Transport System in Organisms

What is the important of the transport system in organism ?

• Transport oxygen and nutrients to the body cell

• Transport waste products to the body cells

• Transport urea and mineral salts to the body cell

• Transport carbon dioxide and nutrients to the body cells

Complex organism like human ......................

• Do not have a specialised transport system

• Need a special transport system

Simple organisms such as unicellular organisms ......................

• Do not have a specialised transport system

• Need a special transport system

Simple organisms such as amoeba and paramecium are able to obtain oxygen and nutrients enter directly into cells via .....................process through the cell membrane

• Diffusion

• Respiration

• Photosynthesis

• Transpiration

Which statement is FALSE about functions of the transport system in organisms

• Transports substances needed by body and plant cells

• Eliminates carbon dioxide and other waste products from body cells

• Transports products of photosynthesis

• To carry out all life processes in organisms

Two examples of substances needed by cells during respiration are.....

• Carbon dioxide and glucose

• Oxygen and glucose

• Urea and amino acids

• Carbon monoxide and nitrogen

Which of the following has spesific transport system ?

• Mucor

• Fish

• Amoeba

• Yeast

Why do complex organisms need transport systems ?

• Diffusion does not occur in simple organisms

• Diffusion does not occur in complex organisms

• Simple organisms have a larger surface area to volume ratio

• Complex organisms have a smaller surface area to volume ratio

What happen if the transport system fails to eliminate the waste products from the cells ?

• Becomes poison to the cells

• Becomes nutrient to the cells

• Combine with the cells

• Digested in the stomach
