|
The 4 needs of ALL living organisms |
•homeostasis •food •water •living space |
|
|
The 6 characteristics of ALL living organisms |
•contain similar chemicals •reproduce •respond to change •use energy •grow and develop •contain cells |
|
|
Characteristics of cells |
•have many parts that work together •make up ALL living organisms •share the characteristics of ALL living organisms |
|
|
Organelles |
•Cell membrane- Gate Keeper •Mitochondria -Power house/Mighty Mitochondria •Nucleus - The brain |
|
|
Cell membrane |
Controls what enters and exits the cell |
|
|
Mitochondria |
Breaks down nutrients to give energy to the cell |
|
|
Nucleus |
Controls what happens in the cell |
|
|
Characteristics that only plant cells have |
•Chlorplasts -captures light energy for photosynthesis •Cell Wall -gives plants support •Bigger Vacuole -supports the plant |
|
|
What do genes control |
How you: •look •behave •function |
|
|
What are genes recipes for |
Protiens |
|
|
Where do genes come from |
Your parent(s) |
|
|
Sexual reproduction offspring |
Is a combination of the two parents. They look similar to both parents and siblings. |
|
|
Asexual reproduction offspring |
Offspring is identical to parents |
|
|
Advantage to sexual reproduction |
GREATER VARIATION |
|
|
What is a mutation |
A mistake in a gene |
|
|
Are mutations important |
They are important because they introduce new traits to a population |
|
|
What is evolution |
How living organisms change over time |
|
|
What is evidence for evolution |
•Fossils •Similar Early Development •Similar Body Structure •DNA |
|
|
How does evolution happen |
•when there is a change in the environment •when there is a mutation |
|
|
In nature, who survives |
The organisms with the best traits |
|
|
What is classification |
Organisms grouped together based on their characteristic |
|
|
Why do we classify organisms |
This makes it easier to study organisms |
|
|
What are the 6 kingdoms? |
Archeabacteria,eubacteria, the plant kingdom, the animal kingdom, the fungus kingdom, and protists |
|
|
What characteristics do we use to put organisms into kingdoms |
•Are they unicelluar or multicellular •Are they consumers or producers •Do they reproduce sexually or asexually •Do they have a nucleus •do they have a cell wall |
|
|
What is ecology |
How organisms interact with living and nonlivong things in their environment |
|
|
What are the three ways organisms interact with each other |
•competition •symbiosis •predation |
|
|
Competition |
How organisms fight for resources |
|
|
Predation |
When an animal hunts another animal for food |
|
|
Symbiosis |
Organisms from different species with a close relationship in which at least one of them benifits from the relationship |
|
|
3 types of symbiosis |
•mutualism •paraitism •commensalism |
|
|
Decomposers |
Break down dead organisms and return nutrients to the soil |
|
|
Why are decomposers important |
They clean the environment (of dead organism) and they enrich the soil |
|
|
What are the three major types of decomposers |
•worms •fungi •bacteria |
