From your knowledge of the size and density of cell components and the process of centrifugation, predict the order (from first to last) that the nucleus and organelles will be extracted?
a.ribosomes-mitochondria and chloroplasts-nucleus-soluble cytoplasm
b.nucleus-mitochondria and chloroplasts-ribosomes-soluble cytoplasm
c.nucleus-mitochondria and chloroplasts-soluble cytoplasm-ribosomes
d.mitochondria and chloroplasts-nucleus-soluble cytoplasm-ribosomes
e.soluble cytoplasm-ribosomes-mitochondria and chloroplasts-nucleus
B. nucleus mitochondria and chloroplast ribosomes-soluble cytopasm
Well, isn't this a centrifugation conundrum! Let me think...
Hmm, based on the size and density of cell components and the process of centrifugation, I would predict that the correct order would be:
b. nucleus-mitochondria and chloroplasts-ribosomes-soluble cytoplasm
See, the nucleus is typically the largest and densest component, followed by mitochondria and chloroplasts. Ribosomes and soluble cytoplasm would come after.
So, if you're planning to extract these components, remember to start with the nucleus and then get those mitochondria, chloroplasts, ribosomes, and finish it off with the soluble cytoplasm. Happy centrifuging!
Based on the size and density of cell components and the process of centrifugation, the correct order (from first to last) that the nucleus and organelles will be extracted is:
b. nucleus-mitochondria and chloroplasts-ribosomes-soluble cytoplasm
To predict the order in which the nucleus and organelles will be extracted using centrifugation, we need to consider both the size and density of the cell components.
Centrifugation involves spinning a mixture at high speeds, causing the components to separate based on their size and density. Heavier and denser components settle to the bottom first, while lighter and less dense components settle last.
Based on this information, we can make some predictions:
- The nucleus is typically a large and dense organelle, so it will settle towards the bottom and be extracted early on.
- Ribosomes are small and less dense compared to the other organelles, so they will settle towards the top and be extracted later.
- Mitochondria and chloroplasts are relatively larger organelles and have some density, so they will settle between the nucleus and ribosomes.
- Soluble cytoplasm refers to the fluid portion of the cell, which does not have a specific size or density. It will remain in the supernatant after centrifugation.
Considering these predictions, the correct order would be:
b. nucleus-mitochondria and chloroplasts-ribosomes-soluble cytoplasm
