Common Properties of living things
1. Order
2. Reproduction
3. Growth and Development
4. Energy Processing
5. Response to environment
6. Regulation
7, Evolutionary adaptation
Molecule
Cluster of small chemical units called atoms held together by a chemical bond
Organelle
A membrane of-enclosed structure that performs a specific function in a cell
Cell
Fundamental unit of life
Tissue
Made up of a group of similar cells that perform a specific function
Organ
Made up of several different tissues
Organ System
Consists of several organs that cooperate in a specific function (I.e circulatory system & nervous system)
Organism
An individual living thing
Population
Includes all the individuals of a particular species living in an area
Community
Entire array of organisms in an ecosystem
Ecosystem
Consists of all the organisms living in a particular area. Interacting with the physical components (i.e air, soil, water)
Biosphere
All of the environments on Earth that support life
Emergent Properties
New properties that arise with each step upward in the hierarchy of life.
Eukaryotic Cell
A type of cell that has a membrane-enclosed nucleus and other membrane-enclosed organelles.
Prokaryotic Cell
A type of cell lacking a membrane- enclosed nucleus and other membrane-enclosed organelles. NO NUCLEUS
Diversity of Life THREE Domains
1.Taxonomy
2. Archaea
3. Eukaryotes
Four Kingdoms
1. Protists
2. Animal
3. Plant
4. Fungus
Protist Kingdom
Single celled animals that survive by consuming other living things (Protozoa)
i.e Amoeba and algae
Animal Kingdom
Survive by consuming other living things
Plant Kingdom
Survive by photosynthesis
Fungus Kingdom
Most survive by decomposing other (usually dead) living things.
Evolution
The genetic changes in a population from generation to generation. Also, species living today are descendants of ancestral species.
Natural Selection
A process in which individuals with certain inherited traits are more likely to survive and reproduce than are individuals that do no have those traits
Inductive Reasoning
A type of logic in which generalizations are based on a large number of specific observations.
Hypothesis
A proposed explanation for a set of observations
Deductive Reasoning
A type of logic in which specific results are predicted from a general premise.
