1

What are the characteristics of living organisms?

Order
Reproduction
Growth and Development
Energy processing
Response to environment
Regulation
Evolutionary adaptation

2

Define: emergent properties

properties that emerge as a result of arrangement and interaction of components

3

Schleiden and Schwann 1839

Cell Theory
-all organisms are made up of cells
-all existing cells are made up of previously existing cells (Pastuer)

4

lipid bilayer

plasma membrane that surrounds all cells

5

Define: organelles

small structures within a cell that perform a specific function

6

protoplasm

all of the living material in cells

7

cytoplasm

contents of the cell between the plasma membrane and the nucleus

8

cytosol

the semi-fluid portion of the cytoplasm

9

prokaryotic

relatively simple and small do not contain a nucleus, most do not contain other membrane bounded organelles (can still have DNA, not in a nucleus)

10

eukaryotic

contain nucleus, contain other membrane bounded organelles *humans

11

reductionism

reduction of complex systems to simpler components that are more manageable to study

12

systems biology

construct models for the dynamic behavior of whole biological systems

13

two kingdoms that are outdated

Monera, Protista

14

three Domain scheme

Bacteria
Archaea
Eukarya

15

Three (and a half) kingdoms

Fungi,
Plantae
Animalia
Protists (artificial group)

16

taxonomy

Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

17

Taxonomy of Humans

Eukarya
Animalia
Chordata
Mammalia
Primates
Hominidae
Homo (underlined)
Homo sapiens (underlined)

18

Inductive reasoning

from specific to general

19

Deductive reasoning

from general to specific

20

Discovery Science

describes nature through observation and analysis of data

21

Correlative Study

A Correlative is a procedure used to test a hypothesis through additional observations. Without manipulating an independent variable, it exploits preexisting variation.

22

Causative Study

A Controlled Experiment is a procedure used to test a hypothesis using an Experimental group and one or more control Groups. Scientists manipulate an independent variable and measure the effect on a dependent variable.

23

Theory

a concept that is well supported by evidence and is widely accepted by the scientific community. It is broader than a hypothesis and is supported by much more evidence.

24

feedback mechanism

feedback mechanisms regulate biological systems

25

negative feedback

output or product of a process slows that process

26

positive feedback

output or product of a process speeds up that process

27

hydrophobic

do not dissolve in water

28

hydrocarbons

do not dissolve in water

29

hydrophilic

do dissolve/interact with water

30
