Four Organelles Used In Eukaryotic Organisms

409 Words2 Pages

Four organelles that should be present in the eukaryotic organism are the nucleus, mitochondria, chloroplasts, and ribosomes. The nucleus stores genetic information/DNA. The mitochondria acts like a digestive system and it’s where cellular respiration occurs. The chloroplast converts light energy into sugars, which is used by cells, this is the process of photosynthesis. The ribosome is the site of protein synthesis.

There is no nucleus in prokaryotic cells, the DNA just floats around, but in eukaryotic cells the DNA is located in the nucleus. In eukaryotes the mitochondria is a digestive system where cellular respiration or ATP synthesis occurs. But in prokaryotic cells, other membranes function in ATP synthesis. In eukaryotes, chloroplasts convert light energy into sugars, but in prokaryotic cells, other membranes/cytosolic molecules absorb light and do photosynthesis. …show more content…

This theory states that a range of prokaryotic cells were the first organisms that existed on earth. Those prokaryotes ate other prokaryotes, so large heterotrophic cells consumed smaller cells. Then, a symbiotic relationship was formed between the two cells and the small cell developed into the mitochondria and chloroplast. Finally, a nuclear envelope outlined the DNA.

Photosynthesis and cellular respiration play an important role in the carbon cycle. All living things are made up of carbon, so carbon is everywhere. Plants need carbon dioxide to flourish and make sugars. When cellular respiration lets out CO2, photosynthesis removes CO2 out of the atmosphere. This keeps the oxygen and the CO2 in the atmosphere at a balanced level. Organelles that are involved in this process are the chloroplast and mitochondria. The reactants of photosynthesis are the products of cellular respiration. The products of photosynthesis are the reactants of cellular
