diffusion
What is another process using diffusion
eliminating waste products
Do unicellular organisms have a specialized transport system
No
Substances needed by cell such as oxygen and nutrients enter diffusions through
cell membrane
Example of complex multicellular organisms
human , vertebrate and multicellular
Do complex organisms have specialized transport system
yes
Why do complex organism have specialized transport system
Large surface area
What is the transport system known as ?
Blood circularity system
State the three importance of the function of transport organisms
-Carries substances needed by cells such as oxygen and nutrients that are used to produce energy
-Eliminates toxic waste
-needed by plant , cells such as mineral salt water and products of photosynthesis + carry out process in plants
