PPT-Nucleus & Nucleolus

By Dan Intartaglio amp Joel Skivington History Robert Brown 17731858 Discovered in 1831 by Scottish botanist Robert Brown Suggested the nucleus played a key role in fertilization and development of the embryo in plants. By Charles Taylor and. Weston Gray. Mr. Burton's Class. Introduction. Typically when you make a PowerPoint, you start out with something boring that stops whoever is reading it to stop paying attention. I don’t believe in that.. Reece . Andonov. Lizzie . Codina. Period 3. Nucleus . vs. Prison Warden. Found in both types of eukaryotic cells. The nucleus is like the prison warden because the warden controls all aspects of the prison and the nucleus controls all functions of the cell, also they are both the most important.. Plasma membrane, nucleus and ribosomes. Figure 4.7a. CYTOSKELETON:. NUCLEUS. ENDOPLASMIC RETICULUM (ER). Smooth ER. Rough ER. Flagellum. Centrosome. Microfilaments. Intermediate. filaments. Microvilli. Plasma membrane, nucleus and ribosomes. What to Know . The structure and function of the plasma membrane, nucleus and ribosomes.. Figure 4.5. 0.1 . . m. (a) TEM of a plasma. membrane. Outside of cell. Objective 34: I can describe the shape of an animal and plant cell.. Animal cells: are roundish shaped. Plant cells: are rectangular shaped. Objective 35: I can describe plant and animal cell organelles. Kelly . Bushouse. , Cap Kelly, and Connor O’Neill. What is the nucleus?. . The nucleus is the control center of the cell.. Hereditary information is stored as DNA and RNA in the nucleus.. The nucleus controls reproduction, movement, eating, and more.. Types of Cells. Prokaryotic cells. Eukaryotic cells. Prokaryotic cells. Simplest cells. No membranes around their nuclear material (DNA and RNA, genetic material). Prokaryotes include bacteria and some pond scum. Some History of the Nucleus. Was discovered by Ernest Rutherford, a New Zealand born British physicist, in May of 1911.. In . a well-known experiment done by one of Rutherford's students, . alpha particles were observed to scatter backwards from a gold foil. Rutherford’s . How are Organelle and analogous parts similar?. Example today: The New England Patriots!. Cytoplasm. Cytoplasm Cushions the inside of the cell.. Just like the cytoplasm cushioning the inside of the cell your running back provides cushion that you should always be able to rely on your running back..
