Question
Chapter 21.1, Problem 1TYK
Summary Introduction
Introduction:
The idea of the category called domain was introduced by an American biologist Carl Woese. Each species has been categorized into progressively smaller hierarchical groups according to modern taxonomy and each group at any level is called a taxon. Domains has been classified based on the information in the sequence of genes.

A scientist has discovered a new species and is tasked with identifying which of the kingdoms of life the organism might fit.
Multicellular with nuclei
Presence of a cell wall containing chitin
Heterotrophic
Non-motile
Question options:
Fungi
Protista
Plantae
Animalia
Protists are a group of organisms that are eukaryotic. However, they are a diverse group, with some of the members of the group having a more recent common ancestor with plants while others have a more recent common ancestor with animals. Algae are protists that are more closely related to plants than any other group.
Which characteristics would algae share with plants but NOT with animals?
Question options:
DNA
Ribosomes
Chloroplasts
Mitochondria
The three domains of life are Bacteria, Archaea, and Eukarya. Which of the following statements
best represents a significant difference between these domains?
All domains have membrane-bound organelles and a nucleus.
Eukarya have membrane-bound organelles and a nucleus, whereas Bacteria and Archaea do not.
Bacteria and Archaea have membrane-bound organelles and a nucleus, whereas Eukarya do not.
None of the domains have membrane-bound organelles and a nucleus.

The domain (Eukarya / Prokarya) includes four kingdoms. The kingdom (Plantae / Fungi) was first to make the transition to land. The kingdom (Animalia / Plantae) is most closely related to the kingdom Fungi.arrow_forward
