Correct option is B
The Correct Answer Is: (b) It transports sugar
Explanation:
Phloem is a type of vascular tissue in plants responsible for the transport of sugars (mainly in the form of sucrose) and other organic compounds from the leaves (where they are produced during photosynthesis) to other parts of the plant, including the roots, stems, and fruits.
Phloem is a type of vascular tissue in plants responsible for the transport of sugars (mainly in the form of sucrose) and other organic compounds from the leaves (where they are produced during photosynthesis) to other parts of the plant, including the roots, stems, and fruits.
This process is known as translocation. Unlike xylem, which carries water and minerals, phloem primarily carries the products of photosynthesis, which are crucial for growth and energy storage in plants.
Phloem consists of several types of cells, including sieve tube elements, companion cells, phloem fibers, and phloem parenchyma, which work together to transport nutrients efficiently.
Information Booster:
- Translocation of Sugars: The movement of sugars from source (leaves) to sink (roots, stems, fruits) is facilitated by the phloem, ensuring the plant gets the energy it needs for growth and reproduction.
- Phloem Structure: The sieve tube elements form long tubes that are connected end to end, allowing easy movement of substances. Companion cells assist in the functioning of sieve tube elements.
- Role in Plant Growth: Phloem is crucial for the transport of not only sugars but also amino acids, hormones, and other organic compounds.
- Direction of Flow: Phloem transports sugars and other substances downwards from leaves and upwards from roots depending on the plant's needs.
- Xylem vs Phloem: While xylem primarily transports water and minerals, phloem is mainly responsible for the transport of sugars and other organic materials.
Additional Information:
- It transports water: The xylem tissue is responsible for the transport of water.
- It transports oxygen: Oxygen is transported through air and water in plants.
- It transports carbon dioxide: Carbon dioxide enters plants through stomata and is used in photosynthesis.
