Question
Observe water transport in plant roots: Recall that the vascular tissue that moves water throughout a plant is called A)_________, which pulls water into the plant through its B) __________ when water loss (called C) __________) through stomata produces tension along a whole chain of water molecules. Using wilted celery as your model system, come up with a way to demontrate (1) the cohesion-tension model of water flow through a plant, (2) osmotic flow of water from the vascular tissue to surrounding plant cells, (3) where the water flow occurs in the plant stem and (4) whether celery is a monocot or eudicot. Describe your method and results.Recall that the other type of vascular tissue is called D)__________, and its direction of transport is from the plan't E)___________ (where the chemical reaction called F)__________ is producing the carbohydrate called G)________) all the way to its H)__________.
If a plant such as honeysuckle produces nectar in a flower in order to feed pollinators, which vessel type do you think supplies this to the flower? I)___________. Why?J)______________
Explanation / Answer
A) There are 2 types of vascular tissue: xylem and phloem. Xylem carries water and minerals while Phloem carries nutrients/food. (answer to D as well) B) Tracheids are the important part of the xylem that carry the water. C) water loss for a plant is also known as transpiration D) refer to (A) E) if you use the hint of F first, you can see that the reaction of F takes place in the leaves. More specifically, phloem vessels are made up of sieve tube elements and companion cells. F) Photosynthesis converts light, co2 and h2o into sugar and oxygen. G) the carbohydrate that F produces is c6h12o6. It's a sugar, aka glucose H) This is the destination of the nutrients which are also included in the leaves. I and J) Nectar is more considered nutrients (rather than water) so it would be transported through the Phloem more.
