Transportation in plants important points: Transportation in the plants refers to movement of water, minerals, and organic substances from the roots to the leaves, and from the leaves to the other parts of the plant. It occurs through the specialized structures known as xylem and phloem.
Xylem is responsible for transportation of water and minerals from the roots to the rest of the plant, while the phloem is responsible for transportation of the organic substances like the sugar and the amino acids of a protein. This process is crucial for plant’s growth and survival.

There are 25 important points on transportation in plants
1. Transportation of water and minerals from the roots to the leaves.
2. Transportation of the photosynthetic products from the leaves to other parts of the plant.
3. Transpiration pull: when water moves from the roots to the leaves through the stem.
4. Role of the xylem is water transportation.
5. Role of the phloem is the transportation of organic compounds.
6. Importance of the root pressure is water movement.
7. Importance of the transpiration in the overall water balance of the plant.
8. Importance of the osmosis in transportation of water across cell membranes
9. Active transport of minerals against concentration gradient
