1/3/15 Animal Cell There are two types of cells that exist. Prokaryotic cells are simple cells that have few organelles. These cells don’t have a nucleus‚ but do have DNA. The DNA acts as a sort of “blueprint” for growth and reproduction in the cell. Prokaryotes are things like Bacteria. Eukaryotic cells are a lot more complex than a prokaryotic cell. These cells are able to convert food to energy‚ break down waste products‚ digest food‚ and assist with reproduction of new cells. Eukaryotic

Animal Cell Cells are the beginning of everything. Every living thing is composed and made from cells. Cells are the smallest unit of organization that we know of. There are two major categories of cellular organization in eukaryotic cells. Those parts which are “membrane bound”‚ called organelles and those which are not “membrane bound”. Every aspect of the cell is important because each part or organelle’s structure is unique to its function. Non membrane bound organelles‚ are those which provide

The division of opinion on cloning will require many forums of discussion to cover all aspects. There are serval types of cloning‚ Reproductive‚ therapeutic and DNA cloning. Any animal created by reproductive cloning is not in fact a perfectly matching copy of its donor. Reproductive cloning involves generating an animal that has the same nuclear
