Term
mitosis
Definition
is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei
Term
cytokinesis
Definition
is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.
Term
asexual reproduction
Definition
is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only, it is reproduction which does not involve meiosis, ploidy reduction, or fertilization.
Term
Dna
Definition
A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.
Term
Chromatin
Definition
is the combination of DNA, histone, and other proteins that make up chromosomes
Term
Centromere
Definition
is a region of DNA typically found near the middle of a chromosome where two identical sister chromatids come closest in contact
Term
Interphase
Definition
is the phase of the cell cycle in which the cell spends the majority of its time and performs the majority of its purposes including preparation for cell division
Term
prophase
Definition
The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.
Term
Metaphase
Definition
The stage of mitosis and meiosis, following prophase and preceding anaphase, during which the chromosomes are aligned along the metaphase plate.
Term
anaphase
Definition
is the stage of mitosis when chromosomes separate in an eukaryotic cell.
Term
telophase
Definition
is a stage in both meiosis and mitosis in a eukaryotic cell. During telophase, the effects of prophase and prometaphase events are reversed.
Term
Cell plate
Definition
A partition formed during cell division in plants and some algae that separates the two newly formed daughter cells.
Term
binary fission
Definition
is the subdivision of a body, population, or species into parts and the regeneration of those parts into separate individuals.
Term
budding
Definition
is a form of asexual reproduction in which a new organism grows on each other. The new organism remains attached as it grows, separating from the parent organism only when it is mature.
Term
Spore Formation
Definition
A mode of reproduction resembling multiple fission, common among Protozoa, in which the organism breaks up into a number of pieces, or spores, each of which eventually develops into an organism like the parent form
Term
Regeneration
Definition
is the process of renewal, restoration, and growth that makes genomes, cells, organs, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans
Term
Vegatative Propagation
Definition
Production of a new plant from a portion of another plant, such as a stem or bran
