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...

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...

Meristems - Plant tissue that remains embryonic as long as the plant lives, allowing for indeterminate growth. Ground tissue and it's three cell types - the tissue between the dermal tissue and vascular tissue of a non-woody plant that functions in photosynthesis, storage, and support. parenchyma, collenchyma, and sclerenchyma Monocot cross section - Monocot cross section Suberin - Fatty material found in the cell walls of cork tissue and in the Casparian strip of the endodermis that a...

Describe how tissue fluid is formed and how it is returned to the circulatory system. - Answer Formation 1. High blood / hydrostatic pressure / pressure filtration; 2. Forces water / fluid out; 3. Large proteins remain in capillary; Return 4. Low water potential in capillary / blood; 5. Due to (plasma) proteins; 6. Water enters capillary / blood; 7. (By) osmosis; 8. Correct reference to lymph; Describe how carbon dioxide in the air outside a leaf reaches mesophyll cells insid...

Why are cations difficult to get access to in the soil? - They are difficult because they bond tightly to the soil so another cation has to come break their bond Clay is negatively charged and tightly bind to cations making it difficult to uptake from soil 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 make sugar for the plant What are the two key tissues...
