Document Summary
Eukaryotic cells have internal membranes that compartmentalize their. The big oily blob moved around circular objects, chasing the small black dots. (chase= movement) The big blob consumed the smaller black dots, but the small dots were trying to run away. Oily blob= eukaryotic cell (human cell and phagocytic cell, white blood cell) Cell membrane (semi- permeable): it engulfs certain things only, by recognition. Cytoskeleton: gives cell shape and structure to move. Lysosome: digest bacteria after it has been internalized. Nucleus: not directly involved in the engulfing, but it can lead the structure and the cellular components to do this. Single eukaryotic and prokaryotic cells are capable of directed movement. White blood cell can recognize the bacteria and distinguish other cells types (red blood cell 0. Light microscopy allows to see live specimens and their movement but cannot resolve subcellular structures. All cells are bounded by a selective barrier, called the plasma membrane.
