2 Organization & Cells- organization is a high degree of order within an organism's internal and external parts and in its interactions with the living world.-cell is the smallest unit that can perform all of life's processes.-unicellular is when an organism is made up of only one cell.
3 Response to StimuliPhysical or chemical change in the internal or external environment.Organisms need to respond and react to changes in their environment to stay alive.
4 HomeostasisHomeostasis, the maintenance of a stable level of internal conditions. (Example: A cell can control the amount of water in its body by taking in or releasing water. If a cell gets too much water it will suffocate itself and die and visa versa.)All living things have mechanisms that help them control their internal conditions and without them, everything would die.
5 HomeostasisOrganisms have regulators that help control their inner conditions like temperature, water content, and the uptake of nutrients. (Example: An owl can keep its body temperature at 40 degrees Celsius by burning fuel for heat. Also, its feathers help to provide extra added heat to protect it.)
6 Metabolismmetabolism- the sum of all the chemical reactions that take in and transform energy and materials from the environmentplants, algae, and some bacteria = photosynthesisother organisms eat prey for metabosome organisms depend on food energy from other organisms
7 Growth & Development All living things grow in size Organisms mature through cell enlargment and divisionCell division is the formation of 2 new cells from an existing cellAn adult organism is composed of many different cells that serve many different purposesCells commonly enlarge following cell division
8 Growth & DevelopmentDevelopment is the process that an organism takes part in to become a fully formed adultDevelopment involves cell division, differentation, and specializationAs a result of specialization, different cells have different rolesSome non-living things, like crystals and icicles grow by accumulating more and more of the material or mineral they are composed of
9 ReproductionReproduction is the process of organisms producing new ones.Reproduction is not essential for the survival of an organism.Essential for continuation of species.Organisms transmit hereditary ingo to their offspringA short segment of DNA that contains a single trait is called a gene.
10 ReproductionDNA contians all the genes that the cell will ever need for making the structures and chemicals necessary for life.Sexual reproduction- hereditary ingo recombines form two organisms of same speices.
11 Change Through Time Living organism evolve or change through time. Ability of population of organism to change over time is important for survival.Explaining the diversity of life-forms.
