Colony

A group of cells that are permanently associated but do not communicate with one another.

Multicellularity

Organisms composed of many cells that are permenatly associated with one another, only in eukaryotes, can be large

Aggregation

A temporary collection of cells that come together for a period of time, communicate, and then separate.

Tissue

A distinct group of cells with similar structure and function.

Organ

Different tissues organized with a specialized structure and function.

Organ system

Various organs that carry out a major body function.

What are all of the kingdoms

Eubacteria, Archeabacteria, Protista, Fungi, Plantae, Animalia

Which kingdoms are multicellular and unicellular

Multi - Animalia, Plantae, Fungi, Protista

Uni - Eubacteria, Archaebacteria, Fungi, Protista

Both - Fungi, Protista

Which kingdom has a cell wall or cell membrane

All have cell wall except Animalia

What is the difference between colonial organism and a multicellular organism and aggregation

colonial organisms come together permanently but can not communicate, unlike aggregation where the organisms can come together temporarily but communicate. Neither are considered multicellular because both must be able to communicate and stay together permanently.

Which are autotroph and heterotroph

Autotroph - Plants

Heterotroph - Animals, Fungi

Both - Eubacteria, Archaebacteria, Protists

Differentation

cells develop a specialized form and function
