General-> specific, single cell-> all body cells 2. Amoeba sp, monocytes, & neutrophils Developmental Aspects of Cells 1. Vesicle formation & movement into the cell 4.
Formation of cytoplasmic extensions, pseudopodia 2. Vesicle formation & movement of material into the cell Phagocytosis 1. Active transport, exocytosis, endocytosis Endocytosis 1. Movement of molecules into cell against a gradient 2. Usually water-soluble molecules Energy Negative 1. Diffusion assisted by transport proteins 2. Crenation- the shrinking of cells in a hypertonic solution, especially RBCs Facilitated diffusion 1. Plasmolysis- plant cell’s plasma membrane pulling away from its cell wall as the central vacuole loses H2O 2. Hypertonic Isotonic Hypotonic Hypertonic 1. Ions across cell membrane through channel proteins Tonicity 1. Dissolved gases (O2 & CO2) & lipid soluble molecules across cell membrane 3. Net random movement of a substance from areas of greater concentration to areas of lesser concentration 2.
Diffusion, osmosis, & facilitated diffusion Diffusion 1. Movement with a concentration, electrical, or pressure gradient 2.
Energy neutral & energy negative Energy Neutral 1. Movement of materials in & out of the cell 2. Embedded proteins shift through the bilayer Phospholipid BilayerĬell Transport 1. Plasma membrane is a phospholipid bilayer with embedded proteins, cholesterol, glycolipids, & glycoproteins 3. Local mesh refinement controls can resolve geometry details appropriately, and poor CAD models can be improved in SpaceClaim/Discovery, or you can use Fluent's Fault Tolerant meshing workflow, which is robust to CAD faults.Download Fluid Mosaic Model - Lecture Slides | BIO 1040 and more Biology Study notes in PDF only on Docsity!Fluid Mosaic Model 1. Poor mesh quality can also be caused by insufficient mesh resolution of geometry details or by poor underlying CAD. When selected, you will then enter the percentage of the total cells to be improved, and the number of iterations of smoothing sweeps performed. If you are in Fluent Solution mode, you can improve the mesh quality by selecting the improve the mesh option on the Quality button under the Domain tab. To improve the surface mesh, you will have to enter a face quality limit to target, and when improving the volume mesh, you will have to enter a cell quality limit value to target. If you are still in the process of generating your mesh in Fluent Meshing mode, you can insert a task after both the 'Generate the Surface Mesh' task and 'Generate the Volume Mesh' task by right-clicking on either one and inserting a new 'Improve Mesh' task. Mesh quality can be improved in a variety of places in Ansys Fluent.
