In which of the following yam tissues will osmosis occur?
Answer Details
Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration through a semi-permeable membrane. In the context of yam tissues, osmosis will occur in those tissues that are separated from their environment by a semi-permeable membrane.
Out of the given options, the tissues that are most likely to undergo osmosis are the raw and peeled yam tissues. This is because the raw yam tissues have intact cell membranes which act as semi-permeable membranes, allowing the movement of water molecules in and out of the cells through osmosis. Additionally, peeling the yam removes the waxy cuticle layer which further enhances the permeability of the cell membrane to water molecules.
On the other hand, boiling and roasting alter the cell structure of the yam tissues, making them less likely to undergo osmosis. Boiling and roasting cause the cell walls to rupture and lose their semi-permeable nature, which makes it difficult for water molecules to move in and out of the cells through osmosis.
In summary, osmosis is most likely to occur in the raw and peeled yam tissues, as they have intact cell membranes that act as semi-permeable membranes. The boiled and unpeeled yam tissues may also undergo osmosis, but to a lesser extent due to the alteration of the cell walls caused by boiling. The roasted and peeled yam tissues are the least likely to undergo osmosis due to the complete alteration of the cell structure caused by roasting.
