Cell Reproduction

Cell Reproduction. Chapter 8. Chromosomes = rod-shaped structures made of DNA and proteins. Histone = protein that helps maintain the shape of chromosomes and aid in the tight packing of DNA. Chromatid = each half of the chromosome, exact copies that have been replicated.

Differences

Differences. Plant: Plant cell mitosis is similar to animal cell mitosis, but there are differences. Plant cells form spindle fibers during mitosis but do not have centrioles . A structure called a cell plate forms between the two new nuclei.
