After a family picnic,Ella dumped the ice and rock salt from ice cream maker in the back yard.that area of yard now contains dead,brown grass. Explain why this happened using word plasmolysis in your explanation.
Ah, poor Ella, unintentionally wreaking havoc on the yard with her ice cream maker adventures! Well, let me break it down for you using some humor and a sprinkle of science:
You see, when Ella dumped that icy mess on the yard, it caused a phenomenon known as plasmolysis (cue the scientific spotlight!). Plasmolysis is like the yard's own little drama queen – it occurs when water moves out of the grass cells due to a higher concentration of dissolved substances outside the cells. It's basically a case of "water, why are you leaving me?"
Now, in this frosty debacle, the rock salt played the role of the villain. It's a sneaky substance that loves to mess with water balance. As rock salt started dissolving in the water, it created a high concentration of dissolved substances outside the grass cells. When the concentration of these substances becomes higher than inside the cells, water molecules start to leave the cells, thinking, "Hey, maybe it's time for a change of scenery!"
As a result of this water exodus, the grass cells become deprived of their much-needed fluid support. And voila! The grass starts to turn brown and lifeless, like it's auditioning for a role in an emo band. The poor things just couldn't handle the sudden loss of water and nutrients.
So remember, kids, when you're dealing with icy leftovers from ice cream making adventures, make sure you dispose of them responsibly. Otherwise, your yard might throw a temper tantrum in the form of plasmolysis, leaving you with a sad, brown lawn.
The dead, brown grass in the area of the yard where Ella dumped the ice and rock salt from the ice cream maker can be explained through the process of plasmolysis. Plasmolysis occurs when a plant cell loses water and the cell membrane pulls away from the cell wall.
In this case, the rock salt dumped by Ella likely caused a high concentration of salt in the soil. When the ice melted, the water absorbed the salt and, due to osmosis, water moved out of the plant cells towards the area of higher solute concentration (the salt in the soil). As a result, the plant cells started losing water, leading to plasmolysis.
As the plant cells lost water, the cell membranes pulled away from the cell walls, causing the grass to wither and turn brown. The lack of water in the plant cells hinders their normal functions, such as photosynthesis, which is crucial for the production of chlorophyll and the plant's green color. Consequently, the affected grass in that area of the yard turned brown and died due to the excessive salt concentration and plasmolysis.
Plasmolysis is a process that occurs in plant cells when there is a loss of water from the cell due to an external osmotic imbalance. In this case, when Ella dumped the ice and rock salt from the ice cream maker in the backyard, it created a high concentration of salt in that specific area.
The salt acts as an osmotic agent, drawing water out of the plant cells through osmosis. Osmosis is the movement of water from an area of lower solute concentration (inside the plant cells) to an area of higher solute concentration (outside the cells in the soil). As a result, the water molecules within the plant cells move outwards to dilute the high salt concentration in the soil.
Plants require water for various physiological processes, including maintaining turgidity, transporting nutrients, and carrying out photosynthesis. When water is lost from the plant cells, they become dehydrated and shrink. This shrinkage of the cell membrane away from the cell wall is known as plasmolysis.
As the plant cells lose water due to the high salt concentration in the soil, the cells become dehydrated and shrink. The loss of water causes the plant cells to lose their turgidity, making them unable to perform their normal functions. Consequently, the affected area of the yard experiences dead and brown grass, as the plant cells are unable to carry out photosynthesis properly and sustain themselves.
In summary, the high salt concentration created by dumping the ice and rock salt in the backyard led to plasmolysis in the plant cells, causing them to lose water and resulting in dead, brown grass.
