Question

What are some examples of plant transport?

Answer 1

Transport of water and minerals absorbed by roots from the soil and organic food synthesized in green leaves are two main examples of plant transport.

Plant transport is mainly of 2 types:
1. Transport of water and minerals absorbed by rots from the soil.
2. Transport of organic food materials synthesized in green pars of the plant, mainly leaves.

1. Transport of water and minerals- Water is absorbed from the soil by roots mainly in root hair zone. Minerals, present dissolved in water in soil, are absorbed by the roots mainly in meristematic zone.

The mechanism of absorption of water is different from that of minerals. Water is absorbed by passive mechanism; whereas the minerals are absorbed by active mechanism.

Water and minerals absorbed by the root are transported to different parts of the plant through xylem.

1. Transport of organic food- Leaves containing chlorophyll are the main sites of synthesis of
   simple carbohydrates during photosynthesis. The carbohydrates synthesized in leaves and
   other green tissues are transported to roots and other non-green parts of the plant through
   phloem.
