Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some

Chapter 2 IB Biology 2.1 Cell Theory 2.1.1 Outline the cell theory (2). • All organisms are composed of one or more cells • Cells are the smallest units of life • All cells come from preexisting cells • TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms • Exception: muscle cells- more than 1 nucleus‚ very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single

TREATMENT OPTIONS There is NO cure for sickle cell disease‚ although new stem cell research is promising. Bone marrow transplant is a potential cure‚ however finding a matched sibling donor is difficult. Therefore treatment is primarily focused on management of symptoms and prevention of pain episodes. Hydroxyurea (a chemotherapeutic medication) is the only recognized treatment option for the prevention of vaso-occlusive crisis in SCD. It is a prescribed drug for adult patients

Information: Cell Transport When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires energy? ACTIVE Which CELL PART provides the energy for active transport? MITOCHONDRIA Which
