroquois society to my own. The Iroquois people are a horticultural society; they are a food-producing society. (Nowak and Laird, 2010, Sections 4.2) They prepare their land and grow the food for their people, what is known as their kinship.
