until next week. When we came in next week we observed our fern spores through the dissecting microscope. We looked to see if we could find anything germinating. We quickly noticed something that appeared like an air bubble squirting out something green. This was our fern spore which was germinating. Next‚ we removed a few of the germinating spores from the petri dish and put them under a compound microscope scope. We found the spore wall and observed how the developing gametophyte had broken through

Observing Cells Objectives: After completing this exercise and reading the corresponding material in your text‚ you should be able to 1. Prepare a wet mount slide 2. Identify structures described in this lab on slides 3. Cite examples of the wide diversity of cell types 4. Relate differences in structure among cells to functional differences Introduction Structurally and functionally‚ all living things share one common feature: all living organisms are composed of cells

support: Spontaneous generation theory: Frogs come from muddy soil because they always appear in that environment. Flies come from rotten meat because they always appear where meat is rotting. Cell theory: Without the invention of the microscope‚ the cell theory would not have been possible. All living things are made up of cells. Provide evidence for or against the statement you chose. Include proper APA citation of outside sources if applicable. Read another student’s post and

Purpose: To observe epithelial tissue by using a microscope to compare prepared slides. Introduction: Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as
