24
Q

the study of life

25
Organisms changed over time
Evolve
26
a belief that living organisms could develop from nonliving materials
Abiogenesis/Spontaneous Generation
27
an Italian scientist conducted an experiment to disprove spontaneous generation
Francisco Redi (1668)
28
put an end to the belief in spontaneous generation
The Swan-necked Flask Experiment
29
A theory or principle that life came from pre-existing life. This means that **life comes from other living things by reproduction**
Biogenesis
29
Father of Bacteriology and became famous for his Pasteurization process
Louis Pasteur
30
made of one cell
Unicellular
30
- All living things are composed of cells - In multicellular organisms, many are specialized to perform specific functions - Cells are always very small - The size of multi-celled organisms depends on the number of cells NOT their size - Made up of at least one cell
Cellular Composition
31
made up of two or more cells (plants, fungi, animals)
Multicellular
32
is the formation of two cells from a preexisting cell
Cell division
32
the process by which an adult organism arise
Development
33
the process of producing new individuals
Reproduction
34
- place to place (bear running, bird flying) - external part (phototropism, plants orient leaves toward sun) - internal (cytoplasmic streaming)
Movement
35
is a change that makes it better suited to its environment
Adaptation
36
fur changes color in the arctic fox during winter
Short term adaptation
37
changes occur over many generations and are inherited
Long term adaptation
38
ability to adapt to their environment through the process
Evolution
39
"survival of the fittest"
Natural Selection
40
behavioral adaptation
Bird migration
41
physiological adaptation
Human body temperature
42
physiological adaptation
Hibernation
43
structural adaptation
Hare ear length
44
adaptation for defense
Camouflage/mimicry
45
- sum of all chemical processes - set of chemical reactions that convert "food" into energy - organisms use energy obtained from food
Metabolism
46
2 types of metabolism
- Anabolism - Catabolism
47
- organized at both the molecular and cellular levels - take in substances from the environment and organize them in complex ways - specific cell structures (organelles) carry out particular functions
Organization
48
- Maintain stable internal conditions - self-adjusting balance to maintain a steady state
Homeostasis
49
same, steady
Homeo
50
state
Stasis
51
