mammals. 3) Slide 3: Why is the nucleus of the cell in slide 3 so large? In other words‚ what is this cell doing that requires that its nucleus be so large? (Please be specific). In eukaryotic cell in slide #3 has organelles including a nucleus containing DNA and mitochondria energy organelles .Compared to the prokaryotic cell which has the DNA in the cytoplasm smaller and simpler and doesn’t contain a nucleus or other organelles‚ it does have cell membrane. Bacteria and Archea are single celled

Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

1. You are looking at a neuron under a microscope. You find many structures coming off the cell body. Some of these are relatively thick and branch many times. One of the structures‚ however‚ is very thin and very long. This latter structure is most likely the neuron’s __________ ‚ which carries the __________. a. dendrite; efferent signal b. dendrite; afferent signal c. axon; action potential d. axon; receptors 2. If the myelin sheathing on neurons is absent or removed in a given individual

Cells are some of the smallest organisms around. All living things consist of cells‚ and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly. All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane

Cell Theory In biology‚ cell theory is a scientific theory that describes the properties of cells‚ the basic unit of structure in every living thing. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells‚ and that the cell is a fundamental unit of structure‚ function and organization in all living organisms. It is one of the
