1.Chromatin is the DNA and proteins that make up a chromosome. Chromosomes are the separate pieces of DNA in a cell. And Chromatids are identical pieces of DNA held together by a centromere. ... Histone- they help condense chromatin and DNA into Chromatin.
2.Cell membrane is present is all cells while cell wall is only present in plants, bacteria, fungi and algae. 2. Cell wall is made up of cellulose whereas cell membrane is made up of lipids and proteins. ... Cell wall is non-living whereas cell membrane is living.
3.Nucleus is the main organelle while nucleolus is the sub organelle of nucleus. ... Nucleus is membrane bound while nucleolus is non membranous bound.
4.Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
