Chapter 5: Membrane Transport and Cell Signaling Amphiphatic- refers to something that has both hydrophilic and hydrophobic regions the cell membrane proteins Fluidity Low Temperatures-less fluid because the phospholipids pack together tightly Factors that Affect Fluidity: Amount of phospholipids- phospholipids have kinks in the tails due to their hydrogen bonds which make them harder to pack Cholesterol- inhibits the packing of the phospholipid tails at LOW TEMPERATURE. AT HIGH TEMPERATURE, it solidifies the membrane because it inhibits the movement of tails Proteins in the Membrane Intergal-penetrate the membrane, hydrophobic exterior, hydrophilic interior Peripheral-lie on either side of the membrane Major Protein Functions: -Transport-allows materials to diffuse

Chapter 12 The Cell Cycle and Mitosis The Key Roles of Cell Division Cell division functions in reproduction, growth, and repair Unicellular organisms (ex. Amoeba) will divide to reproduce entire organisms Cell division also will allows a multicellular organism to develop from a single cell The Key Roles of Cell Division DNA is passed from one generation of cells to the next without dilution. -cell duplicates it DNA - moves the 2 copies to opposite ends of the cell - and then splits into 2 daughter cells The Key Roles of Cell Division Concept 12.1 Cell Division distributes identical sets of chromosomes to daughter cells A cell?s genetic material is called its genome - prokaryote = single long DNA strand - eukaryote = number of DNA molecules Concept 12.1

Plant physiology

Maia Regman Mrs. Magnan Biology Honors 28 October 2013 Plant and Animal Cells Objective The objective of this lab was to learn what a microscope reveals about plant and animal cells. The completion of this lab should teach the participant the differences between plant and animal cells and how to examine samples of the covering tissues of a plant (the onion) and of an animal (the participant) using the epidermis and cells from a cheek swab of epithelial tissue. Materials Packet Pages L14 to L16 Onion Chunks Compound Microscope Microscope Slides Covers Slips Water Pipette Lugol?s Iodine Solution Tweezers (optional) Paper Towels Flat Toothpicks Procedures. Part A: Cells of the Onion Epidermis Gently peel off one of the thin layers of the inside of the onion chunk.

Cell Growth and Reproduction Cell Reproduction All cells come from preexisting cells. Cell division results in two cells that are identical to the parent cell. New cells are constantly being produced. Scientists noticed certain structures that appeared just before cell division and disappeared after. Chromosomes: structures which contain DNA and become darkly colored when stained For most of a cell?s life, chromosomes exist as chromatin Chromatin: long strands of DNA wrapped around proteins called histones Histones are grouped in bunches called nucleosomes The Cell Cycle Cell cycle: the sequence of growth and division of a cell Two general periods of the cycle: growth and division The majority of a cell?s life is spent in the growth period known as interphase

Chapter 7 A View of the Cell The Discovery of Cells The History of the Cell Theory The first person to record looking at water under a microscope was Anton van Leeuwenhoek. Robert Hooke used a compound light microscope to study cork, the dead cells of oak bark. Matthias Schleiden studied plants under a microscope and concluded that all plants are made of cells. Theodore Schwann studied animal cells and concluded that all animals are made of cells. Rudolf Virchow hypothesized that cells divide to form new cells & all cells come from preexisting cells The Cell Theory: All organisms are composed of one or more cells. The cell is the basic unit of organization of organisms. All cells come from preexisting cells.

All of the following are part of a prokaryotic cell except a. DNA. b. a cell wall. c. a plasma membrane. d. ribosomes. e. an endoplasmic reticulum. 2. The volume enclosed by the plasma membrane of plant cells is often much larger than the corresponding volume in animal cells. The most reasonable explanation for this observation is that a. plant cells are capable of having a much higher surface-to-volume ratio than animal cells. b. plant cells have a much more highly convoluted (folded) plasma membrane than animal cells. c. plant cells contain a large vacuole that
