The scientific study of life. The study of biology encompasses a wide scale of size and a huge variety of life, both past and present. |
|
|
The Properties of Life |
1. Order 2. Regulation 3. Growth and Development 4. Energy Utilization 5. Response to the environment 6. Reproduction 7. Evolution

|
Cells are either prokaryotic or eukaryotic |
prokaryotic- simple, small and lacking membrane-bounded organelles such as the nucleus. eukaryotic- more complex, larger and contains a nucleus and other membrane-bounded organelles. |
|
|
3 Domains of living organisims |
Bacteria, Archaea and Eukaraya |
|
|
Bacteria and Archeaa Domain |
are a Prokaryotes |
|
|
Eukarya Domain |
is a Eukaryotes- then separated into 3 kingdoms. Plantae, Fungi and Animalia (humans) |

|
Taxonomy |
the system scientists use to organize living things. Branch of biology that names and classifies species, formalizes this heirarchical ordering |
|
|
theory |

|
Natural Selection
Artificial Selection |
selective breeding of animals and plants
natural selection over span of time |
