Well, I dont think they had model numbers back then but I will look on the web for what microscopes where used. I found something but it doesnt say anything about a model of microscope! Here is the fact. <span>The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead </span>cell walls of plant cells (cork) as it appeared under the microscope. This was taken from google, I hope this helps? Here is the link : http://bitesizebio.com/166/history-of-cell-biology/
That would be 2.
They are both very specific in their actions and only bind to particular molecules.
Hope this helps:)
Hi! What are the possible answers?
Answer:
Mitochondria originated when an ameoba like organism engulfed an aerobic proteobacterium capable of cellular respiration.
Explanation:
Endosymbiotic Theory:
- The endosymbiotic theory explains the origin of eukaryotic cells and eukaryotic organelles, particularly the chloroplast and mitochondria.
- According to this theory, a prokaryotic ameoba like organism increased in size and gradually developed infoldings of its plasma membrane. These infoldings gradually developed into an endomembrane that enclosed the genetic material and nucleus.
- This cell then engulfed a proteobacterium capable of cellular respiration. Over time, this cell thrived as oxygen increased in the atmosphere of the Earth. The proteobacterium survived as an endosymbiont and later evolved into mitochondria.
