.
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 is a type of epidermal cell?
guard cell and root hair
into the cell
vascular bundles
ovary
2. Explain the process by which plants get water from the soil into the leaves?
loam
glycolysis
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
