Vesicles are used to ship materials around, into, and out of the cell. Cell membranes can pinch off in places to form vesicles, as can lysosome membranes and golgi membranes. Because mitochondria and chloroplasts are practically tiny cells within cells, I wouldn't be surprised if they had their own vesicles. If you're asking literally which organelles have vesicles inside them, I'd say the mitochondria and chloroplasts, possibly Golgi (depends on your instructor), but the cell membrane, lysosomes, and golgi can definitely make vesicles. The rough ER uses vesicles but I wouldn't consider the vesicles a part of the ER.
N and P limitation is strongest in aquatic ecosystems (because
light and water isn't) governed by same principles as terrestrial ecosystems radically
different environmental controls streams have been treated as "sewers of
terrestrial ecosystems" yet stream ecosystems have their own
characteristics generated by the interaction of biota with the physical and chemical
properties of the system unlike terrestrial ecosystems, nutrients
"spiral" rather than cycle. The more limiting the nutrient, the
tighter the spiral. Detritus/heterotrophs <---> autotrophs.
Answer:
first question:The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms
:second question: The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.
