CHARACTERISTICS OF LIVING THINGS

The 8 Characteristics of LifeAll Living Things… are made up of cells

(one cell = unicellular / many cells = multicellular) reproduce

(on their own = asexual / with another parent = sexual)have a genetic code (DNA) with instructions for growing and reproducinggrow and developuse energy and materialsrespond to their environment control the conditions inside their bodies (maintain

homeostasis)Groups of living things adapt/evolve/change over time.

Objectives for Class:• List 6 of 8 characteristics that all living things share

Two Main Cell Types

Eukaryotic(eu = true; karyote = kernel/nucleus) Cells that have a nucleus in which their

DNA/ chromosomes are stored Cells that are larger and more complex

Prokaryotic(pro = before; karyote = kernel/nucleus) Cells that don’t have a nucleus (DNA just

floats around in the cell) Cells that are smaller and simpler

Class Objective: Distinguish between Prokaryotic and Eukaryotic Cells

White Blood Cell w/ Cocci (bacteria)

Epithelial Cells w/ Bacilli (bacteria)

Two main cell types:PROKARYOTES and EUKARYOTES

Class Objective: Distinguish between Prokaryotic and Eukaryotic Cells

Prokaryotes Eukaryotes

Class Objective: Distinguish between Prokaryotic and Eukaryotic Cells

Two main cell types:PROKARYOTES and EUKARYOTES

DOMAINS & KINGDOMS OF LIFE

Domain Bacteria

unicellular/microscopic prokaryotic (tiny cells with no nucleus) very diverse – live and eat in many

different ways

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

Domain Archaea

unicellular/microscopic Prokaryotic (no nucleus) live in extreme

environments (very hot, salty, or acidic places)

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

Domain Eukarya

unicellular OR multicellular all have nucleus eukaryotic (bigger cells w/ nucleus and

organelles) includes 4 Kingdoms:

Protista, Fungi, Plantae, Animalia

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

Kingdom Protista

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

all are eukaryotic; most are unicellular

most live in water “miscellaneous” category –

some are like plant cells, some are like animal cells

Kingdom Fungi

mostly multicellular decomposers (feed on

dead/decaying things)ex: mushrooms, mold, yeast

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

Kingdom Plantae

multicellular use photosynthesis to make

food from sunlight, CO2, and water

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

Kingdom Animalia

multicellular eat other living things for

food most can move

Objectives for Class:1. Identify and explain two defining characteristics of each kingdom and domain.

Species Definition and Examples

Species – a specific group of living things that have similar characteristics, similar DNA, and can reproduce with each other to make fertile offspring (this means their babies can also have babies)

Example: tiger + tiger = baby tiger (which grows up to reproduce)

lion + tiger = liger (a hybrid which can’t reproduce)

Every species has a 2-part Latin name: Genus speciesEx: Canis lupus (wolf)Genus
