.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

22. Why do most roots tend to die in soils that contain very high concentrations of salts (or fertilizer)?
exocarp
If there is a higher concentration of salts outside of the root - then water will not move inside the roots against the concentration gradient. the roots will dehydrate and eventually die

casperian strips
transpiration
prickles
stigma
24. ____ is the stage of cellular respiration that takes place outside of the mitochondria?
vascular bundles
glycolysis
grows back every year
the root hairs on the root tips absorb water into the soil through osmosis. this water travels up the roots - up the stems - and to the leaves throughout the plant by capillary action. once absored in leaves - the water leaves the plant through trans
25. Root hairs are found in the region of the root called the ____?
penicilin
pericarp
potassium
region of maturation
26. In a mature - woody dicot stem - the tissue between the xylem and phloem is the ____?
cambium
1
cassava
all of the above are correct
27. Differentiate between diffusion and osmosis?
red light
penicilin
the vascular cambium produces both secondary xylem and secondary phloem - or vascular tissue. The secondary xylem is the wood in dicot plant and lignon surrounds it for support.
diffusion is the movement of particles from high to low concentration; osmosis is movement of water from high to low concentration
