Classification
Heterotrophic/ Autotrophic (TEKS 6.12D)*

Heterotrophic/ Autotrophic
o Heterotrophic- gets nutrition from an outside source
 Examples are anything that eats: consumers, animals, bacteria, fungi
o Autotrophic- self feeder; makes own food through photosynthesis or chemosynthesis
 Examples are producers; plants and some acheabacteria
Domains, Kingdoms (TEKS 6.12C)

Levels of Organization (Domains, Kingdoms)
Three DOMAINS that contain kingdoms
ARCHEA
BACTERIA
Archaebacteria
Eubacteria
Unicellular, asexual reproduction (binary fission),
heterotrophic, Prokaryotic, simple, no nucleus
Live in your body and
elsewhere and can be
helpful or harmful
Live in extreme
environments
Autotrophic,
asexual
reproduction,
unicellular, cell
wall
EUKARYA
Plants,
animals,
fungi,
protist
Heterotrophic,
unicellular,
asexual
reproduction, cell
wall
Multicellular, sexual reproduction, Eukaryotic, cells
have nucleus
Unicellular/Multi-cellular (TEKS 6.12D)*

Organisms are composed of one or more cells: Unicellular/ Multi-cellular
o Unicellular- one celled organisms; the individual organism is made up of only one
cell like bacteria.
o Multi-cellular- many celled organisms; the organism is made up of many cells
working together like humans.
 Cellstissuesorganssystemsorganism
Mode of Reproduction (TEKS 6.12D)*
o Sexual reproduction
 Sex cells are created through meiosis
 makes 4 daughter cells with half the genetic information
 Needs the genetic information of two parents to create a unique
organism allowing for more genetic variation.
o Asexual reproduction
 Requires the genetic of only one parent
 Offspring is genetically identical to the parent
 Types of asexual reproduction:
 Budding – organism grows out of the adult
 Binary fission- like mitosis, occurs in bacteria
 Parthenogenesis- whip tail lizards in New Mexico are all females and
lay eggs that hatch to be clones of the mother.
 Regeneration- The regrowth of a missing limb, like lizard tails and
starfish.
Biotic factors
Living or from a living organism
All Domains (Eukarya, Archaea, Bacteria)
All Kingdoms (Plantae, Animalia, Fungi, Protista,
Archaebacteria, Eubacteria)
Made from one or more cells
Multicellular or unicellular
Abiotic factors
Non-living (as in never been alive)
Sunlight
Temperature
Air
Water
Soil (rocks, metals, minerals)
Ecosystems

describe air temperature, annual precipitation, number of producers, number of
consumers, soil composition, etc. as biotic or abiotic parts of an ecosystem:
o biotic- Bio (life) All living organisms
 abiotic- A(no or without) Bio (life) Plants
without life, such as S. A. W. S.:
 Animals
o Soil
 Bacteria
 Rocks
 Protista
o Air
 Fungi
o Water
o Sunlight
 Temperature

describe the levels of organization within an ecosystem:
o
o
o
o
Organism– member of a single species in a given area
Population- members of the same species in a region
Community- different species in a region
Ecosystem– all the communities in an area and the abiotic factors that affect
them.
Organism  Population  Community  Ecosystem
Classification


understand that all organisms are composed of one or more cells
recognize that the presence of a nucleus determines whether a cell is;
o prokaryotic
or
eukaryotic

identify the basic characteristics of organisms:
o Prokaryotic-before nucleus,
simple, not very complex, smaller,
examples are eubacteria and
archaebacteria
o Eukaryotic- true nucleus,
complex, larger, membrane
bound organelles. Examples are
euglena, body cells.
o Unicellular – one celled organism,
examples are all bacteria and
the kingdom Protista
o Multicellular- organisms made up
of more than one cell. Examples
are plants, animals, fungi.
CELLS – the basic unit of all life, organisms are made up of one or more cells.
Microscope- tool used to observe things too small to see with the naked eye.
