WebPlants use cell plate formation to build a cell wall in the middle of the cell to form two daughter cells using phragmoplasts made of microtubules and microfilaments. Depending on the species, cytokinesis occurs after both meiosis 1 and meiosis 2 or only after meiosis 2. Meiosis 1 – homologous chromosomes pair up and are then moved apart.

As the meiotic … WebIn meiosis I replicated, homologous chromosomes pair up, or synapse, during the pachytene stage of prophase I, line up in the middle of the cell during metaphase I, and separate during anaphase I. For this to happen the homologous chromosomes need to be brought together while they condense during prophase I.

WebThe microtubules move toward the middle of the cell and attach to one of the two fused homologous chromosomes. The microtubules attach at each chromosomes' kinetochores. With each member of the homologous pair attached to opposite poles of the cell, in the next phase, the microtubules can pull the homologous pair apart. Web4 okt. 2024 · Metaphase is a stage in eukaryotic cell division in which the chromosomes align on the metaphase plate in the middle of the cell. The stages of prophase and prometaphase come before metaphase. In those stages of cell division, the chromosomes are condensed, the spindle fibers form, and the nuclear envelope is broken down.
