The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

plants in dry land and mammalian cells in aqueous surrounding because of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels;

vital organs of the body that need them for sustenance. Eventually without the ability to produce ATP the body’s cells will die. C. Which intracellular organelles have membranes as part of their structure? How would the breakdown of the membranes of these structures affect the function of Joseph’s heart cells? Every intracellular organelle has membranes‚ with ATPase’s transferring calcium from the cytosol to the endoplasmic reticulum in cardiac muscle cells. Without the membrane the levels would

Chloroplasts are the food makers of the cell. The organelles are only found in plant cells and in algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The process is called photosynthesis and it all depends on the green chlorophyll in each chloroplast. Chloroplasts are round about 4 to 6 micrometres in diameter. Russian botanist Konstantin Mereschkowsky was the first person to discover the chloroplast. He discovered

FRQ #4 The endomembrane system is made up of different membranes that are suspended in the cytoplasm within a cell. These membranes divide the cell into functional and structural compartments‚ or organelles. The endomembrane system has three major components; the plasma membrane‚ Golgi apparatus‚ and vesicles. The plasma membrane surrounds the outside of the cell. It is made up of a double layer of phospholipids and controls the movement of various substances into and out of the cell‚ both passively
