|
Organism
|
made of one or more cells
|
|
|
The Characteristics of Organisms
|
made of one or more cells
use energy adapt to their environment respond to stimuli |
|
|
Cells
|
the basic units of structure and function in living things
|
|
|
The 2 Types of Organisms
|
Unicellular
Multicellular |
|
|
Unicellular
|
made of one cell
|
|
|
Multicellular
|
made of more than one cell
|
|
|
Sun
|
ultimate source of energy for most living things
|
|
|
Metabolism
|
chemical reactions in an organism that are used to build or break down materials as it carries out life processes
|
|
|
Adaptations
|
characteristics that help organisms survive in their environment
inherited |
|
|
Homeostasis
|
internal balance
regulations of an organism's internal environment maintains favorable (internal) conditions |
|
|
Stimulus
|
something that make organisms adjust or respond
happens first (before response) |
|
|
Response
|
reaction to stimulus or changes in the environment
|
|
|
Reproduction
|
living things coming from other living things
|
|
|
The 2 Main Types of Reproduction
|
Asexual
Sexual |
|
|
Spontaneous Generation
|
theory that organisms could come from something that was not alive
Redi & Pasteur disproved spontaneous generation |
|
|
Redi
|
placed spoiled meat in jars
jars that were uncovered had maggots jars that were covered had no maggots |
|
|
Pasteur
|
boiled 2 flasks of broth
flask with crooked neck did not spoil flask with straight neck spoiled |
|
|
Asexual Reproduction
|
prefix "a" means without, so asexual is without sex
only one parent organism offspring are identical to parent |
|
|
The 2 Types of Asexual Reproduction
|
Fission
Budding |
|
|
Fission
|
single-celled organism
the parent splits to form 2 different organisms |
|
|
Budding
|
multicellular organism
growth of a new organism from the parent |
|
|
Sexual Reproduction
|
sperm & egg join (fertilize) to form new organism
offspring are different from parent source of genetic variation (differences) |
|
|
Growth
|
increases the amount of living material
formation of new structures caused by formation of new cells hormone-driven (regulated) in plants & animals |
|
|
Developement
|
changes during the life of an organism
|
