GAIA Ecosphere Ecosystem Organism System Organ Tissue Population Atom Molecule Macromolecule Organelle Cell Tissue Organ System Organism Population Community Ecosystem Ecosphere GAIA
ATOMS Smallest part of matter NON-living
Molecules 2 or more bonded atoms Form compounds NON-living
Organic molecules carbohydrates, proteins, lipids and nucleic acids. Inorganic molecules Water, Salts And vitamins.
Macromolecule Very large molecules NON-living
Organelles “Tiny organs” Made of macromolecules
Cell Made of organelles Basic unit of structure & function LIVING
Tissue The same kind cell working together Living
Tissues found in the leaf A tissue is a group of cells of similar structure that perform a shared function Animal tissues: muscle nervous upper epidermal tissue palisade mesophyll spongy mesophyll tissue lower epidermal Tissues found in the leaf Cross-section of a leaf Slide taken from clickbiology.com
Organs Tissues that work together Living
heart lungs liver stomach brain kidneys An organ is a structure made of a group of tissues working together to perform specific functions heart lungs liver stomach brain kidneys Plant organs include the stem and the leaves Slide taken from clickbiology.com
An organ system is a group of organs that coordinate to perform related functions lymphatic system digestive system reproductive system skeletal system endocrine system respiratory system excretory system muscular system nervous system circulatory system In plants the shoot is an organ system consisting of leaves and the stem Slide taken from clickbiology.com
Systems Organs that work together Living
Organism Entire living things (organisms) Usually made of systems May be a single cell Living
What type of organism is this? Unicellular or pluricellular? http://israel-biologialacelula.blogspot.com/
Population Same type of organism living together
Community Several populations living together Population interact
Ecosystem A biotic (living) community plus the abiotic (nonliving) features
Biome Similar ecosystems on earth together
Ecosphere Whole living layer around the globe Includes abiotic features

Who is GAIA? Image from Sandra Ingerman's Blog
Who is GAIA? In Greek mythology, Gaia was a Titan who personified Earth. She was the mother of several later Titans, including Cronus, Rhea, Iapetus (father of Atlas), and Oceanus. She was worshipped as the Earth mother goddess. http://robinfowler.suite101.com/who-is-gaia--a11020#ixzz1YJfggRBL
