Final answer:
Segregative cell division in Cladophorales refers to the process where cellular contents are divided to form two separate daughter cells during cytokinesis, ensuring each new cell receives a complete set of genetic material.
Step-by-step explanation:
The term Segregative cell division describes a cellular division where a cell divides and separates its cellular contents to form two distinct daughter cells. This mode of division occurs in the Cladophorales, a group of green algae. In cytokinesis, typical in eukaryotic cells, the cytoplasm is split, and either a cleavage furrow (in animal cells) or a cell plate (in plant cells) that will develop into a cell wall is used to separate the daughter cells.
During the process of cell division, duplicated chromosomes are segregated into two new nuclei. Following this, cytokinesis ensues, partitioning the parent cell's cytoplasm into two daughter cells. This division ensures that each daughter cell has a full set of genetic material.
