Biology Lesson Plan Eukaryotes and Prokaryotes

Cytoplasm of eukaryotic cell is partitioned by organelle membranes. Organelles together form the endomembrane system.

4. Describe the test used to detect the presence of each type of biologically important

You may use the lab manual, pre-lab lectures, and credible internet resources, however you may not use your cell bio lab classmates as a resource. You will most likely see this material again on the Final and I highly encourage you to work individually and seek help from myself or your TA. Plagiarism will result in an automatic zero.

Prokaryotic: (single cell)The plasma membrane encloses the cell, regulating the traffic of materials into and out of the cell, and separating its interior from the external environment.

There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life.

Draw a prokaryotic and a eukaryotic cell and list 3 differences between prokaryotes and eukaryotes. Be creative in drawing, but be detailed! (1.5 point)

Four AP Biology classes performed this experiment and the data presented in this report will reflect the averages of said classes. In the later discussion sections, it will become

Well prokaryote is the name given to organisms that are made up from cells that lack a cell nucleus or cells that lack any membrane-encased organelles (a specialized subunit within a cell). In lamens terms, in prokaryotes, the DNA is not bound or held together inside a nucleus. Prokaryotes also only have a single loop DNA. Last but not least prokaryotes are divided into groups or domains but more about that in a minute.

I would like to say thank you to Courtney Cochran, my lab instructor and to the UCSB Biology department for the time taken in order to ensure accurate results. Another round of thanks goes to Emile Laroche, my lab partner who aided me in data collection and procedure.

Prokaryotic Cells All living things are made of cells, and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms, and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (monera, the bacteria) and those of the other four kingdoms (animals, plants, fungi and protoctista), which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryotic means 'pre-nucleus' and eukaryotic means 'true nucleus'.

Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex).
