1 (unicellular) or more Cells (multicellular) are found in all living things! • A person can have TRILLIONS of cells making up their body!

All organisms are made of cells Unicellular vs Multicellular

All organisms need energy • Autotroph – Can produce their own food. • Heterotroph - Cannot produce its own food. Needs to eat.

All organisms need energy • Autotroph – Can produce their own food. PLANTS! • Heterotroph - Cannot produce its own food. Needs to eat.

All organisms need energy • Autotroph – Can produce their own food. PLANTS! • Heterotroph - Cannot produce its own food. Needs to eat. ANIMALS!

All organisms reproduce • Asexual – One parent produces offspring -identical to parent • Sexual - Two parents join to form a new individual- different from parents

Carolus Linnaeus • Father of modern taxonomy • The science of classifying organisms is called taxonomy • Organisms are grouped into based on similarities

Three Domains Bacteria Archaea Eukarya

Three Domains (the broadest level of classification!) Bacteria Archaea Eukarya

Kingdoms of Eukarya

• Top is very broad, diverse • Species is the most specific grouping

Domain: Archaea Prokaryotes, Unicellular Energy Source - autotroph or heterotrophs Reproduction - Asexual Characteristics – Live in harsh environments – extreme heat/cold, lacks oxygen, salty, etc.

Domain: Bacteria Prokaryote, Unicellular Energy Source - autotroph or heterotrophs Reproduction- asexual Characteristics – Often do need oxygen – Bacteria can make us sick, but some live in our intestines, or are used to make cheese

Kingdom Animalia (Animal) Domain Eukarya Eukaryote, Multicellular Energy Source: Heterotroph (eat other organisms) Reproduction – Sexual, although some exceptions

Kingdom Plantae (Plant) Domain Eukarya Eukaryote, Multicellular Energy Sources – Autotroph (photosynthesis) Reproduction- sexual, some asexual

Kingdom Fungi Domain Eukaryota Eukaryote, Multicellular or Unicellular Energy Sources – Heterotroph (decomposer) Reproduction- sexual or asexual

Kingdom Protista (Protist) Domain Eukarya Eukaryote, Unicellular Energy Source: heterotroph or autotroph Reproduction – Asexual Amoeba Paramecium Green Algae

Sexual Reproduction The offspring (kids) gets genetic information from a 2 parents (mom and dad).

Asexual Reproduction • The offspring does not have a mom and dad, but only 1 parent. The offspring are genetically identical to their parent. This is common with unicellular organism and certain types of plants
