Cell plate cytokinesis is a type of cell division that occurs in plant cells, where a new cell wall is formed to separate two daughter cells. This process occurs during the later stages of cell division, specifically during telophase and cytokinesis.

During the process of cell division in plant cells, the spindle fibers pull the chromosomes towards opposite poles of the cell, and a new cell wall needs to be formed to separate the two daughter cells. However, since plant cells have a cell wall...

The stage of cell division in which paired homologous chromosomes get shortened and thickened is prophase I of meiosis. During this stage, the chromosomes condense and become visible as distinct structures, allowing for the homologous chromosomes to pair up and exchange genetic material through a process called crossing over. The shortening and thickening of the chromosomes during prophase I is important for proper alignment and separation of the homologous chromosomes during subsequent...

During the S-phase of interphase, DNA replication takes place within the entangled chromatin fibers. As a result of DNA replication, each chromosome in the cell is composed of two identical sister chromatids held together at the centromere.

During prophase of mitosis, the chromatin fibers condense and become visible as thick, distinct chromosomes. This condensation is necessary to ensure that the replicated chromosomes can be separated correctly during cell division. At this stage, the sister...
