Eukaryote
16 linksEukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Eukaryotes may be either unicellular or multicellular, and include many cell types forming different kinds of tissue; in comparison, prokaryotes are typically unicellular.
Cell (biology)
11 linksBasic structural and functional unit of life forms.
Basic structural and functional unit of life forms.
Organisms can be classified as unicellular (consisting of a single cell such as bacteria) or multicellular (including plants and animals).
Algae
10 linksInformal term for a large and diverse group of photosynthetic eukaryotic organisms.
Informal term for a large and diverse group of photosynthetic eukaryotic organisms.
Included organisms range from unicellular microalgae, such as Chlorella, Prototheca and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length.
Organism
8 linksOrganism is any organic, living system that functions as an individual entity.
Organism is any organic, living system that functions as an individual entity.
Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea.
Unicellular organism
8 linksA unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells.
Fungus
7 linksAny member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.
Growth of fungi as multicellular structures consisting of somatic and reproductive cells—a feature independently evolved in animals and plants —has several functions, including the development of fruit bodies for dissemination of sexual spores (see above) and biofilms for substrate colonization and intercellular communication.
Cell division
6 linksProcess by which a parent cell divides, when a mother cell divides into two or more daughter cells.
Process by which a parent cell divides, when a mother cell divides into two or more daughter cells.
On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings.
Red algae
3 linksRed algae, or Rhodophyta, are one of the oldest groups of eukaryotic algae.
Red algae, or Rhodophyta, are one of the oldest groups of eukaryotic algae.
The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds.
Protozoa
6 linksInformal term for a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris.
Informal term for a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris.
Originally, the group included not only single-celled microorganisms but also some "lower" multicellular animals, such as rotifers, corals, sponges, jellyfish, bryozoa and polychaete worms.
