    between animal and plant cells. Although plant and animal cells both have mitochondria‚ cytoplasm‚ and ribosomes they differ in many ways. Animal cells do not have a cell wall and are round with irregular shapes. Centrioles are also present in all animal cells‚ as well as most eukaryotic cells. Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles‚ but their functions are quite different. The purpose of vacuoles in a plant cell is to store water and

    revealed a molecular mechanism that directs the chance and role of cells during the process of animal development. The researchers’ discovery shows remarkable findings that are promising in the advancement of cancer and stem-cell research. The hypothesis of this article relates to even though each individual cell contains the complete DNA code‚ only small portions of this DNA code are activated. Therefore‚ the cell has a certain function instead of others. Every single gene in the DNA code is accountable
