Which belongs in the domain eukarya
The third domain, Eukarya, consists of organisms whose cells have a nucleus. Bacteria and Archaea seem to have a lot in common at first. Just as the name implies, the domain Bacteria contains bacteria. The microbes in the domain Archaea look like bacteria, but are different in a few essential ways. Jan 23, Explanation: The presence of nucleus which contains genetic material and is enclosed by a nuclear membrane sets them apart from prokaryotic cells. The kingdoms associated with Eukarya are Plantae, Animalia and Fungi kingdoms, Eukaryotes represent a tiny minority of all living things , but due to their much larger size , eukaryotes collective world wide biomass is estimated at about equal to that of prokaryotes.

Presence of membrane bound organelles 2. Presence of a double membrane nucleus 3. Cell division is different 4. Mode of reproduction may vary Kingdoms Under Domain Eukarya 1. Fungi 2. Animalia 3.

Rhizaria 6. Monera Bacteria. Prokarya Bacteria. Presence of membrane bound organelles. In cells, the job of organelles is to carry out physiological and metabolic processes that are important for the survival of the cell.
Other organelles function for support and motility. Such were the intracellular filaments, cilia, and flagella. Presence of a double membrane nucleus. Cell division is different. During mitosis, the nucleus of the cell divides into two while the genetic material, present as chromosomes are equally distributed to each opposite of the cell.
Following that step is the cytokinesis, which is when the cytoplasm of the cell divides, developing it the equal division of the genetic material.
Mode of reproduction may vary. During asexual reproduction, the cell divides through mitosis followed by cytokinesis. On the other hand, they may also reproduce sexually by involving their sex cells called the gametes. In this type of reproduction, the offspring inherits a chromosome from each of its parents.

Fungi Kingdom: Fungi are unicellular or multicellular organisms with eukaryotic cell types.
The cells have cell walls but are not organized into tissues. They do not carry out photosynthesis and obtain nutrients through absorption. Examples include sac fungi, club fungi, yeasts, and molds. Plantae Kingdom: Plants are multicellular organisms composed of eukaryotic cells. The cells are organized into tissues and have cell walls. They obtain nutrients by photosynthesis and absorption. Examples include mosses, ferns, conifers, and flowering plants. Animalia Kingdom: Animals are multicellular organisms composed of eukaryotic cells.
The cells are organized into tissues and lack cell walls. They do not carry out photosynthesis and obtain nutrients primarily by ingestion. Examples include sponges, worms, insects, and vertebrates. Summary Phylogeny refers to the evolutionary relationships between organisms.
Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs rRNA , the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
Microorganism transfer genes to other microorganisms through horizontal gene transfer - the transfer of DNA to an organism that is not its offspring. Contributors and Attributions Dr.
