Xylem Study guides, Class notes & Summaries

What are xylem? - Answer Tubes that carry water and mineral ions in solution; water travels upwards from roots to leaves. They are formed from dead cells. How is water transported in the xylem? - Answer THE COHESION-TENSION THEORY: 1)Water evaporates from the leaves- transpiration. 2)This creats tension which pulls more water into the leaf. 3)Water molecules are cohesive so the whole column of water moves upwards. 4)Water enters the stem via the roots. What is transpiration? - An...

4 major plant parts include - roots stems leaves reproductive parts 4 functions of the root system include - absorption anchorage conduction storage 2 kind of root systems found in plants are - fibrous root systems and taproot systems Fibrous root system - root system that consists of numerous multi-branched roots that are slender; no one root is more prominent than the other. Tap root system (more difficult to transplant) - root system that consists of one main root that gro...

I achieved a high A* Grade in my final A-Level exams using these notes!!! I believe you can achieve an A* if you can memorise these notes! Simply use blurting, a method of active recall, to write everything you remember from the notes, then identify the parts you couldn’t remember, then repeat until you can remember it all! If you can do that, you’ve got an A* in the bag! They are clear, concise, and are laid out according to the specification; there is no information missing or in excess...

What are the two key tissues that allow plants to transport water or organic nutrients, respectively, over long distances? - Xylem - water and minerals from roots to shoots . Phloem - transports sugars from photosynthesis to where they are needed In the root, plants need to take up more CO2 or O2? - More O2 Is the need for CO2 and O2 in leaves the same when compared to roots? - The difference is because of what the plant needs at that certain spot. The CO2 is needed for photosynthesis to ma...
