Chromatin interphase

Webchromatin: [noun] a complex chiefly of DNA and histone in eukaryotic cells that is usually dispersed in the interphase nucleus and condensed into chromosomes in mitosis and … WebIn plant cells, the first part of mitosis is the same as in animal cells. (Interphase, Prophase, Metaphase, Anaphase, Telophase). Then, where an animal cell would go through cytokineses, a plant cell simply creates a new cell plate in the middle, creating two new cells. The cell plate later changes to a cell wall once the division is complete.
