Transport
Biology · 50 practice questions
Need for and materials of transportation; the mammalian circulatory system (heart, arteries, veins, capillaries) and the plant vascular system (phloem, xylem); media and mechanisms of transportation.
- Determine the relationship between increase in size/complexity and the need for a transport system.
- Describe the circulatory system and compare the functions of major blood vessels.
- Identify plant vascular organs and their functions.
- Describe diffusion, osmosis, plasmolysis and turgidity, and compare transpiration pull, root pressure and active transport as transport mechanisms in plants.
Try a few questions
- Practice question 1
The heart, within the mammalian circulatory system, specifically functions mainly as a
- A.muscular pump driving the circulation of blood
- B.storage organ that holds digested food prior to its absorption
- C.a factor entirely unrelated to a muscular pump driving blood circulation
- D.filter that removes waste products directly from the blood
Show the answer
A. muscular pump driving the circulation of blood
The heart, within the mammalian circulatory system, specifically functions mainly as a muscular pump driving blood circulation.
- Practice question 2
Platelets, found in mammalian blood, specifically function mainly in
- A.the clotting of blood at the site of a wound
- B.the defence of the body against infection, a function instead of white blood cells
- C.the transport of oxygen around the body, a function instead of red blood cells
- D.a factor entirely unrelated to the clotting of blood of any kind
Show the answer
A. the clotting of blood at the site of a wound
Platelets, found in mammalian blood, specifically function mainly in the clotting of blood at the site of a wound.
- Practice question 3
The transpiration stream specifically describes the overall pathway of water movement from the
- A.leaf directly to the root, in a reversal of the typical direction of flow
- B.a factor entirely unrelated to the pathway of water from root to leaf
- C.phloem exclusively, bypassing the xylem at every stage of the pathway
- D.root, through the xylem, to the leaf, where it is eventually lost as vapour
Show the answer
D. root, through the xylem, to the leaf, where it is eventually lost as vapour
The transpiration stream specifically describes the pathway of water movement from the root, through the xylem, to the leaf.
