How to Use These “Cards”•The following slides/cards will provide you with information on cellular features, many of which we describe as organelles.•Read through the following “cards” to learn more about each organelle including its structure, function, and the cell types in which each are found. –After downloading, follow along with your “Cellular Organelle Chart” and fill it in as you go. This chart will be helpful for future reference and study.–You will be responsible for knowing/understanding the information within the cards and the chart at the time of the lecture entitled “The Cell.” •You will also be tested on this information directly beforethis lecture in a homework assignment and on upcoming quizzes and exams.
Some Helpful Information Before you Begin•All cells can be divided into two major cell types:1.Prokaryotic Cells•Contains organisms such as Bacteria and Archaebacteria•Most are single celled organisms•Most contain a cell wall rich in the carbohydrate peptidoglycan•Very simplistic cells with few to no major membranous compartments•DNA is found in a circular configuration2.Eukaryotic Cells•Contains organisms such as Plants, Animals, Fungi, and Protists•Can be single-celled or multicellular organisms.•Highly organized cells with multiple membranous compartments to divide cellular work in both space and time.•DNA is compacted into chromosomes and held in its own membranous compartment: the nucleus.
Some Helpful Information Before you Begin1.Prokaryotic Cells
Some Helpful Information Before you Begin2.Eukaryotic Cells**For the sake of simplicity, at this time we will divide all eukaryotic cells into animal and plant cells.Animal CellsPlant Cells****Plant cells contain many of the same organelles found in animal cells with the addition of those seen here.
Organelle Card Key: Cell Type•Although many are shared, not all organelles are found in all cell types. Use the key below to determine in which cell type each organelle is found.–Prokaryotic Cells–Eukaryotic Animal Cells–Eukaryotic Plant Cells
Cytosol•Substance that resides within the cell’s plasma membrane, but outside of all other cellular organelles and/or compartments.•Jelly-like substance that contains 70% water, but that is thickened with ions, salts, and dissolved polar biomolecules (like enzymes).
