active transport in root hair cells

Question 1

what is active transport?

Answer 1

the movement of particles through a membrane against the concentration gradient (low to high conc) which requires energy from cellular respiration

Question 2

what stores energy released from cellular respiration and what is its other function?

Answer 2

ATP takes energy released from cellular respiration to other parts of the cell

Question 3

what is the purpose of root hair cells?

Answer 3

to take minerals and water from the soil into the plant

Question 4

why do root hair cells need to carry out active transport?

Answer 4

they need to take minerals from the soil where they are in lower concentration so to take them in would be against the concentration gradient

Question 5

how are root hair cells adapted to carry out their function?

Answer 5

they have long hair-like protrusions and lots of mitochondria

Question 6

how does having long hair-like protrusions help root hair cells carry out their function?

Answer 6

gives them a larger surface area for absorption

Question 7

how does having lots of mitochondria help root hair cells carry out their function?

Answer 7

lots of mitochondria carry out cellular respiration and give them the energy for active transport
