1. What makes something alive ?

2. What are living things? There are certain criteria that determine if something is living. Yes, ALL 7 criteria must be met. Do ALL 7 criteria have to be met?

3. Organism Anything that possesses all of the following characteristics of life. Living things R-CHARGEED !!

4. R - All living things produce offspring. Making copies of individuals by genetic transfer, sexually or asexually. eproduce

5. -Living organisms show an orderly structure (made up of cells) Examples: Leaf Cross-section of worm Centipede C - ells

6. Example: The ability to maintain internal conditions separate from an outside environment. The human body maintains an average temperature of 98.6 ºF. H - omeostasis

7. A living organism will respond to an environmental condition called a stimulus. An adaptation is any characteristic of an organism that improves its chances of surviving in its environment A plant growing in a specific direction due to a light stimulus. A - dapt to the environment R - espond to stimuli

8. Getting Bigger / Increasing material All of the changes that take place during the life of an organism. Maturing. Amoeba absorbing nutrients Growth rings in a tree G - rowth D - evelopment

9. Metabolism. Chemical and energy transformations. All organisms need energy for all life activities. Even thinking requires a considerable amount of energy. Transforming glucose into ATP for energy (to do work). E - energy

10. The gradual accumulation of adaptations due to environmental stimuli. (Organisms with more suitable adaptations are more likely to survive and reproduce) Example: Owls, and other nocturnal animals have evolved large eyes for better night vision. E - evolve

29. How many characteristics of life must an organism possess to be considered alive? 1234567891011121314151617181920 21222324252627282930 1. 1 2. 3 3. 5 4. 2 and a half 5. All of them

32. How are living things organized? There are various levels of organization: and get bigger. Let’s start small

33. 1) Atoms Atoms are the smallest unit of matter that have the chemical properties of a particular element. Examples: Carbon, Hydrogen, Oxygen…

34. 2) Molecules Molecules that are the small building blocks from which larger molecules are made. Examples: Glucose Amino Acid Water

35. 3) Macromolecules Large molecules consisting of many subunits. Examples: Protein Cellulose

36. 4) Organelles Examples: Specialized structures inside of a cell. Mitochondria Cell Membrane

37. 5) Cells Example: The smallest unit of biological organization that biologists consider alive.

38. 6) Tissue A group of distinct and similar cells that carry out a specific set of functions. Examples: Muscle Skin

39. 7) Organ Examples: Groups of tissues organized together to carry out a particular set of functions. Brain Stomach

40. 8) Organ System Example: Groups of organs that function together to carry out broad sets of functions.

41. 9) Organism (or individual) Examples: Individual that has its own distinct existence as a complex, reproducing unit.

42. 10) Population Examples: Group of freely interacting and breeding individuals of the same species. School of fish Herd of Zebra

43. 11) Community Example: Populations of different species living and interacting together in a distinct area. Marine community

44. 12) Ecosystem Examples: Distinguishable groups of species and the abiotic (non-living) components of the environment with which the living creatures interact.

45. 13.) Biome Geographically defined area based on climate and environmental conditions.

46. 14.) Biosphere I’m sure you can figure this one out!
