PPT-Membrane Function and Cell Communication

Summary How do materials get across a cells membrane It depends on the type of substance Summary Nonpolar materials or hydrophobic materials do cross easily especially if small Ex CO. VOCABULARY. directions: mark each term to indicate if you know it, are unsure, or don’t.. amplify . communication. deleterious elaborate. embryology evolution . fluid . mosaic model mechanism. 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. Key Points:. Structure (and importance) of . cell membrane. Structure (and function) of . organelles. Interconnections between cells. . to maintain structural stability in body tissues.. A . typical cell. 1. (Ch. 6). Dead White Men Who Discovered (and were made of) . Cells:. Anton Van . Leeuwenhoek. Robert. Hooke. Where the Magic Happened. Microscopy is certainly a Perspective Changer (sorry . in advance). Section 7.1 Summary – pages 171-174. The . cell theory. . is made up of three main ideas:. All cells come from preexisting cells.. The cell is the basic unit of organization of organisms.. Structures, Functions and Organelle Relationships. p.50-50 in textbook. Animal Cell. Plant Cell. Cell Membrane & Cell wall. The cell membrane (plasma membrane) creates a cell boundary and helps to regulate the transport of molecules in and out of the cell (in plant & animal cells).

You may want to make flashcards and save the flashcards for your final exam. CHROMOSOME AND CELL DIVISION Despite the diversity among cells, three basic features are common to all cell types. All cells have outer boundary, an interior substance and a control region. CELL STRUCTURE AND FUNCTION Structure. Main component is phospholipids that are arranged in a double layer (. bilayer. ).
