What did you say for the functions of xylem and the insert question I said. I said transports water and transports mineral ions. And for the function, I talked about spiral lignin and non lignified pits

The grade boundaries are always mega low for bio anyway compared to chem or physics, like 60% for an A*. This year they'll be somewhere between 2019 and 2021 boundaries

will i get the marks if i said lignin for high tensile strength to support the stem, then pits to allow water through for a continuous flow up the xylem?? i forgot to mention the pits prevent pathogens from entering
