PPT-Cells organelles

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. Cell theory. Cell organization and homeostasis. Studying cells – microscopy and fractionation. Eukaryotic vs. prokaryotic cells. Compartments in eukaryotic cells (cell regions, organelles). Cytoskeleton. Lesson Objectives:. Describe the structure of an animal and prokaryotic cell. . (AO1: . C). . Starter. RECAP from GCSE. Draw & label a typical . plant. and . animal. cell. Cells. All cells have an internal structure known as the . 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 . 1. . Cell . Theory. All. living things are made of . cells.. Cells are the basic unit of . structure & function.. Cells. come from . pre-existing . cells.. Scientists . Who Formed the Cell Theory. S. 2. , & volume is . S. 3. , where . S. = length of the side of the cube.) Which of the following cube-shaped cells would be most efficient in removing waste by diffusion?. Cells (Test 1). 5. A pathogenic bacterium has been engulfed by a phagocytic cell as part of the nonspecific (innate) immune response. Which of the following illustrations best represents the response?. Cells in animals and plants have unique forms that allow each to take part in processes that are necessary for the cell and or/living thing to survive.. Cells. What is an organelle?. Organelles are to cells what organs are to the body. . 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 (. Cell Parts. Cells. – the basic unit of life. . Organelles. - small structures inside a cell with specific functions.. Analogy – City of Rocklin. Cell . Membrane/Plasma Membrane . Analogy – Rocklin city limits. 1. 2. Peroxisomes. Peroxisomes. = Membrane-bound organelles that contain specialized teams of . enzymes . for . specific metabolic pathways; all contain . peroxide-producing . oxidases. .. • Bound by a single membrane. through cell division. Cells are currently divided into two typ (Before a nucleus): Does not contain a nucleus surrounded by a nuclear membrane or envelope. Contains one or more loops of covalently- Much larger than prokaryotic cells having two enveloped systems. True cells occurring in plants and animals . Though they have different shape size and physiology but all cells are typically composed of plasma membrane cytoplasm and its organelles i.e. mitochondria, endoplasmic reticulum .
