The six kingdoms are grouped according to five major categories in addition to other major characteristics. The categories are:
I. CELL TYPE: (kind of cell) all cells are made of the same organic material) A. PROKARYOTIC: no organized nucleus, no internal membranes, peptidoglycan cell wall, have ribosomes (small), bacteria and blue-green algae B. EUKARYOTIC: organized nucleus, internal membranes, nonpeptidoglycan cell wall
II. CELLULAR ORGANIZATION: A. NUMBER OF CELLS 1. UNICELLULAR: (single-celled) all life functions, solitary or colonial (chains or clumps) 2. MULTICELLULAR: (many-celled) a. hyphae body form b. tissue differentiation (limited to advanced organisms) B. LEVELS OF ORGANIZATION (Tissue Differentiation) 1. cells, 2. tissues, 3. organs, 4. organ

organized structure The complexity of life is built in levels. (see fig 1-1) Each level has ingredients or components which interact to make something greater than the sum of the parts. -Subatomic particles -Atoms -Molecules -Organelles (not present in prokaryotes) -Cells -Tissues (present only in multicellular eukaryotes) -Organs (present only in multicellular eukaryotes) -Organ systems (present only in multicellular eukaryotes) -Multicelled organisms -Populations -Community…
Microorganisms are organisms that are too small to be seen with the unaided eye Germ refers to a rapidly growing cell Microorganisms include: Bacteria, archea, protozoa, fungi, actinomycetes, algae, viruses Atom – Molecule – Cell – Tissue – Organ – Organ System – Organism – Polpulation – Community – Ecosystem – Biosphere Autotrophs – Herbivores – Carnivores – Top Carnivores Microorganisms beneficial roles: - Marine and freshwater microorganisms are at the base of food chains…
I. Section 1: Biodiversity investigates the variety of organisms considered at all levels from populations to ecosystems A. Taxonomy the science of describing, naming, and classifying organisms 1. Taxon any particular group within a taxonomic system 2. Aristotle classified organisms into only two taxa: plants and animals. He grouped animals according to whether they lived on land, water, or air and grouped plants based on differences in their stems. B. The Linnaean System 1. Car…
Dougherty 3/15/2012 Biology Half Sheet 1. Humans are classified like any other organism by their kingdom, phylum, class, order, family, genus, and species. Humans are in the kingdom Animalia. This is because we are heterotrophs and are multicellular. Humans are in the phylum Chordata. This is because we have a backbone. We belong in the class Mammalia because we give milk, have hair all over, and we give birth to offspring. We are in the order Primates because we have and opposable thumb.…
the amount of humans that have ever lived - Bacteria, a type of prokaryote, cause half of all human illnesses, including: plague and cholera, strep throat, ear infections, and STD’s -Pathogens – are bacteria that are disease causing B. Bacteria and Archaea - Prokaryotes lack a nucleus and other membrane enclosed organelles - There are now two types of Prokaryotes, Bacteria and Archaea, after they realized bacteria are closer to eukaryotes than Archaea - Differences…
to the Environment: Tropism: Stimuli to changes in the environment. Ex.: Migration of birds when the weather gets cold. Biotic vs. Abiotic: Biotic: Anything that is alive or anything that has been alive. Abiotic: Anything that has never been alive. Levels of Organization: Dear King Philip Came Over For Good Spaghetti: Domain Kingdom Phylum Class Order Family Genus Species Observation vs. Inference: Observation: Knowledge observed by the senses. Inference: Knowledge based on past experience. Controlled…
locus/loci, on a chromosome. A typical chromosome carries information for hundreds or thousands of genes. Chromosomes are found in the nucleus of all eukaryotic cells. Different organisms have different numbers of chromosomes- humans have 46. In most multicellular organisms chromosomes occur in sets or chromosomes. Haploid cells have half the normal number of chromosomes. Polyploids have three or more sets of chromosomes. Asexual Reproduction: A form of reproduction in which a new individual is produced…
R selection Use a batch culture also known as a serial culture (the liquid culture in the test tubes). Use this because they have an abundant amount of nutrients, just make sure that you transfer the culture to a new fresh tube everyday so the bacteria will continue in the exponential phase of growth, therefore always being selected to grow as fast as possible. (you could also use a chemostat which is a continuous culture system) K selection K selection you could use continuous culture device…
Chapter 1: Biology, the Study of Life Chapter Outline I. Fire Ants Have a Good Defense A. Fire ants take their name from their ability to sting. B. Fire ants sting in order to defend their home. C. The queen and worker ants live in chambers within and beneath a mound. D. The purpose of the queen is to produce eggs, which develop into larvae. E. Most offspring are sterile worker ants, but a few are male and female ants with the ability to reproduce. 1. These male…
will function 1 Require energy and nutrients. Energy comes from the chemical bonds, nutrients come from atoms in the food we eat. All the energy originated from the sun. Energy flows from the sun and is used or lost (or passed on to next trophic level). All the nutrients come from the mostly closed system of planet Earth being cycled around. Two ways: Autotrophs- produces Heterotrophs- consumers 2 Sense their internal and external environments 3 Respond to stimuli 4 Reproduce to pass on…
