Taxonomy and 5 Kingdoms Overview

A branch of science that deals with classifying organisms.

A hierarchical system used to classify organisms, starting with broad groups and becoming increasingly specific.

A system of classification that divides living organisms into five major groups: Animal, Plant, Fungus, Protoctist, and Bacteria.

Organisms that lack a membrane-bound nucleus in their cells.

Organisms with a membrane-bound nucleus in their cells.

A thin layer that surrounds all cells, regulating what enters and exits.

The inner region of a cell, containing all the components except the nucleus.

Small structures within a cell that are responsible for protein synthesis.

The genetic material of a cell, containing the information necessary for life.

A distinct, membrane-bound organelle that contains the genetic material of a Eukaryotic cell.

A network of membranes that plays a role in protein synthesis and transport.

Double-membrane organelles that convert energy from food into usable energy.

Characterized by a lack of membrane-bound organelles and circular DNA.

Characterized by membrane-bound organelles, including a nucleus containing linear DNA.

Organisms that are made up of one single cell.

Organisms that are made up of multiple cells.

Organisms that obtain nutrition by consuming other organisms.

Organisms that produce their own food through photosynthesis.

A rigid outer layer that surrounds the cell, providing structure and protection.

Organisms belonging to the Animal Kingdom are multicellular, eukaryotic, lack a cell wall, and are heterotrophic.

Organisms belonging to the Plant Kingdom are multicellular, eukaryotic, have a cell wall made of cellulose, and are autotrophic.

Organisms belonging to the Fungi Kingdom are multicellular, eukaryotic, have a cell wall made of chitin, and are heterotrophic.

Organisms belonging to the Protoctist Kingdom are mostly unicellular, eukaryotic, lack a cell wall (except for some species), and are both autotrophic and heterotrophic.

Organisms belonging to the Bacteria Kingdom are unicellular, prokaryotic, have a cell wall made of peptidoglycan, and are both autotrophic and heterotrophic.
