b) How do the structure of a root hair cell is related to its functions in transporting substances?
……the surface area of the root hair cell allows it to absorb water and
nutrients from the soil
……………………………………………………………………………………………… ……[2]
c) Why do red blood cells not have a nucleus, and how does that help them carry out their
function?
Because they carry oxygen, so this helps them carry more oxygen

experiment…………………………………………………………………………………………
………………………………………………………………………………………..…………………
…… [2]
f) If you make a hypothesis about something (e.g., "Plants grow better with more sunlight"),
how could you test it with an experiment?
……you take two plants that are the same then put one in a shade
with no sign of the sun ( put it at room temperature) and then the
other one outside in the presence of the sun then leave them for 1 or
