Cell Biology An Introduction Of The Cell - 2034 Words

Cell Biology An introduction to the cell The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell, which are categorized according to the way their genetic material is packaged, rather than size or shape. These are: 1. Prokaryote cells - bacteria and archeans. They are single celled organisms, where the DNA is not separate from the cytoplasm. These prokaryote cells formed the earliest and most primitive life on earth. 2. Eukaryotic cells - found in animals, plants and fungi. In eukaryotic cells, the DNA is sectioned off from the cytoplasm in its own membrane compartment called the nucleus. Cells share many common features but have adapted over billions of years in a wide array of environments, to provide a variety of functional roles. The structures and functions of a cell. In order for cells and organisms to â€Å"live† they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

An example of a prokaryotic cell is bacteria. A Eukaryotic Cell does have a membrane-bound nucleus, making it different from a Prokaryotic Cell. The Nucleus contains genetic material and is surrounded by a nuclear envelope. An example is an animal cell. Both types of cells containRead MoreReport on School Science Fair631 Words   |  3 Pagesweek Introduction This report investigates an activity done during the activity week which took place during the third week in June 2014. The science fair was held during the fourth day and this programme was initiated to demonstrate science related experiments to the students. The experiments were based on form 5 and form 4 practical books. The science fair was conducted by teachers from science department and was divided into three different subjects; physics, chemistry and biology. The objectivesRead MoreStudent Application Essay1742 Words   |  7 Pagesteams of as many as three interns in research projects. I am primary or co-author of five peer-reviewed research papers and have presented at more than ten major conferences in the field of biomedical sciences, including International Society of Stem Cell Research conference. As a biomedical scientist with nine years of research and two years of teaching experiences, and passion for serving academic community, I am well positioned to make Wellesley grow and to contribute to Wellesley’s mission of buildingRead MoreWhy Is Plant Cells?1750 Words   |  7 PagesWhy is it that plant cells are autotrophic whereas animal cells are not? The answer is simple; chloroplasts. These are green organelles that are the main site for photosynthesis in plant cells. They allow the plant to be known as the ‘producer’ in a food chain. Being such an essential part of the plant cell, the question arises, where e xactly did they come from in the first place. Have they been a part of the plant cells since the beginning of time or did they evolve from some other species, andRead MoreThe Effect Of Acid Concentrations Increases Permeability Of Beetroot ( ,Äà © Beta Vulgaris ) Cell Membranes1488 Words   |  6 Pagespermeability of beetroot (‎Beta vulgaris) cell membranes indicated through color intensity using the spectrophotometer Joshua Elekwa Introduction to cell Biology, Fall 2014 Mount Royal University ABSTRACT The cell membrane (Plasma membrane) functions to provide cell support, cell stability and control entry and exit of materials from the cell. This study was conducted to test the effects of environmental conditions such as the on beet root cell membrane (Beta vulgaris).

Bacteria is the more numerous type of prokaryotes. The group hypothesizes that the samples taken from different environments will all cultivate diverse morphology in fast growing rates in each environment. The aseptic technique was used to cultivate bacteria from different environments.
