PPT-Prokaryotic Cell Structure & Function

How are Prokaryotes Different from Eukaryotes The way their DNA is packaged No nucleus Not wrapped around histones The makeup of their cell wall Bacteria peptidoglycan Archae tough and made of other chemicals distinct to them. Prokaryotic vs. Eukaryotic Cells. Two Basic Types. Remember….cells are the basic unit of life for ALL living things.. There are two basic types of cells:. Prokaryotic cells . – found in bacteria. Note that the ATG codon encodes both start and methionine . Prokaryotic genes have a simple one-dimensional structure. 5’→. ←. 5’. 5’→. ←. 5’. Start codon. Stop codon. ATG. TAG. ATG. AAA. Cell theory. Cell organization and homeostasis. Studying cells – microscopy and fractionation. Eukaryotic vs. prokaryotic cells. Compartments in eukaryotic cells (cell regions, organelles). Cytoskeleton. Eukaryotes, Prokaryotes and Measuring Cells. Lesson Objectives. To understand the difference between eukaryotic and prokaryotic cells.. To describe the features of a prokaryotic cell such as a bacterium.. Introduction to Biochemical Principles. Chapter 2. Living Cells. Section 2.1: Basic Themes. The cell is a molecular machine and the basic unit of life.. Cells are molecular factories:. Respond to their environment. Eukaryotes, Prokaryotes and Measuring Cells. Lesson Objectives. To understand the difference between eukaryotic and prokaryotic cells.. To describe the features of a prokaryotic cell such as a bacterium.. PROKARYOTES. EUKARYOTES. CYTOPLASM. Cell Membrane. DNA. Always single-celled. No Nucleus. DNA is a simple,. Single loop. Small Cells. (1 – 10 . um. ). Bacteria. . Can be single- or multicellular . TSW – Recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. 6.12B. Cells. There are two . basic types . of cells. Prokaryotes. or prokaryotic cells . Eukaryotes. Cell/Developmental Biology I. Group Members. Kelly Hogan, Facilitator . Rita Graze. Matthew . Kearley. . Zheng-Hua. Ye. Xiaoyu. Zhang. Christine Sestero. Heather Tinsley. Learning Goal: . Understand . Endosymbiosis. h. eterotrophic eukaryote. Examine these diagrams showing . how an ancestor to eukaryotic cells may have engulfed smaller heterotrophic prokaryotic cells that began producing ATP for it. 21.4 Prokaryotes—Enduring, . Abundant, and Diverse. Prokaryotes. Structurally simple cells that lack a nucleus. Evolved before eukaryotes . Abundance and Metabolic Diversity. Prokaryotes are Earth’s most abundant organisms. CHAPTER 27. PROKARYOTIC ADAPTATIONS. typical prokaryote:. 0.5 -5 microns. unicellular. variety of shapes. cocci. (spherical). bacilli (rods). spirochetes (corkscrews).
