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.
1. Which of the following is a specialized leaf?
A - topsoil - grassland
vessels conduct sugars - traechids conduct water

2. Explain how a guard cell opens and closes the stoma?
rain
mitochondria - chemiosmosis

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
