The Latin name is from the Japanese name for T. sieboldii. T. canadensis and T. heterophylla were discovered early (before 1800) and until 1855 were simply treated as species of Pinus, but in 1842 T. sieboldii, the southern Japanese hemlock, was described as Abies tsugae.
The brains of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.
Plant cells contain some organelles not found in animal cells, such as cell walls and chloroplasts. Each organelle has specific functions in the life and health of the cell, and cell health is important for the well-being of the entire organism.lso called the Golgi complex or Golgi body, this organelle looks like a stack of flattened water balloons. It processes the proteins produced by the endoplasmic reticulum and ribosomes, modifying and storing them until it packages them in vesicles. Lysosomes also come from the Golgi apparatus.
