What does Eukarya mean?

Answer 1

The Eukarya (eukaryotes)

The Eukarya (also spelled Eucarya) possess the following characteristics:

• Eukarya have eukaryotic cells.
• Like the Bacteria, they have membranes composed of unbranched fatty acid chains attached to glycerol byester linkages (see Fig. 1).
• Not all Eukarya possess cells with a cell wall, but for those Eukarya having a cell wall, that wall contains no peptidoglycan.
• Eukarya are resistant to traditional antibacterial antibiotics but are sensitive to most antibiotics that affect eukaryotic cells.
• Eukarya contain rRNA that is unique to theEukarya as indicated by the presence molecular regions distinctly different from the rRNA of Archaea and Bacteria.

The Eukarya are subdivided into the following kingdoms:a. Protista Kingdom

Protista are simple, predominately unicellular eukaryotic organisms. Examples includes slime molds, euglenoids, algae, and protozoans. b. 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. c. 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. d. 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.

Answer 2

Eukaryotes have a membrane-bound nucleus and membrane-bound organelles. Organism whose cells have (1) chromosomes with nucleosomal structure and separated from the cytoplasm by a two-membrane nuclear envelope, and (2) compartmentalization of functions in distinct cytoplasmic organelles. Contrast prokaryotes (bacteria and cyanobacteria).

Answer 3

There are two types of cells: prokaryotic and eukaryotic. Prokaryotes are simple cells that do not have a nucleus. All eukaryotes have a nucleus and other membrane bound organelles. Plants, animals, fungi, and protists are all eukaryotes.
