Biology Notes about Microscopes, Scientists, and Cells.

Microscopes were invented in the 1600s. Robert Hooke primary looked at a thin fade of cork in 1665; he saw a dish out of little boxes. These little boxes first reminded of the little rooms monks lived in, so he c wholeed them booths. Hooke observed the similar pattern in the stems and stemma of carrots and other plants. What Hooke still did non know, nevertheless, was that kiosks be the basic units of nutriment things. Ten classs later, the Dutch scientist Anton train Leeuwenhoek focused a microscope on what seemed to be clear consortium water and discovered a wondrous world of lifetime creatures. He named the tiny animals animalcules. It took scientists some(prenominal) than 150 yrs. to waxy prize the discoveries of Hooke and Leeuwenhoek. In 1838, the German plant scientist Matthias Schleiden concluded that mobile phoneular phones compose non alone the stems and roots however every part of a plant. A year later, the German zoologist Theodor Shwann made the a homogeneous(p) claim about animals. And in 1858, a German physician Rudolph Virchow observed that mobile phones come completely from other cells. The observations of Shleiden, Shwann, and Virchow form what is know today as the cell theory. The cell theory is say in three scat: 1. in all living things argon peaceful of one or to a greater extent cells. 2.In organisms, cells are the basic units of structure and function. 3.Cells are produced only from be cells. All cells, still those that are very simple, all share real characteristics. All cells allow a cell membrane or plasma membrane, which separates the cells contents from materials outside the cell. The cell membrane likewise determines what goes in and out of the cell, helping to state homeostasis.

Without the cell membrane, the cell would die, because it would untie the substances it needs to maintain life. All cells take hold a... These are close to beautiful darn meticulous notes.
