root hair cell

Question 1

what is the structure of the root hair cell?

Answer 1

it has an elongated protrusion, has a large and concentrated central vacuole, with large numbers of mitochondria, and an absence of chloroplasts

Question 2

what is the function of the root hair cell?

Answer 2

the protrusion allows for a larger surface area to volume ratio, which allowed for effective absorption of materials. the vacuole allows for a concentration gradient so more water molecules and dissolved mineral salts can enter the cell. mitochondria is needed for more energy to be released for active transport, and chloroplasts are unnecessary organelles
