4th grade Living Things Unit 4, Lesson 1

*Reformation* the effort to change or reform the Roman Catholic Church, which led to the establishment of Protestant churches *Renaissance* the period of the rebirth of learning in Europe between about 1300 and 1600 *Protestant* referring to Christian religions that grew out of the Reformation *humanism* a system of thought that focused on the nature, ideals, and achievements of human beings, rather than on the divine *Northern Italy* Where the Renaissance began in Europe. *Because there was a reawakening of interest in art, literature, and science between 1300 and 1600, it is fitting to call this period the Renaissance, since...

UNIT I Diversity in the Living World CHAPTER 1 The Living World ???????????????? ?What is Living ?Diversity in the living world ?Taxonomic Categories ?Taxonomical Aids The living world is very wonderful. It contains wide range of life forms. 1. 1What is living – Living organisms are self-replicating, evolving and self-regulating interactive systems capable of responding to external stimuli. Living organisms exhibit following distinctive characteristics. All Living Organisms grow: ?Twin characters of growth are increase in (a) mass and (b) number of individuals. Cell division leads to growth of an organism. ?External Growth is shown in non-living bodies where the accumulation...

MONERAThe Monera Kingdom, though not often recognized by all people, has a profound effect on all of our lives. Its cell structure is simple, containing one or a colony of cells. It has no nucleus, no organelles, a cell membrane, and only certain members of the kingdom have a cell wall. They most often obtain food by photosynthesis or feeding off another dead organism. It can move only through water or the organism that is hosting it. It reproduces not sexual or asexually, but through conjugation and fission. It is environmentally important because of its significance to the food chain....

Nitrogen Global winds Winds that follow regular patterns and paths Sea Breeze During the DAY cool dense air moves from the ocean towards the warm, less dense shore. Land Breeze During...

Classification in biology, is the identification, naming, and groupingof organisms into a formal system. The vast numbers of living forms arenamed and arranged in an orderly manner so that biologists all over theworld can be sure they know the exact organism that is being examinedand discussed. Groups of organisms must be defined by the selection ofimportant characteristics, or shared traits, that make the members ofeach group similar to one another and unlike members of other groups.Modern classification schemes also attempt to place groups intocategories that will reflect an understanding of the evolutionaryprocesses underlying the similarities and differences among organisms.Such categories...

TermDefinition chromatin one of a pair of duplicated chromosome Daughter cell Either of the two (or 4) cells formed when a cell undergoes cell division by mitosis (or meiosis). Mitosis A series of stages in the cell cycle of a somatic (body) cell in which the parent cell divides into 2 new daughter cells that are identical to the parent cell. Cell division The process by which a cell, called a parent cell, divides to form either 2 or 4 daughter cells. Somatic cells Any cell of a sexually reproducing organism that is not a germ cell. Also called a...

Protozoa Bacteria are prokaryotic cells; fungi, protozoa, algae, plants, and animals are composed of eukaryotic cells. 7. Viruses are not cells so they are neither prokaryotic nor eukaryotic. They can replicate only inside a living cell. Are protozoa prokaryotic or Eukaryotic? Unicellular eukaryotic organisms - these organisms are unicellular and are eukaryotes. They have membrane bound true nucleus and other membrane bound organelles. These are mainly free living or aquatic parasites like the protozoans, some fungi and algae or some protists. Are Protozoa unicellular or multicellular? In 21st-century systems of biological classification, the Protozoa are defined as a diverse group...

CellsCells are the basic unit of all life. Even though they are the smallestunit of life they are highly complex. Each cell has enough parts to it topractically survive on its own. There are two types of cells; the plant cell andthe animal cell. These two cells do not vary intensely, but there are somemajor factors that separate them completely.Animal cells are highly organized. The many parts that make up the cellwork in synch with each other. These parts are called organelles. The mostimportant organelle in the cell is the nucleus. The nucleus holds all of theblueprint information for the...

Living things make up the world as we know it. Living things are involved in ourlife constantly, seeing that we are alive. There are five characteristics thatare common to all living things. Living things are made up of one or more cells.Each cell is made up of living matter and is separated by a barrier thatencloses the cell from its surroundings. However, there are many different kindsof cells that make up living things. A single cell can be one organism. Theseorganisms are known as unicellular. Most of the organisms that we know best suchas people, trees, and dogs are all...
