Translocation of water and nutrients takes place in plant body
Answers
The plant body is generally divided into roots, stem, and leaves. The roots are in the soil, which is the major source of nutrients in plants. Water and other nutrients enter the plant through the roots. The leaves are the food production centres. Using the sunlight and Carbon dioxide they synthesize food through photosynthesis in the chloroplasts.
Now, food from the leaves has to reach the other parts and the water, along with other nutrients has to reach leaves and other parts. All of this takes place through the vascular tissues of the plants. This is basically the transportation in plants.
You have already learned in earlier classes about the specialized cells and tissues in plants, which are the xylem and phloem. Together, they constitute the vascular structure in plants
Translocation is the movement of materials in plants from the leaves to other parts of the plant. Nutrients, mainly sugars, are created in the leaves during photosynthesis. ... This causes sugar to build up in the phloem in the leaves, and water enters via osmosis.
