Term
Mitosis
Definition
A part of eukaryotic cell division during which the cell nucleu divides.
Term
Cytokinesis
Definition
Division of the cytoplasm to form two separate daughter cells.
Term
Asexual Reproduction
Definition
Process of reproducing involving a single parent that results in offspring that are genetically identicle to the parent.
Term
Asexual Reproductin
Definition
na
Term
DNA
Definition
An extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms.
Term
Chromatin
Definition
Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones.
Term
Centromere
Definition
region of a chromosome where two sister chromatids attach.
Term
Interphase
Definition
Period of the cell cycle between cell divisions.
Term
Prophase
Definition
First and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible.
Term
Metaphase
Definition
Phase of mitosis in which the chromosomes line up across the center of the cell.
Term
Anaphase
Definition
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell.
Term
Telophase
Definition
Phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin.
Term
Cell Plate
Definition
A plate that develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells.
Term
Binary Fission
Definition
Type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identicle daughter cells.
Term
Budding
Definition
A small, rounded outgrowth produced from a fungus spore or cell by a process of asexual reproduction, eventually separating from the parent cell as a new individual.
Term
Spore Formation
Definition
Couldn't find it anywhere.
Term
Regeneration
Definition
The restoration or new growth by an organism of organs, tissues, etc., that have been lost, removed, or injured.
Term
Vegetative Propagation
Definition
The ability of plants to reproduce without sexual reproduction, by producing new plants from existing vegetative structures.
