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

Ribosome Pigs Ribosomes produce proteins when given raw material just like pigs produce protein when they are fed Golgi Apparatus Farmer’s wife The farmer’s wife can turn small things (wool‚ food ingredients‚ seeds‚ etc) and turn it into something bigger and better (blanket‚ meals‚ garden‚ etc). The golgi does the same‚ except with molecules and atoms. Mitochondria Windmill Windmills generate power. Mitochondria

plant supplies electricity to the entire town. Power plants are enclosed by the building walls and a fence for protection‚ such as a double membrane. It is also divided into many floors‚ such as the interior of the Mitochondria. Golgi Apparatus- The Golgi Apparatus stacks and packages protein. Once this protein is packaged‚ vesicles pinch off‚ which will allow it to be opened to the exterior through exocytosis. It transports the goods created in the Endoplasmic Reticulum and ribosome to the rest

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS All mammalian cells are eukaryotic‚ and whilst the eukaryotic type of cell is not exclusive to mammals‚ mammalian cells differ from other eukaryotic cells because of the organelles that are or are not present. For instance some plant cells have chloroplasts which are not present in mammalian cells‚ but both plant cells and mammalian cells are eukaryotic in nature. The term eukaryotic refers

Labeled Plant Cell Plant Cell Organelles Amyloplast A major component of plants that are starchy in nature‚ the amyloplast are organelles that store starch. They are classified as plastids‚ and are also known as starch grains. They are responsible for the conversion of starch into sugar‚ that gives the starchy plants and tubers energy. Function: Synthesis and storage of starch granules Cell Membrane or Plasma Membrane The cell membrane is a thin layer made up of proteins‚ lipids‚ and

Cell Structure I. Cell History A. Anton Leewenhock (1600s) - first person to observe cells - in pond water‚ using a homemade microscope B. Robert Hooke (1665) - observed many kinds of animal tissue under a microscope - concludes that all animals are made up of cells C. Schwann (1868) - observed many kinds of animal tissue - concludes that all animals are made up of cells D. Schleiden (1869) - observed many kinds of plant tissue - concludes that all plants are made up of cells E. Cell

The main organs of the CNS is the brain‚ spinal cord‚ and nerves. These organs mostly consist of Nervous Tissues. http://www.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/19588.jpg Nervous Tissues Nervous tissues are made up of two main types of cells: nerve cells/neurons and neuroglia.

Artificial Sweeteners 1. Artificial sweeteners are a sugar substance that is a food additive that duplicates the effect of sugar taste‚ usually with less food energy. 2. No‚ it is possible that these artificial sweeteners can change the way we taste food‚ over stimulation of sugar receptors from frequent use of these hyper-intense sweeteners may limit tolerance for more complex tastes. 3. No‚ food processors should be allowed to put them in food because they do not give much energy. Also‚ food
