He made his first microscope in the 1670s, using a single, high-quality lens that he ground himself. This allowed him to see objects that were too small to be seen with the naked eye, including bacteria, yeast cells, and sperm cells.]]> 2023-03-09 12:23:08 UTC https://padlet.com/vicentesanmartin2/nxmxkm6b2i7y48hb/wish/2510195122 vicentesanmartin2 https://padlet.com/vicentesanmartin2/nxmxkm6b2i7y48hb/wish/2510195396 1838, proposed that all plant tissues are made up of cells.

He proposed that cells divide and give rise to new cells, which then go on to divide themselves. This process of cell division is now known as the cell cycle, and it is a fundamental aspect of how living organisms grow and reproduce.]]> 2023-03-09 12:24:09 UTC https://padlet.com/vicentesanmartin2/nxmxkm6b2i7y48hb/wish/2510196467 vicentesanmartin2 https://padlet.com/vicentesanmartin2/nxmxkm6b2i7y48hb/wish/2510196995 Studied mitosis chromatin preparations, using genetic material from the fins and gills of salamanders as the only source.
