Cell nucleus

single-celled or multicellular organism that contains a membrane bound nucleus. A eukaryotic cell has a nucleus that entraps the DNA unlike the prokaryotic cell that lets it be free. A prokaryote is also known as bacteria. The DNA roams freely inside of the cell. Eukaryotic cells are large meanwhile prokaryotic cells are much smaller. There are many differences about the prokaryotes and eukaryotes cells. The DNA replication of a eukaryotic cell would be two chains held together by H bonds. The…

The nucleolus which is also known as the brain of a cell, is the most significant part in the nucleus. It takes up about 25 percent of the nucleus and it is not surrounded by a membrane. Through a microscope, the nucleolus is a big dot in the middle of it. It can be found in an animal, plant, diploid, and eukaryotic cell. It was found in the eighteenth century but its function wasn’t discovered until the 1960s. The nucleolus lives in the nuclear matrix. Sadly, the nucleolus is one of the…

The sperm’s centrioles are absolutely essential for…

eukaryotes (Reece et al., 2014). Prokaryotes (meaning before nucleus) are put in two domains: Bacteria and Archea (Biology Department, 2015). Eukaryotes on the other hand, (which have nuclei), are in the Eukarya domain and encompass all other organisms such as plants, animals, fungi and protists (Biology Department, 2015). The most effective way to distinguish between classes comes from observations made about their structure. Prokaryotic cells are smaller than eukaryotic ones; the typical…

In the cell, you have a vast majority of organelles that perform as needed today to support it. These organelles must go by a certain way of processing each of its duties to keep it alive and healthy. It’s like an auto body factory. When one thing goes wrong it causes problems throughout the entire cell. This could cause major discrepancies and dysfunctions that would most likely cause the human body to shut down due to illness, sickness, disease or more severely, death. So it’s a must these…

and epithelial tissues. One of which is that both the connective and epithelial tissues have at least 2 layers. A similarity between the connective and epithelial tissues related to the organelles present and its functions is that they both have nucleus and mitochondria, so both need the production of energy to function and both contain genetic material. Also both the epithelial and connective tissues contain proteins which without they would be unstable and unable to function as they do. There…

Cells are very important because they are assumed to be the basics of life. There are two types of cells that exist: Prokaryotes and Eukaryotes. The interesting thing is that, even though the prokaryotes seem to be very different from the eukaryotes. For example, humans look very different from the bacteria, but they still do share some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane…

into cells is one feature that distinguishes living things from all other matter. The cell is the smallest unit of matter that can carry on all the processes of life. The three principles define cell theory: 1. All living things are composed of one or more cells. 2. Cells are the basic units of structure and function in an organism. 3. Cells come only from the replication of existing cells. Most cells are small Prokaryotic: 1-10 µm Eukaryotic: 10 - 100 µm (1 µm = .001 mm) Shape of cell: Cells…

biological cells. Cells are the biological building block for all life; all living organisms have cells also. Cells provide structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, while…

In a cell, all of the organelles are a necessary part of the whole. The nucleus is the brains of the cell. The nucleus is also where the DNA is located. DNA are the proteins that hold the genetic code necessary for the cell to replicate. The DNA replication takes place in the ribosomes, where the proteins are translated in order to be replicated. The plasma membrane covers the entire cell and oversees the flow of chemicals that come both in and out of the cell. The plasma membrane creates a…
