Please tell me. What is the difference between osmosis and active transport?

No the answer is active transport because osmosis refers to movement of water molecules from higher to lower concentration and thus it is not applicable the reverse way. Hence active transport (by means of using ATP) is how plants take in nutrients from the soil when the concentration is already high in their root cells.

I think the answer is osmosis because, it also has same features.

As active transport why don't you consider this as a answer please clarify my doubt.

Since osmosis and active are movement of a substance from low to high what is the different?

What is the lightest metal?

Whats the difference between diffusion and passive transport ?

Osmosis is also movement from low concentration to high then what is difference between osmosis and active transport?

Explain ceoleterate

Active transport is the movement of a substance against its concentration gradient (from low to high concentration). In all cells, this is usually concerned with accumulating high concentrations of molecules that the cell needs, such as ions, glucose, and amino acids. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed primary active transport. Secondary active transport involves the use of an electrochemical gradient. Active transport uses energy, unlike passive transport, which does not use any type of energy. Active transport is a good example of a process for which cells require energy. Examples of active transport include the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plants.

Is it like this that the cells move against concentration gradient or the solute or solvent moves against the concentration gradient ? the active transport requires energy which is not mentioned in the question ?.
