Cell Biology- Osmosis‚ Cell Size and Diffusion and Enzymes 1.0 INTRODUCTION Cells are the basic building blocks of all living things. They provide structure for the body‚ take in nutrients from the food‚ convert those nutrients into energy‚ and carry out specialized functions. Cells also contain the body’s genetic material and can make copies of themselves. A cell is also a metabolic compartment where many different chemical reaction occur. There are two types of cells‚ eukaryotic and prokaryotic

ascus. The spores germinate and form hyphae (Campbell‚ 64) Species of the genus Sordaria share a number of characteristics that are advantageous for genetic studies. They all have a short life cycle‚ usually 7-12 days‚ and are easy to grow on nutrient agar in dish cultures. All kinds of mutants are easily induced and readily obtainable with particular ascospore color mutants. These visual mutants aid in tetrad analysis‚ especially in analysis of intragenic recombination. ( Campbell 72) A
