Astudent has obtained a sample of pond water for study. using the high-power lens, he observes several cells with nuclei. he can conclude that the cells are not bacteria.
true/false

True

Explanation:

Bacteria are prokaryotic organisms. Being prokaryotes, bacteria do not have a nucleus in their cells. Their DNA or the genetic material lies in the cytoplasm itself. Therefore, if the observed cells have a nucleus and other membrane-bound organelles, this means that those cells were not the bacterial cells. Bacterial cells also do not have other membrane-bound organelles such as mitochondria, endoplasmic reticulum, etc.
