Introduction- Throughout the history of man kind one question has been constantly ASKED and never seems to get a definite answer. The question is who are we? And where do we come from? Rather then spark a religious verse science debate and draw a very emotional line in society we let everyone believe what they want to believe. However regardless of what you want to believe facts are facts and science is science. After going through the Diversity one, two and three labs many things became evident that were somewhat unclear before. One of these things is that we , as man may argue about where we came form and when we got here but we are mere children in the history of planet earth and mere infants in the life that has existed here. The goal of this lab was to understand and be familiar with the millions of organisims that live on earth everday and hiow they got here. The goal was to understand how certain species died out, how they evolved to survive and how organisims have managed to make it millions of years on this planet. This lab takes a look at the three domains Bacteria, Archea, and Eukarya, which contain animals, protists, fungi, bacteria, and plants. And after our observations from the lab me and mark grey my partner concluded many concrete facts about life, evolution, traits and survival.
Observations- Throughout the lad we viewed many different organisims and many different traits. This lab takes a look at the three domains Bacteria, Archea, and Eukarya, which contain animals, protists, fungi, bacteria, and plants. And throughout the lab we uncovered what makes each plant different and what makes each animal in a set kingdom different. The results of our observations were recorded and analyzed from the results that follow. Observations of species and their traits that came from either divergent or convergent evolution were recorded and analysis of each kingdom of species in the lab is included. At the end of the lab mark grey and I concluded that no matter how many observations we collect the world is full of diverse species that live by their own means to survive in a diverse, hostile forever changing world.
Laboratory 3 Diversity I Prokaryotes, Protista, Fungi
Prokaryotes- Prokaryotes are single celled organism without a nucleus or the membrane bound organelles. They are the most ancient lineage of living organisms and exist in Archaea and Bacteria.
The first type of prokaryotes we will explore is bacteria. About 10% of bacteria cause disease, while a large part of bacteria plays important roles in the ecosystem as decomposers. There are three types of bacterial cells: coccus, bacillus, and spirillium all of which we observed in our first stage of the lab. We also observed many different bacterias take on many different shapes. We also looked at
Archaea and Cyanobacteria– Photosynthetic prokarayotes are cyanobacteria or blue – green algae. Species that were observed under the microscope were Amoeba, Woox, Euglena.. These bacteria tend to live in water and be able to process their own food.
After we observed and analyzed the Kingdom Protista- The Kingdom Protista contains two types of organisms unicellular animal-like organisms (the protozoa) and algae. Although most algae are unicellular some are multicellular. As we begin to focus on details and differences between the protistas we begin to notice how higher life forms have evolved. During the lab Mark and I viewed the “volvocine series” Chlamydomonas, Pandorina and Volvox and noticed and reflected on many ideas. We noticed how things can evolve from From Single celled organisms all the way to a cluster of identical cells to a large group of cells which have certain fucntions and purposes. These functions and purposes are designed to save energy and make life and homeostasis less intense.
