PPT-3 : Organelles and their structures

Lesson Objectives Describe the structure of an animal and prokaryotic cell AO1 C Starter RECAP from GCSE Draw amp label a typical plant and animal cell Cells All cells have an internal structure known as the . Parts of the plant and animal cell. Organelles. I look like hairs that trap anything trying to come into the cell? Who am . i. ?. Cilia. organelles. I am a framework for the cell. I have many functions one of which is intracellular. organelles which with fluid, and periodically expelling contents from once every expulsion can be modified by external factors, particularly osmotic pressure bathing medium. more adequately described Both are chemically similar in that they contain nucleic acids, proteins, lipids, and carbohydrates. They use the same sort of chemical reactions to . metabolise. food, build proteins and store energy. Electron Microscopy. Because these electron micrograph (EM) images are very detailed, you should view this demonstration in the Slide Show view. Click the Slide Show tab, then select From Beginning (or for the true geek, the little projector icon in the lower right). After that, your up/down arrows will advance or retreat the demonstration.. Organelles do the work of cells. each structure has a job to do. keeps the cell alive; keeps you alive. Model Animal Cell. 1. Cells need power. !. Making energy. to fuel daily life & growth, the cell must…. Before we begin, . what are . organelles. ?. Cells organelles. If we have “organs”, cells have …. Organelles: Specialized parts of the cell . . . . with specific functions. Cells organelles. Agenda for Wednesday Feb 22. nd. . Finish macromolecules. Cells. Cell Theory . Anton van . Leewenhoek. Created a microscope. Saw living things in milk, pond water, etc. Matthias . Schlieden. Looked at plants and concluded they were composed of cells. but also found free in the cytoplasm . Site of protein synthesis. Not membrane bound. A large protein subunit and a small . ribosomal RNA (rRNA) subunit form the . functional ribosome . Subunits bind with mRNA (copy of gene) in . Atom . Molecule. Organelle. Cell. Tissue. Organ. Organ System. Organism. Division of Cells. Eukaryotic Cells. Literally means “True nucleus”. Have a nucleus. Complex Cells. Have membrane-bound organelles. Organelles that Store, Clean up, and Support Organelles that store, clean up, and support Vacuoles, Vesicles, Lysosomes , and the Cytoskeleton Vacuoles are large saclike structures that store materials like Cell Theory • living things contain empty room - like compartments that he called “ cells ”. • In 1864, Louis Pasteur proved that new living things can come only from other living things of . . U.N.NAZNIN. 1. . The Fundamental Unit of Life- CELL. . . A . cell is the structural and fundamental unit of life. . . All organisms are made up of cells. They may be made up of a single cell (unicellular), or many cells (. The ultrastructure of eukaryotic cells. Spec. Animal Cell Plant Cell. Starter. In pairs - Identify the main similarities and differences between animal and plant cells. Animals vs. Plants.
