Question

why is transport of materials necessary in plants or in a animal? explain.

Answer 1

Bodies of organisms like plants and animals are complex and contain complex tissues.
Maintaining such large bodies require a good transport system to transport various nutrients

In plants this is necessary because plants are tall and so the minerals from water cannot reach to the leaves.

In animals the complex organ system provides the need for a transport system

Answer 2

Hii dear here is your answer.

Transport of materials is necessary in plants and animals because:-

i) Every cell needs a regular supply of          nutrients and oxygen to release energy through respiration. These nutrients and oxygen need to be transported to all the cells of the body, through a transport system, so that they can produce energy.

ii) Waste products generated by cells need to be transported to the excretory organs, because accumulation of these waste products causes harmful effects on the organism's body.
