1. Generally, prokaryotes, such as bacteria, does not have membrane-bounded organelles. Vacuoles are membrane-bounded organelles. The question is, why do bacteria are said to have vacuoles? Support your answer with scientific/information. 2. Are lysosomes present in plant cells? Explain your answer with scientific/information. 3. In your own words, explicitly describe/discuss the endomembrane system.
