Transport in Plants 2

Why do unicellular organisms not require a transport system?

• They have tiny bodies thus very small body volumes

• They have a large surface area to volume ratio

• Most of their body is in contact with their surrounding

• All of the above

Roots have 2 main functions, absorption of water and mineral salts and
