the size of cheek cell and onion cell DCP: Introduction: In this experiment‚ Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell. Hypothesis: The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which is to maintain

Chemical Composition of Cells Testing for Proteins: The independent variable is the biuret reagent. The dependent variable is the solutions being used as follows; distilled water‚ albumin solution‚ and starch solution. If the protein is present‚ then the biuret will change to a violet color. Authors: Eliza Koundry and Jody Cote Eliza was in charge of adding equal amounts of biuret reagent to the distilled water‚ albumin solution‚ and the starch solution. Jody was

Cellulitis: Cellulitis is a common skin infection caused by bacteria. Causes Staphylococcus and streptococcus bacteria are the most common causes of cellulitis. The skin normally has many types of bacteria living on it. When there is a break in the skin‚ however‚ bacteria can enter the body and cause infection and inflammation. The skin tissues in the infected area become red‚ hot‚ irritated‚ and painful. Risk factors for cellulitis include: • Cracks or peeling skin between the

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury to them. All cells grow and die at different rates. The cell cycle can be divided into three periods: interphase‚ the mitotic phase‚ and cytokinesis. During interphase‚ the cell grows‚ accumulating nutrients needed for mitosis‚ preparing it for cell division and duplicating its DNA. During the mitotic phase‚ the cell splits itself into two distinct daughter

Animal cells do not have a cell wall. Instead of a cell wall‚ the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Animal tissues therefore require either external or internal support from some kind of skeleton. Frameworks of rigid cellulose fibrils thicken and strengthen the cell walls of higher plants. Plasmodesmata that connect the protoplasts of higher plant cells do not have a counterpart in the animal cell model. During telophase
