!!!!!!!!!!!!!!Bacteria 算唔算living cell?(10點!!!!!!!!!!!!!!!!!)

I think bacteria is living cell. it is unicellular and it contain genetic information in form od circular DNA. It can carry out respiration and can reproduce by binary fission. It has normal cell activity. So bacteria is a unicellular organism, a living cell

Not all cell have mitochondria. for example, red blood cell don't have mitchondria.

據我bio ga 知識...
organism 裡面有分five kingdoms ga 其中
而其中一門 就係prokaryote (原核生物 e.g cholera )
bacteria 係屬於prokaryote ga 一種
所以我諗應該係living cell

而線粒體...唔係每個cell 都有...就好似red blood cell


希望岩...!!!
