1 Levels of Organization of Life Presentation based on one from http://people.hofstra.edu/geotrans/eng/ch8en/conc8en/envisys.html http://people.hofstra.edu/geotrans/eng/ch8en/conc8en/envisys.html

2 Atom Molecule Macromolecule Organelle Cell Tissue Organ System Organism Population Community Ecosystem Ecosphere GAIA

3 ATOMS Smallest part of matter NON-living

4 Molecules 2 or more bonded atoms Form compounds NON-living

5 Organic Organic molecules carbohydrates, proteins, lipids and nucleic acids. Inorganic Inorganic molecules Water, Salts And vitamins.

6 Macromolecule Very large molecules NON-living

7 Organelles “Tiny organs” Made of macromolecules

8 Cell Made of organelles Basic unit of structure & function LIVING

9 Tissue The same kind cell working together Living

10 A tissue is a group of cells of similar structure that perform a shared function Animal tissues : muscle nervous upper epidermal tissue palisade mesophyll tissue spongy mesophyll tissue lower epidermal tissue Tissues found in the leaf Cross-section of a leaf Slide taken from clickbiology.com

11 Organs Tissues that work together Living

12 An organ is a structure made of a group of tissues working together to perform specific functions Plant organs include the stem and the leaves heart stomach lungs liver brain kidneys Slide taken from clickbiology.com

13 An organ system is a group of organs that coordinate to perform related functions In plants the shoot is an organ system consisting of leaves and the stem lymphatic system respiratory system digestive system excretory system reproductive system muscular system skeletal system nervous system endocrine system circulatory system Slide taken from clickbiology.com

14 Systems Organs that work together Living

15 Organism Entire living things (organisms) Usually made of systems May be a single cell Living

16 What type of organism is this? Unicellular or pluricellular? http://israel-biologialacelula.blogspot.com/

17 Population Same type of organism living together

18 Community Several populations living together Population interact

19 Ecosystem A biotic (living) community plus the abiotic (nonliving) features

20 Biome Similar ecosystems on earth together

21 Ecosphere Whole living layer around the globe Includes abiotic features

23 Who is GAIA? Image from Sandra Ingerman's Blog

24 Who is GAIA? Earth the Earth mother 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.TitanAtlas http://robinfowler.suite101.com/who-is-gaia--a11020#ixzz1YJfggRBL

25 Can you write the levels of organization of life?
