Answer (1)
To compare the plant and animal transport systems, we can fill in the table with the following information:
Feature/Function
Main transport structures
Plant Transport System : The main structures are the xylem and phloem. Xylem transports water and minerals from roots to other parts of the plant, while phloem distributes sugars and organic nutrients produced during photosynthesis.
Animal Transport System : The main structure is the circulatory system, which includes the heart, blood, and blood vessels such as arteries, veins, and capillaries.
Materials transported
Plant Transport System : Mainly water, minerals, and nutrients (like sugars).
Animal Transport System : Blood circulates oxygen, carbon dioxide, nutrients, hormones, and waste products.
Driving force of movement
Plant Transport System : Transpiration pull (evaporation of water from leaves), root pressure, and osmotic pressure drive the movement of materials.
Animal Transport System : The heart pumps blood through the circulatory system, creating pressure that drives movement.
Presence of a pump (heart)
Plant Transport System : There is no pump like a heart in plants.
Animal Transport System : Yes, there is a heart that acts as a pump.
Direction of flow
Plant Transport System : Unidirectional in xylem (roots to leaves) and bidirectional in phloem (leaves to other parts, and vice versa).
Animal Transport System : The circulatory system is mostly a closed loop, with blood flowing from the heart to the body and back to the heart, allowing a continuous, cyclic flow.
