active uptake

Question 1

how are root hair cells adapted

Answer 1

long hairs to absorb minerals
finger like extension for absorbing minerals
many mitochoria

Question 2

why do cells have to use active transport

Answer 2

because it needs energy to power it

Question 3

whats the problem with the minerals in the root hair cells

Answer 3

the concentration of minerals is to high so the minerals cant move from diffusion

Question 4

how do the cells need to do to take in nitrates

Answer 4

they have to take it against the concentration gradient low to high

Question 5

if the soil has plenty of oxygen what happens

Answer 5

the root hairs can carry out aerobic respiration and make plently of energy
they can carry out active uptake and move the minerals into the cells against the concentration gradient

Question 5

if the soil is flooded what happens

Answer 5

the airspaces in the soil are filled with water
therefore there no oxygen in the soil
the root hair cells cant carry out aerobic respiration
they cant make much energy or carry out active uptake
they dont make minerals
cant make protein for growth
they die or grow poorly

Question 5

why do plants need active transport

Answer 5

the concentration of minerals inside the cell is higher than outside the cells so the minerals cant move by diffusion
