Prokaryotes

Overview: They?re (Almost) Everywhere! ? Prokaryotes were the earliest organisms on Earth. ? Today, they still dominate the biosphere. ? Their collective biomass outweighs all eukaryotes combined at least tenfold. ? More prokaryotes inhabit a handful of fertile soil or the mouth or skin of a human than the total number of people who have ever lived. ? Prokaryotes are wherever there is life. ? They thrive in habitats that are too cold, too hot, too salty, too acidic, or too alkaline for any eukaryote. ? Prokaryotes have even been discovered in rocks two miles below the surface of the Earth. ? Why have these organisms dominated the biosphere since the origin of life on Earth? ? Prokaryotes display diverse adaptations that allow them to inhabit many environments.

Chapter 26 The Tree of Life An Introduction to Biological Diversity Overview: Changing Life on a Changing Earth Life is a continuum Extending from the earliest organisms to the great variety of species that exist today Geological events that alter environments Change the course of biological evolution Conversely, life changes the planet that it inhabits Figure 26.1 Geologic history and biological history have been episodic Marked by what were in essence revolutions that opened many new ways of life Concept 26.1: Conditions on early Earth made the origin of life possible Most biologists now think that it is at least a credible hypothesis That chemical and physical processes on early Earth produced very simple cells through a sequence of stages

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
Origin of the Cell

Prokaryotes- An organism of the kingdom Monera (or Prokaryotae), comprising the bacteria and cyanobacteria; characterized by the absence of a distinct, membrane-bound nucleus or membrane-bound organelles, and by DNA that is not organized into chromosomes. Spontaneous generation- mistaken idea that life can arise from nonliving materials Biogenesis- Idea that living organisms come only from other living organisms. Protocell- Large, ordered structure, enclosed by a membrane, that carries out some life activities, such as growth and division. Archaebacteria- Chemosynthetic prokaryotes that live in harsh environments, such as deep-sea vents and hot springs The Origin of Life Origins: The Early Ideas Spontaneous generation The idea that nonliving material can produce life
