PPT-Cell Organelles

Cell Organelles Organelle little organ Found only inside eukaryotic cells All the stuff in between the organelles is cytosol Everything in a cell except the nucleus is cytoplasm Cell Membrane. What is Cytoplasm and . How Does it Work. What is Cytoplasm. Cytoplasm is defined as the material that lies within the . cytoplasmic. membrane, or the membrane that surrounds a cell. It contains none of a cell's genetic material, because this is contained in the nucleus. It does, however, contain a lot of water, and the other organelles of the cells. It provides a platform upon which they can operate within the cell. It is made up of . 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. Cell theory. Cell organization and homeostasis. Studying cells – microscopy and fractionation.

Literally means “True nucleus”. Have a nucleus. Complex Cells. Have membrane-bound organelles. By: Tim Yacoub and Lizette Magdaleno . Cytoskeleton Overview. Cytoskeleton is a “network of fibers that extend[s] throughout the cytoplasm,”(113). . It’s three structures: microtubules, microfilaments, and intermediate filaments. 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 Cell Parts.

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 .
