.
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. As best as you can - briefly describe the development of vascular tissue by the lateral/vascular cambium of a stem and how that results in the production of wood?

18. Explain the process by which plants get water from the soil into the leaves?
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

phloem
deciduous

22. Why do most roots tend to die in soils that contain very high concentrations of salts (or fertilizer)?
exocarp
penicilin
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
phloem
23. A plant with flowers containing stamens but no carpels would be a ___ plant with ____ flowers?
into the cell
