The importance of transport in living organisms

1. The importance of transport in living organisms

You will:
- explain the importance of transport of nutrients in
living organisms.

2.

• Nutrient is a chemical or food which is needed to living organism.
• Nutrients are used for energy production, growth, and reproduction.

3.

• A single-celled organism (unicellular) does not need a transport
system because they take nutrients from environment by whole body

4.

• Unicellular organisms have large surface area compared to their
volume.

5.

• Large multicellular organisms have small surface areas compared to
their volumes.
• So, they need a special transport system

6. Plant organs

Leaf
Stem
Root
Flower
Fruit

7.

• Xylem transports
water from the root
to the leaves.
• Phloem transports
organic molecules
(sugar), from leaves,
to different parts of
the plant.
