“1. Identify the major similarities and differences between prokaryotic and eukaryotic cells. “ The distinction between prokaryotes and eukaryotes is considered to be the most important distinction among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA. The most fundamental difference is that eukaryotes do have "true" nuclei containing their DNA, whereas the genetic material in prokaryotes is not membrane-bound. “2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic cell? “ In Eukaryotic cells (e.g. animal and plant cells), the DNA is held within the nucleus. But in Prokaryotic cells (e.g. bacteria cells), the DNA floats around the cell freely as prokaryotic cells do not contain a 'true nucleus'. “3. Name three structures which provide support and protection in a eukaryotic cell. “ Cytoplasm contains molecules, ions, water, and every cell organelle, except the nucleus. The cell wall lies outside of the cell membrane of plants. Cell walls function to provide structure, support, and protection for plant cells. The nucleus acts like a safe. Within the confines of the nucleus lies the cell's DNA, protected within a nuclear membrane, also called the nuclear envelope, which is as tough as the membrane surrounding the entire cell.
