Chapter 27- Bacteria and Archaea Prokaryotes live everywhere and are microscopic Concept 27.1: Structural and functional adaptations contribute to prokaryotic success Earth's first organisms were likely prokaryotes Most unicellular, although some form colonies Between .5-5 micrometers, much smaller than eukaryotic cells(10-100 micrometers) Many shapes Spheres (cocci) Rods (bacilli) Spirals Figure 27.2 Prokaryotic cell has a cell wall, which maintains cell shape, protects the cell, and prevents it from bursting in a hypotonic environment (Eukaryotes have a cell wall made of cellulose or chitin) Capsule- polysaccharide or protein layer that covers prokaryotes

2/27/13 1:16 PM Sisterchromatids ? 2 identical copies of a chromosome/chromatin attached at a centromere. Meiosis 2 divisions called meiosis I and meiosis II. During Meiosis I Crossing over ? exchanges genetic information between homologous chromosomes. Independent assortment ? Line up randomly and separate into daughter cells Both increase genetic diversity in sexual reproduction. During Meiosis II Sisterchromatids divide Final Result 4 cells, haploid genetically different from original cell. Mitosis and Meiosis 2/27/13 1:16 PM 2/27/13 1:16 PM

Chapter 13 Meiosis and Sexual Life Cycles Lecture Outline Overview: Hereditary Similarity and Variation Living organisms are distinguished by their ability to reproduce their own kind. Offspring resemble their parents more than they do less closely related individuals of the same species. The transmission of traits from one generation to the next is called heredity or inheritance. However, offspring differ somewhat from parents and siblings, demonstrating variation. Farmers have bred plants and animals for desired traits for thousands of years, but the mechanisms of heredity and variation eluded biologists until the development of genetics in the 20th century. Genetics is the scientific study of heredity and variation.
