<p>1.If ribosome is made up of RNA and proteins. and proteins are made from ribosome. so which organelle made the protein for ribosome?
2. when,for example, sugar was decomposed by enzyme, where does the product go? does it go through nucleus or not?</p>
<p>thx for the help!!!</p>
<p>oh, one more question. Is the plant cell structure tested on Ap test?</p>
<p>
Yes, indeed. Plant, Animal, Prokaryote, if it's a cell, it's tested.

I'm not exactly sure what you're asking, but there are already ribosomes in the cell to make new proteins for new ribosomes.

I have no idea what you are asking here.</p>
<p>The nucleolus makes ribosomes, though your question is confusing.</p>
<p>And #2 is vague too, what do you mean? You mean like glucose? Because that goes through a whole process (cell respiration). The products are ATP, which are used by cells or stored, water, and CO2. The water and CO2 are breathed out or eliminated from the organism (at least in more complex eukaryotes).</p>
<p>Waste products might also be removed by budding a vesicle (that contains the waste products) off of the cell.</p>
