metabolism

Back 3

sum of all processes that allow an organism to sustain life; eating

Front 4

adaptation

Back 4

any physical/behavioral feature that allows an organism to better adapt to its environment

6. interpret data and draw conculsions

Front 8

hypothesis

Back 8

educated guess with 'should' in it

Front 9

variable

Back 9

feature of an experiment that can be changed

Front 10

control group

Back 10

group in an experiment that is constant and faces no new change

Front 11

experimental group

Back 11

group in an experiment that tests the hypothesis and compared to the control group

Front 12

1. hierarchy or organization

2. hierarchy eample

Back 12

1. organism/features arranged in graded or specific groupings

2. organelles - cells - tissues - organs - organ system; classification system

Front 13

1. holistic approach

2. reductionist approach

Back 13

1. study organism as a whole

2. study organism by dissecting it

Front 14

taxanomic classification

Back 14

domain, kingdom, phylum, class, order, family, genus, species, subspieces

Front 15

six kingdoms

Back 15

archeabacteria, eubacteria, plantae, fungi, protista, animalia

Front 16

archeabacteria

Back 16

live in extreme, unusual environments

Front 17

eubacteria

Back 17

true bacteria that are prokaryotes and common in daily life

Front 18

protista

Back 18

"grab bag"

Front 19

fungi

Back 19

nonphotosynthetic, secrete arsenal of enzymes

Front 20

plantae

Back 20

photosynthestic

Front 21

animalia

Back 21

depend on plantae kingdom heavily

Front 22

prokaryotic vs eukaryotic

Back 22

prokaryotic - have no true nucleus and lack most membrane bound organelles

eukaryotic - have a true nucleus and have membrane bound organelles

Front 23

DNA

Back 23

molecule responsible for order in living organisms; contains biologically encoded instructions for continuity of species

Front 24

1. cell

2. discovered by...

Back 24

1. basic unit of structure for all living organisms

2. Robert Hooka

Front 25

cell theory contention by Schleiden and Schwann

Back 25

1. all cells come from pre-existing cells

2. all living things consist of one or more cell

3. cell is the basic unit of function and structure in all living oragnisms

Front 26

species biological defintion

Back 26

group of organisms capable of successfully interbreeding and producing viable offspring

Front 27

taxonomy vs. nomenclature

Back 27

taxonomy - classification of organisms

nomenclature - naming of organisms

Front 28

Linnaeus' binomial system of nomenclature

Back 28

how to write the names of organisms; genus first
