Question
How is food transported from phloem to the tissues according to plants’ needs?(a) food is transported along with the water in the plant’s body.(b)food is transported in only one direction like water in the plant body through xylem.(c) food is transported from a region with low concentration to higher concentration.(d)food is transported from a region where it is produced to other parts of the plants.
Solution
The correct answer is (d) food is transported from a region where it is produced to other parts of the plants.
Here's the step by step process:
-
Photosynthesis: The process of food production in plants begins with photosynthesis in the leaves. Here, sunlight, water, and carbon dioxide are used to produce glucose (food) and oxygen.
-
Loading into Phloem: The glucose produced is then loaded into the phloem tissue. This is done by active transport, where energy is used to move the glucose against a concentration gradient into the sieve tubes of the phloem.
-
Translocation: Once in the phloem, the food can be transported to other parts of the plant where it is needed. This process is called translocation. It is not a simple process and can move in any direction - up, down, sideways - depending on where the food is needed.
-
Unloading from Phloem: When the food reaches the part of the plant where it is needed, it is unloaded from the phloem and used. This could be a growing root or shoot, a developing fruit, or a storage organ like a tuber.
So, the food is not transported along with water in the plant's body (option a is incorrect), it is not transported in only one direction like water in the plant body through xylem (option b is incorrect), and it is not transported from a region with low concentration to higher concentration (option c is incorrect).
