Cell Organelles and Features: Transcript


PlasmaCell Membrane Found in both prokaryotes and eukaryotes Structure Composed of phospholipids cholesterol and proteins Organization Phospholipids form a bilayer Proteins and cholesterol are embedded in the bilayer. 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. Eukaryotic vs. prokaryotic cells. Compartments in eukaryotic cells (cell regions, organelles). Cytoskeleton. Lesson Objectives:. Describe the structure of an animal and prokaryotic cell. . (AO1: .
