.
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.

stolon/runner
sweet potato
axillary bud
ovary
20. Leaves and buds are attached to the stem at the ___?
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
node
desert
vascular cambium
21. Which is a type of epidermal cell?
water conduction
guard cell and root hair
cortex
node
22. Explain how a guard cell opens and closes the stoma?
A - topsoil - grassland
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
