What is the difference between a cellular organelle and a cellular inclusion?

Question

Also, why would a celery stalk become soft and limpy if placed in salty water? (something do to with hypertonic and hypotonic)

Answer 1

1. A cellular organelle is a membrane-bound structure inside the cell, each kind of organelle having a different function. Examples of cellular organelles are mitochondria, chloroplasts, vacuoles, Golgi bodies, ... A cellular inclusion is a foreign particle or a metabolically inactive substance inside the cell. Examples of cellular inclusions are fat droplets, lead, viruses, ....
2. Salt water is hypertonic for celery stalks. More water goes out of the cells of the celery than the amount of water that goes in. So the water pressure inside the cell decreases and the stalk becomes limp. In a hypertonic solution, there is a higher concentration of solutes and a lower concentration of water when compared with the cell's cytoplasm. I teach my students that hyperRRRRtonic solutions make the inside of the cell shRRRRRRink. HypOOOOO tonic solutions make the inside of the cell swell up like an "O". ISSSSSSotonic solutions keep the cells the SSSSSSame. Exaggerate the sounds and it will stick in your mind.
