Flashcards in Chapter 1 Deck (18):
1

biology

the scientific study of life

2

umbrella of biology

zoology: study of animals
mircobiology: the study of bacteria and viruses (non-living)
botany: the study of plants
mycology: the study of fungi
ecology: the study of how different organisms interact with their environments

3

lifes hierarchy of organization

1) biosphere
2) ecosystem
3) community
4) population
5) organism
6) organ systems
7) organs
8) tissues
9) cells
10) molecules
11) atoms

4

all living things on earth are within what is called the

biosphere: consists of all enviornments on earth hat supports life

5

the biosphere includes

most areas of land, water bodies, and the lower atmosphere

6

within the biosphere, the individual enviornments can be further broken down into

ecosystems: are a broad group that can be broken down all the way to the smallest level: the atomic level

7

cells are the

platform for life ( smallest unit of life)

8

molecules and atoms are

no longer living

9

ecosystem

these encompass all living organisms and non-living matter existing within a particular enviornment
this includes: all components of the enviornment with which the living organims interact
ex) soil, air, sunlight, water

10

community

these groups of organims composed of a number of different species that live within an ecosystem
ex) deer, lady bug, squirrel

11

population

these are all individuals of a particular species living within a particular area
ex) all of the lady bugs living within the park

12

organism

this is the individual unit of the population
ex) a lady bug from the lady bug population
a deer from the deer population

13

organ systems

this is a group of several organs which work together to preform specific functions
ex) the nervous system, the respiratory system, the circulatory system, ect

14

organs

this is a structure comprised of tissues which together as a group work to preform specific functions
ex) heart: composed of muscle tissue, connective tissue

15

tissues

these are made of similar cell types and each tissue has a specific function
each organ is made of several different tissues types

16

cells

these are membrane bound and the individual units of living matter
ex) liver tissue is composed of certain cell type which is liver cell (hepatocyte)

17

molecules

a molecule is made up of a cluster of atoms
ex) DNA, protien, sugar molecules
-fat composes outside layer
-water fills inside
-sugar/protein

18

atoms

these are the smallest unit of matter
molecules are composed of atoms
ex) nitrogen atoms, carbon atoms
