PPT-Cell Structure and Function Chapter 2 Lesson 1: Cells and Life

Cell Structure and Function Chapter 2 Lesson 1 Cells and Life Understanding Cells People didnt always know about cells Too small to be seen without proper tools Robert Hooke English Scientist 300 years ago he built a microscope. This organelle contains DNA and controls the cell. Nucleus. Which scientist said “All animals are made of cells”?. Schwann. This . organelle p. roduces ATP (energy) for the cell. Mitochondria . List the three parts of the cell theory!. OCR AS Biology. Unit 1: Cells, Exchange and Transport. Learning objectives. To understand and discuss the basis of cell theory based upon milestones in cell biology. To carry out practical work on cell size and magnifications using a light microscope. Prison Cell. Cell Structure and Function. Fluorescent . Stained Cell. I. Cell Theory (a relatively young concept). A. All living things are made up of cells. - Life must be separated from its environment to be an “open system”. Essential idea: Eukaryotes have a much more complex cell structure than prokaryotes.. T. he background image . above is an electron micrograph . of . pancreatic exocrine . cells. . It clearly shows the complex structures present in eukaryote cells.. 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 . Essential idea: Eukaryotes have a much more complex cell structure than prokaryotes.. T. he background image . above is an electron micrograph . of . pancreatic exocrine . cells. . It clearly shows the complex structures present in eukaryote cells.. Chapters 2 and 3. Overview. 1. Cells are the basic unit of . structure. and . function. in living things.. 2. The structure of living things is determined by how the cells are arranged. Overview of Cells. a hierarchy of life from cells to ecosystems.. HIERARCHY OF LIFE. HIERARCHY OF LIFE. Cell: smallest functional unit of life. Ex. Heart cell (cardiac muscle cell). Tissue: made of similar cells that have the same function. Surface markers. Structure: Variable, integral proteins or glycolipids in plasma membrane. Function: Identify the cell. Example: MHC complexes, blood groups, antibodies. Septate junctions/tight junctions. The printed out notes are more detailed than these slides, you are expected to read the chapter and your notes - anything is fair game on the test, but the cell chapter is largely review. . Quick: Grab some scratch paper and quickly discuss with your partner what you remember from freshman biology about the cell. . Where is the genetic material in a prokaryotic cell?. In a bacterial DNA loop and there may be one or more plasmid rings.. 2. Where is the genetic material in a eukaryotic cell?. The DNA is in chromosomes enclosed in a nucleus. . Structure. Main component is phospholipids that are arranged in a double layer (. bilayer. ). Has scattered proteins within the phospholipids. Regulate what enters/leaves cell. Function . Nucleus. Structure. Pick up a Cell Rubric and Cell parts Handout. Have your binder open to section 10.4. Begin writing in your planner for the week. . Looking inside the cells. 10.4. How Do the Parts of a Cell Work?. Each kind of cell structure has a different and specialized function within a cell.. Pick up a Cell Rubric and Cell parts Handout. Have your binder open to section 10.4.
