1

Properties of life

  • Order (exhibit complex organization)
  • Regulation (maintain internal environment)(temp by metabolism)
  • Evolutionary adaptation (happens slowly over time)(best suit organism to its environment)
  • Growth & Development (controlled by DNA)
  • Energy processing (get energy and transform it to a useful form)
  • Response to the environment (respond to environmental stimuli)
  • Reproduction (have babies)

2

Unifying themes of life

(Organization)

3

Living things

  • They possess life
  • They can give birth
  • Depend on food, air, food
  • Are sensitive & respond to stimuli
  • Growth & Development
  • Ex: humans, animals, plants, insects

4

Non-living things

  • No life
  • No babies
  • Do not depend on water, food, air
  • Not sensitive & no response to stimuli
  • No growth & Development
  • Ex: rock, pen, buildings.

5

Unifying themes of life

(Information)

The expression &  transmission of genetic information which is stored in the form of DNA in the chromosome transferred from parent to child.

6

Unifying themes of life

(Energy & Matter)

The transfer & Transformation of energy & matter

Energy tansformed from one source of another 

Producer-generate chemical energy

Consumers-feed on other organisms

7

Unifying themes of life

(Interactions)

From molecules to ecosytem, important in biological systems

ex: each organism interacts with other organisms and the environment.

8

Unifying themes of life

(Evolution)

accounts of the unity and diversity of life

living organisms are modified desecendants of common ancestors

9

Levels of biological organization

(The Biosphere)

  • Consists of all the environments on earth that support life
  • everything is included in the biosphere

10

Levels of biological organization 

(Ecosystems)

  • Consists of all living things alonng with nonliving environmental components
  • Includes all living things and non living things
  • ex: north american mountain meadow

 

11

Levels of biological organization

(Communities)

  • all the living organisma in a particular ecosystem
  • Only living organisms
  • Ex: All organisma in meadow ecosystem

12

Levels of biological organization

(Populations)

  • Consists of all the individuals of a species living within the specific area
  • Specific species & Spacific area
  • Ex: group of flowers

13

levels of biological organization

(Organisms)

  • An individual living things
  • Ex: each plant or animal

14

Levels of biological organization

(Organs)

  • Provide specific functions for the organism
  • Leaf, stem, root
  • organs combine they make an organism

15

Levels of biological organization

(Tissues)

 

  • Made of groups of similar cells
  • Tissues combine to make organs
  • Ex: mesophyll, epidermis

16

Levels of biological organization

(Cells)

  • Basic unit of life
  • plant cells
  • Life starts from cell

17

Levels of biological organization

(Organelles)

  • Membrane-bound structures with specific functions
  • Nucleus, chloroplast, mitochondria etcc.
  • different organelles combine to make cells

18

Levels of biological organization

(Molecules)

  • Clusters of atoms
  • chlorophyll, Proteins, DNA etc.
  • Lowest level, made up of a cluster of different atoms

19

Emergent Properties

  • Result from the arrangement & interaction of parts within a system
  • New arising propertity, at each level a new property emerges 
  • Ex: Cities, the brain, ant colonies, complex chemical systems

20

Prokaryotes

  • small, simple, not true nucleus
  • Bacteria, archaea

21

Eukaryotic

  • Membrane enclosed organelles
  • Plants, animals

22

DNA Structure

  • Chains arranged in a double helix structure
  • consist of four nucleotides
    • Adenine, thymine, cytosine, and guanine
  • Difference in DNA structure = diversity of life

23

Flow of energy & Chemical Cycling

24

Interaction between living and nonliving thing in the ecosystem

Explain

25

Unity & Diversity

  • Unity
    • Two species share certain common traits
  • Diversity
    • Certain heritable changes between two species after diverging from common ancestor

26

Living organism classification

  • total number of species that actually exist
  • species have been identified & named to date
  • each species given two-part name

27

Natural selection

Explain

28

Scientific Method

  • Observation
  • Question
  • Hypothesis
    • testable & falsible
  • Test-experiment or field study
    • collect data
    • statistical test
  • Results
  • Discussion/Conclusion

29

Types of Data

  • Qualitative data
    • info with color
  • Quantitative data
    • measured height & weight using statistics

30

Inductive reasoning

  • Generalizations are based on a large number of specific observations
  • make conclusion based on observation
  • Ex: the sun always rises in the east
