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.
1. Roots differ from stems in ___?

2. A primary function of traechids is ___?
to open - potassium will enter the guard cell. then the guard cell will swell and attract water to the stomata - or area of high concentration. Once the plant has enough water - potassium will diffuse out - the guard cells will shrink - and finally c

23. A uniovulate carpel would contain how many seed?
vessels
1

24. Why do most roots tend to die in soils that contain very high concentrations of salts (or fertilizer)?
conduction and absorption
water molecules are split - through the energy of light - into hydrogen ions - electrons - and oxygen
node
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
25. Most of the flesh of pomes comes from the __?

stele
vascular bundles
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.
