2 New Identical Cells

4 gamete cells

no Mem-bound organelles or nucleus, small. mostly bacteriaesque

organelles, big (10-1000uM), plants and animals

researchers use these in experiments. rapid reproduction, short gestation, short maturity period, large number of offspring, easy maintenance, high genome knowledge. often related to human genome

cells contained in a culture

removing tissue of an organism to create a primary cell culture. is direct, but limited cell count

finite number of cells, won’t divide further. usually in triplicate

indefinite number, continues to divide. ABNORMAL, but infinite. found in Cancer cells, Embryo Blastocysts, and adult bone marrow stem cells.

made of Inner Cell Mass, becomes most of the embryo. cells divide, and are considered stem cells.

visualize objects and structures in cells with magnification and resolution enhancement

light is the source of energy for the magnification and resolution.

lowest resolution, general shape of cell shown. usually fixed cells

second lowest resolution, displays shape and some density of object.

more precise resolution, caused by exciting cells with Fluo. light to create emissions from the object. shows general indication of cell structure

best light microscopy resolution, uses pinpoints of light (similar to pointillism) and scans of different planes to make an image with depth

Attach a tracer during translation to mark the desired cell portion.
