SCIENCE CELL – STRUCTURE AND FUNCTIONS Cell – Structure and Functions Cell as the Basic Unit of Life The cell is the basic structural and functional unit of all living organisms. It is the smallest part of the body of an organism‚ is capable of independent existence and is able to perform the essential functions of life. Discovery of the Cell Robert Hooke observed cork cells under a simple microscope designed by him. He observed compartments resembling honeycombs and each compartment

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

STEM CELLS Where are stem cells sourced from? Stem cells are sourced from three main sources‚ Embryos‚ bone marrow and umbilical cord blood. Each different sources’ Stem Cells are either totipotent‚ pluripotent or multipotent. Refer to Figure 1 Figure 1 Stem Cells can be categorised into their capability of being cultured into a different cell. Embryonic Stem Cells: Are pluripotent cells meaning they can be cultured into most cell types. The Embryonic Cells are sourced from in the internal cell mass

Lab 4: Cell Structures and the Gram Stain Purpose: The purpose of this lab is to familiarize the student with the use of a compound microscope and the Gram Stain test. Students will review a brief video and slides to introduce the compound microscope. Students will also view a video about the Gram Stain procedure and then answer questions related to it. Hypothesis If I look at the slides I will see where the cell wall is and what lies inside it and in the Gram Stain if I watch the video I will

Is Stem Cell Research Ethical? Stem Cell Research Stem Cell testing and research covers many different areas today. These cells are the basic center of where cells of any tissue in the body grow. Stem cells have the ability to grow into many different types of tissue that is why they are so unique. Stem Cells can be grown to replace almost any tissue that has been damaged or destroyed by disease. With so many diseases today that are said to be untreatable or have no cure
