What were the demerits of cell theory???
Answers
Limitations of the Cell Theory:
-Muscles are elongated cells, which contain several nucleuses in one cell in order to control it (multi-nucleoid)
-Viruses: living or not? Cells or not?
-Fungal hyphae: acquires a continual cytoplasm, very large and multi-nucleoid.
Louis Pasteur made a nutrient broth by boiling water containing yeast and sugar. He concluded that the germs in the air were able to fall unobstructed down the straight-necked flask and contaminate the broth. The other flask which had the “swan-neck”, trapped germs in its curved neck, preventing them from reaching the broth, which never changed color or became cloudy. This explains that spontaneous generation was not a real phenomenon since; the broth in the curved-neck flask would have eventually become re-infected because the germs would have spontaneously generated. But the curved-neck flask never became infected, indicating that the germs could only come from other germs.
