0 1 Introduction: Evolution and the Foundations of Biology Overview: Inquiring About Life An organism?s adaptations to its environment are the result of evolution For example, a beach mouse?s light, dappled fur acts as camouflage, allowing the mouse to blend into its surroundings Inland mice of the same species are darker in color, matching their surroundings Evolution is the process of change that has transformed life on Earth Figure 1.1 Figure 1.2 Biology is the scientific study of life Biologists ask questions such as How does a single cell develop into an organism? How does the human mind work? How do different forms of life in a forest interact? Concept 1.1: Studying the diverse forms of life reveals common themes

Name_________________________________Date_______________________Pd._____ Cell Review Worksheet Complete the following table by writing the name of the cell part or organelle in the right hand column that matches the structure/function in the left hand column. A cell part may be used more than once. Structure/Function Cell part 1. Stores material within the cell 2. Digests excess or worn-out cell parts, food particles and invading viruses or bacteria 3. Site of protein synthesis 4. Jelly-like substance in the cell 5. Organelle that manages or controls all the cell functions in a eukaryotic cell 6. Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color

Similarities and Differences Found in Bacteria, Animal, and Plant Cells ? Lesson 3 Assignment Cells are the smallest unit of life. There are two categories of cells, prokaryotic and eukaryotic. Prokaryotic cells contain no nucleus or organelles. Bacteria and archaea are prokaryotic cells. Eukaryotic cells have a nucleus and separate compartments known as organelles. Cells for plants and animals are eukaryotic. Though animals, plants and bacteria are very different organisms and their cellular structures contain differences, they also have some similarities. The easiest way to show this is through the use of a Venn Diagram: http://www.uic.edu/classes/bios/bios100/lecturesf04am/lect06.htm http://www.ivyroses.com/Biology/Cells/Plant-Animal-and-Bacterial-Cells.php

A. Yes B. No 4 http://news.nationalgeographic.com/news/ 2013/11/131129-little-red-riding-hood-folktale- tehrani-anthropology-science/ Where did the story come from? 5 6 7 Phylogenetic analyses are also important for conservation 8 9 Our idea of the tree of life has changed over the years 10 Ernst Haeckel(1866) https://en.wikipedia.org/wiki/Tree_of_life_(biology) We currently recognize

The Endomembrane system Organelle recap? Ribosomes Ribosomes: a complex of ribosomal RNA (rRNA, synthesised in the nucleolus) and proteins Ribosomes carry out protein synthesis in: The cystol/plasm (free ribosomes) On the outside of the rough endoplasmic reticulum Free ribosomes make proteins used within the cell e.g. enzymes Bound ribosomes make proteins which are often secreted e.g insulin made in pancreatic cells Endoplasmic reticulum Form Accounts for more than half of the total membrane in many eukaryotic cells The ER membrane is continuous with the nuclear envelope There are two distinct regions of ER: Smooth ER: lacks ribosomes Rough ER: ribosomes are bound to the outer membrane Functions: Smooth endoplasmic reticulum

Chapter 24 Early Life and the Diversification of Prokaryotes Overview: The First cells Chemical and physical processes on early Earth may have produced very simple cells through a sequence of stages: 1. Abiotic synthesis of small organic molecules 2. Joining of these small molecules into macromolecules 3. Packaging of molecules into protocells 4. Origin of self-replicating molecules Synthesis of Organic Compounds on Early Earth ? Earth formed about 4.6 billion years ago, along with the rest of the solar system ? Bombardment of Earth by rocks and ice likely vaporized water and prevented seas from forming before 4.2 to 3.9 billion years ago ? Earth?s early atmosphere likely contained water vapor and chemicals released by volcanic eruptions

Chapter 6 A Tour of the Cell Concept 6.2: Eukaryotic cells have internal membranes that compartmentalize their functions two types of cells make up all organisms?prokaryotic and eukaryotic only domains Bacteria and Archaea consist of prokaryotes Comparing Prokaryotic and Eukaryotic Cells bounded by a membrane?plasma membrane within the membrane is a semifluid. cytosol, in which organelles are found all contain chromosomes and ribosomes Prokaryotic Cells no nucleus; DNA is concentrated in a region called the nucleoid, but no membrane separates this region from the rest of the cell Eukaryotic Cells have a true nucleus, bounded by a membranous nuclear envelope entire region between the nucleus and plasma membrane is the cytoplasm

Mica Piro Chapter 6: A Tour of the Cell Biologists Use Microscopes and the Tools of Biochemistry to Study Cells (6.1) Microscopy Microscopes first used by Renaissance scientists are all light microscopes (LM) Visible light passed through the specimen and then through glass lenses Lenses refract/bend the light so the image of the specimen is magnified as it is projected into the eye or into a camera Magnification: ratio of an object?s image size to its real size LMs can magnify about 1,000 times the actual size Higher magnification = less detailed image Resolution: a measure of the clarity of the image?minimum distance 2 points can be separated and still be distinguished as separate points Contrast: the difference in brightness between the light and dark areas of an image
