Read the passage given below and answer the four questions from [11] to [15]. |
All living organisms need some method of moving substances from one part of the body to other parts of the body. Plants have a transport system to move things around. |
The xylem moves water and solutes from roots to leaves through transpiration. The phloem moves glucose and amino acids from the leaves to all parts of the plant through translocation. |
In modern plants, the xylem and phloem are arranged in groups called vascular bundles. The xylem is constituted by 4 elements, i.e. tracheids, vessels, parenchyma and fibres, while phloem is constituted by sieve tubes, companion cells, phloem fibres and parenchyma. |
