Question
Plants absorb minerals from the soil by the process known as ___________.
Question 11
Answer
- a. active transport
- b. diffusion
- c. exocytosis
- d. osmosis
Solution
Plants absorb minerals from the soil by the process known as active transport.
Here's a step-by-step explanation:
-
Minerals in the soil are essential for plant growth and development. These include macronutrients like nitrogen, phosphorus, and potassium, as well as micronutrients like iron, zinc, and copper.
-
These minerals are usually found in the soil in the form of ions, which are charged particles.
-
The roots of the plant absorb these mineral ions from the soil. However, the concentration of these ions is often lower in the soil than it is inside the plant cells.
-
Therefore, to absorb these ions, the plant must move them from an area of lower concentration in the soil to an area of higher concentration in the plant cells. This requires energy and is done through a process called active transport.
-
Active transport involves specific transport proteins in the cell membrane of the root cells. These proteins bind to the mineral ions and use energy to move them into the cell.
So, the correct answer is a. active transport.
