The cell BIOLOGY 11

The cell theory All living things are composed of one or more cells. Cells are the basic unit of structure and function of all living things. Cells only arise from pre-existing cells. Cells are divided into two groups based on their organelle characteristics. These two groups are called Eukaryotes and Prokaryotes.

prokaryotes Do not have a true nucleus or membrane bound organelles. They are the most simple types of living cells. Examples of prokaryotes would be different types of bacteria, such as E. Coli and cyanobacteria. Commonly found in air, water, and soil. http://mwsu-bio101.ning.com/profiles/blogs/2263214:BlogPost:2603

eukaryotes Eukaryotes have a true nucleus and membrane bound organelles. Examples of eukaryotes would be plants, animals, fungi and protists (usually single celled organisms, such as an amoeba.) Can be multicellular or unicellular. http://facstaff.cbu.edu/~seisen/EukaryoticCellStructure.htm

assignment Watch the following video and complete the questions. This is due on Tuesday. *Note: Stop video at 5:25 and allow time to self evaluate, matching the organelle to the correct number. http://www.youtube.com/watch?v=1Z9pqST72is Name one way materials move into cells and why this is. List three types of microscopes used for seeing cells. Create a Venn Diagram for eukaryotic vs. prokaryotic cells. What are chromosomes and where are they found? Where are ribosomes manufactured? What analogy was made using the cytoskeleton. What is apoptosis? What is the centriole important for? Extra resource: http://www.youtube.com/watch?v=Hmwvj9X4GNY
