B1: Active Transport

Question 1

active transport

Answer 1

active transport moves substances from an area of low to high concentration against the concentration gradient and required energy

Question 2

what does active transport require?

Answer 2

requires energy from respiration

as it takes a lot of energy to move against a concentration gradient

Question 3

root hair cells

Answer 3

the concentration of minerals is usually higher in the root hair cells than the soil around them therefore active transport must take place

Question 4

active transport in root hair cells

Answer 4

active transport allows the plant to absorb minerals from an area of low concentration to an area of high concentration. This is essential for its growth. Root hair cells have a lot of mitochondria for this.
