The organization of life - Lecture 1

Levels of organization

1. Celluar level

2. organizational level

3. Populational level

Celluar examples

atoms, molecules, organelles, cells

organismal examples

tissues, organs, organism, organ systems

populational examples

population, community, ecosystems, biome, biosphere

what is the fundamental element of matter

atoms

1. atoms are composed of the following subatomic particles

electrons, neurtrons, protons

2. what is 2 or more atoms join together into complex clusters

molecules like h2o or co2

3. what are large complex molecules called

macromolecules like carbohydrates

4. what is a specialized compartment of a cell are specialized compartments within a cell that perform a specific function.

organelles

5. The smallest level of organization that can be CONSIDERED to be ALIVE. Basic unit of LIFE. Made up of organelles, elements and are member-bound. All are either single or multicellular organisms

CELLS

6. group of similar cells that act as a functional unit. Group of CELLs with the same orgin that serve similar function

Tissues

what is the 4 major types of tissues

1. epidermal, 2. muscle, 3. connective. 4. nerve

7. consist of several different tissues grouped together in a strucutral and functionalunit

Organ like heart

8. made up of organs and tissues that work together for the same function

organ system 11 of them

9. single being living things that cannot survive without parts

organism

what is the basic unit of life

cell and in biology a single and multi celluar cell can refereed to as organism

10. a group of organisms of the same kind or specie that are living togehter in same place likely to interbreed

population

• what is organisms that are similar in apperence able to interbeed and reproduce

SPECIES

11. consists of all the popluations living togehter in ones place that interact

community

12. consists of all living things and nonlivng factos in area

ecosystem

13. major terrestrial assemblage that has living things and non living this over area

tropical forests, desert, ocean

14. biology at global level where it is a global ecological system intergreating all living things and earths regions like atmosphere, hydrosphere

biosphere
