Alveolate

The alveolates (meaning "with cavities") are a group of protists, considered a major clade and superphylum within Eukarya, and are also called Alveolata.

Bacteria

Bacteria (common noun bacteria, singular bacterium) is a type of biological cell.

Blepharisma japonicum

Blepharisma japonicum is a species of protozoan that can be found either in water or soil in Japan.

Cell cycle

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.

Cell membrane

The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space).

Ciliate

The ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella.

Colpidium colpoda

Colpidium colpoda are free-living ciliates commonly found in many freshwater environments including streams, rivers, lakes and ponds across the world.

Contractile vacuole

A contractile vacuole (CV) is a sub-cellular structure (organelle) involved in osmoregulation.

Eukaryote

Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike Prokaryotes (Bacteria and other Archaea).

Fission (biology)

Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original.

Flagellate

A flagellate is a cell or organism with one or more whip-like appendages called flagella.

Genus

A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology.

Heterotrich

The heterotrichs are a class of ciliates.

Isogamy

Isogamy is a form of sexual reproduction that involves gametes of similar morphology (similar shape and size), differing in general only in allele expression in one or more mating-type regions. Because both gametes look alike, they cannot be classified as "male" or "female". Instead, organisms undergoing isogamy are said to have different mating types, most commonly noted as "+" and "−" strains, although in some species of Basidiomycota there are more than two mating types (designated by numbers or letters). In all cases, fertilization occurs when gametes of two different mating types fuse to form a zygote.

Macronucleus

A macronucleus (formerly also meganucleus) is the larger type of nucleus in ciliates.

New!!: Blepharisma and Macronucleus · See more »

Meiosis

Meiosis (from Greek μείωσις, meiosis, which means lessening) is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.

Membranelle

Membranelles (also membranellae) are structures found around the mouth, or cytostome, in ciliates.

New!!: Blepharisma and Membranelle · See more »

Micronucleus

Micronucleus is the name given to the small nucleus that forms whenever a chromosome or a fragment of a chromosome is not incorporated into one of the daughter nuclei during cell division.

New!!: Blepharisma and Micronucleus · See more »

Model organism

A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms.

Outcrossing

Out-crossing or out-breeding means that the crossing between different breeds.This is the practice of introducing unrelated genetic material into a breeding line.

Peristome

Peristome (from the Greek peri, meaning 'around' or 'about', and stoma, 'mouth') is an anatomical feature that surrounds an opening to an organ or structure.

New!!: Blepharisma and Peristome · See more »

Ploidy

Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.

New!!: Blepharisma and Ploidy · See more »

Protist

A protist is any eukaryotic organism that has cells with nuclei and is not an animal, plant or fungus.

New!!: Blepharisma and Protist · See more »

Rotifer

The rotifers (Rotifera, commonly called wheel animals) make up a phylum of microscopic and near-microscopic pseudocoelomate animals.

SAR supergroup

Sar or Harosa (informally the SAR supergroup) is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria.

Selfing

Selfing or self-fertilization is the union of male and female gametes and/or nuclei from same haploid, diploid, or polyploid organism.

New!!: Blepharisma and Selfing · See more »

Sexual reproduction

Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm.

New!!: Blepharisma and Sexual reproduction · See more »

Type species

In zoological nomenclature, a type species (species typica) is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s).

Unicellular organism

A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell.

New!!: Blepharisma and Unicellular organism · See more »

Vegetative reproduction

Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or vegetative cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure.
