a type of biological diversity that is exhibited in the variety of structural forms in living things‚ from internal cell structure to body morphology. ➢ Prokaryotic: a smaller‚ simple type of cell that does not have a membrane-bound nucleus. ➢ Eukaryotic: a larger complex type of cell that does have a membrane-bound nucleus. ➢ Dichotomous key: an identification tool consisting of a series of two-part choices that lead the user to a correct

rumination more often. . Response Style Theory ( RST) propose that women are more prone to rumination when in a depressed mood‚ and that men will more often use reflection in response to their depressed moods (Nolen-Hoeksema‚ Larson & Greyson 1999). It has been proposed by ’Kuehner & Webber.‚ (1987‚ 1990‚1991 as cited in Nolen-Hoeksema et al.‚ 1999) ’ that RST has two main emotion focused coping

of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some of the earliest forms of life. In this chapter‚ we will learn how bacterial groups are differentiated from each other and how important bacteria are in the world of microbiology

Microorganisms and Fungi Bacteria and Viruses Viruses Vocabulary virus: A nonliving‚ infectious particle composed of a nucleic acid and a protein coat; it can invade and destroy a cell. pathogen: A virus‚ microorganism‚ or other substance that causes disease; an infectious agent. capsid: A protein sheath that surrounds the nucleic acid core in a virus. envelope: A membrane-like layer that covers the capsids of some viruses. glycoprotein: A protein to which carbohydrate

History of microorganisms’ discovery Anton van Leeuwenhoek was the one of the first people to observe microorganisms‚ and used a microscope of his own design‚ and made one of the most important contributions to biology. [18] Robert Hooke was the first to use a microscope to observe living things; his 1665 book Micrographia contained descriptions of plant cells. Before Leeuwenhoek’s discovery of microorganisms in 1675‚ it had been a mystery why grapes could be turned into wine‚ milk into cheese

Protists Protists are a very large‚ diverse group of organisms‚ including the plant-like protists (algae)‚ fungi-like protists‚ and the animal-like protists (protozoans). They are all eukaryotic‚ and most are unicellular. Traditional taxonomy of protists (Kingdom Protista) did not accurately represent evolutionary relationships‚ so the classification of this group is unsettled. Modern taxonomy has rearranged the group formerly known as Kingdom Protista‚ separating the different types of organisms

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

A virus is not a cell A virus is an infectious agent that contains either DNA or RNA surrounded by a protein coat. Prokaryotic (Eubacteria‚ Archebacteria) Eukaryotic (Plant‚ Animal‚ Fungi‚ Protists) Prokaryotes are the most diverse of cells EXTREMOPHILES- live in very inhospitable environments.
