a certain plant's roots contain higher concentration of nitrate than the soil that surrounds them. Which of the fallowing mechanism explains the movement of nitrate from soil into the plant's roots? Active transport???
Yes.
Thank you !!!!!!!!
Well, well, well! Look who's digging into science now! Nitrogen compounds can be quite a "root-ine" choice for plants. So, to answer your question - yes, active transport is indeed one possible mechanism for the movement of nitrate from soil into a plant's roots!
You see, active transport is like the VIP express lane for nutrients. It requires energy, usually in the form of ATP, for the plant to actively pump those nitrate goodies against the concentration gradient, from an area of lower concentration in the soil to an area of higher concentration in the roots. It's like the plant is saying, "Move over, passive diffusion! I'm going in!"
So, it's kind of like the plant is flexing its botanical muscles to snatch those nitrate ions, all so it can grow big and strong. I guess you could say plants have a real thirst for nitrogen. It's their way of "root-ing" for success in their nutrient uptake. Way to grow, little plant!
Yes, active transport is the mechanism that explains the movement of nitrate from the soil into the plant's roots. Active transport involves the use of energy to transport molecules or ions across a cell membrane against their concentration gradient. In this case, the plant root cells actively transport nitrate ions from the soil, where their concentration is lower, into the roots, where their concentration is higher. This ensures that the plant can take up the necessary nutrients from the soil.
Yes, active transport is the mechanism that explains the movement of nitrate from the soil into the plant's roots when the roots contain a higher concentration of nitrate than the surrounding soil.
To understand active transport, you need to know that it is a process that requires energy expenditure by the plant to move substances, such as nitrate ions, against their concentration gradient—meaning from an area of lower concentration to an area of higher concentration.
In the case of the plant's roots, when there is a higher concentration of nitrate inside the roots compared to the soil, active transport comes into play. The plant uses energy, typically in the form of ATP (adenosine triphosphate), to actively transport nitrate ions across the plasma membrane of root cells. This process allows the plant to absorb and accumulate nitrate ions against the concentration gradient into the root cells, leading to a higher concentration of nitrate within the roots.
In summary, active transport is the mechanism utilized by plants to move nitrate ions into their roots when the concentration of nitrate is higher inside the roots compared to the surrounding soil.
