Active Transport

Question 1

What is active transport

Answer 1

Movement of substances against a concentration gradient (from an area of low concentration to high concentration)

Question 2

How does active transport work when minerals are being absorbed by root hairs

Answer 2

The plant roots grow into hairs into the soil
Each branch is covered in hairs, increasing the surface area for absorption
The concentration of the minerals is usually higher in the root hair cells than in the soil

Question 3

What do plants need minerals for

Answer 3

Healthy growth

Question 4

What does active transport need to work

Answer 4

Energy from respiration

Question 5

Where is active transport used in the body
