Build and features of biological membranes.Programme unit:Cell - a basic unit of life.Range:build, features and functions of biological membranes. Examining of selectivepenetrability of membranes. Osmosis, plasmolysis and deplasmolysis.General aim:Study the features, build and functions of biological membranes. Talking abouttypes of the transport through the membranes.Detailed aims:Student is able to: Name and point on the scheme the components of biological membranes. Name the essential functions of biological membranes. Name the features of biological membranes. Name the differences in the built of biological membranes, plant cells and animal cells. Name the kinds of transport through membranes. Define the motions: osmosis, diffusion, plasmolysis, deplasmolysis. Explain the process of plasmolysis in plant cells. Classify proteins by their build and functions. Explain the meaning of notions: hypotonic solution, hypertonic solution, isotonic solution.Skills.Student:Talks about the build of biological membrane on the basis of a model.Compares kinds of transport through membranes.Recognizes on slides the process of plasmolysis and makes its drawing.Recognizes on the schemes types of transport and characterizes them.Analyzes the arrangement of proteins and lipids in biological membranes.Plans the experiment illustrating the process of plasmolysis.Attitudes.Inquisitiveness in looking for answers to the questions. Responsibilityfor cooperation in the group.
