Cellular Basis of Reproduction and Inheritance

Nuclear division process that halves the chromosome number. basis of sexual reproduction

Nuclear division mechanism that maintains the chromosome number. basis of body growth, tissue repair and replacement in multicelled eukaryotes; also asexual reproduction in some plants, animals, fungi, and protists.

A series of events from the time a cell forms until its cytoplasm divides

Refers to the two members of a pair of chromosomes with the same length, shape, and genes

In a eukaryotic cell cycle, the interval between mitotic divisions when a cell grows, roughly doubles the number of its cytoplasmic components, and replicates its DNA

Stage of mitosis in which sister chromatids separate and move to opposite spindle poles

Stage of mitosis during which the cell's chromosomes align midway between poles of the spindle

Stage of mitosis in which chromosomes condense and become attached to a newly forming spindle

Dynamically assembled and disassembled array of microtubules that moves chromosomes during nuclear division

Stage of mitosis during which chromosomes arrive at the spindle poles and decondense, and new nuclei form

Reproductive mode by which offspring arise from one parent and inherit that parent's genes only

After nuclear division in a plant cell, a disk-shaped structure that forms a cross-wall between the two new nuclei

In a dividing animal cell, the indentation where cytoplasmic division will occur

A genetically identical copy of an organism

A thin band of actin and myosin filaments that wraps around the midsection of an animal cell. during cytoplasmic division, the band contracts and pinches the cytoplasm in two
