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.

In plants, the transport system is not as ....... as in animals.
