In plants, food is transported through

Detailed Solution for Olympiad Test: Transportation in Animals & Plants - Question 8
Transportation of Food in Plants
Food is transported in plants through the phloem, which is a complex tissue responsible for the translocation of sugars, amino acids, and other organic compounds throughout the plant.
Here is a detailed explanation of how food is transported through the phloem:
1. Structure of Phloem:
- The phloem consists of sieve elements, companion cells, phloem parenchyma, and phloem fibers.
- The primary conducting cells in the phloem are the sieve elements, which are connected end-to-end to form sieve tubes.
2. Process of Translocation:
- Photosynthesis occurs in the leaves, where food (sugars) is produced.
- The sugars are transported from the source (leaves) to the sink (other parts of the plant, such as roots, fruits, or growing tissues) through the phloem.
- The movement of sugars in the phloem is called translocation.
3. Pressure Flow Hypothesis:
- According to the pressure flow hypothesis, sugars are actively loaded into sieve elements of the phloem at the source.
- This loading process creates a high concentration of sugars in the phloem, resulting in osmotic pressure.
- The osmotic pressure drives the movement of sugars from the source to the sink.
- At the sink, the sugars are actively unloaded from the phloem.
4. Mechanism of Translocation:
- The movement of sugars in the phloem is facilitated by companion cells, which are connected to the sieve elements by plasmodesmata.
- Companion cells provide energy and metabolic support for the sieve elements.
- The sugars move through the sieve tubes via mass flow, driven by the pressure gradient created by the osmotic pressure.
- This mass flow allows for efficient and rapid transport of food throughout the plant.
In conclusion, food in plants is transported through the phloem, which is a complex tissue responsible for the translocation of sugars and other organic compounds. The pressure flow hypothesis explains how sugars are loaded, transported, and unloaded in the phloem, allowing for efficient distribution of nutrients to different parts of the plant.
