Active Transport

Question 1

Why do plants mineral ions ?

Answer 1

Plants need mineral ions so that they can grow healthy

Question 2

How do root hairs take in minerals ?

Answer 2

Root hairs take in minerals by using the active transport

Question 3

What does the active transport allow the plant to do ?

Answer 3

The active transport allows plants to absorb minerals from a very dilute solution, against a concentration gradient.

This is essential for its growth. But active transport needs energy from respiration to make it work

Question 4

Where is active transport used in humans ?

Answer 4

Active transport is used in the gut when there is a lower concentration of nutrients in the gut, but a higher concentration of nutrients in the blood

Question 5

When there is a higher concentration of glucose and amino acids what happens ?

Answer 5

When there’s a higher concentration of glucose and amino acids in the gut they diffuse naturally into the blood

BUT sometimes there’s a lower concentration of nutrients in the gut than there is in the blood. This means that the concentration gradient is the wrong way

Question 6

Where does active transport allow nutrients to be taken into ?

Answer 6

Active transport allows nutrients to be taken into the blood, despite the fact that the concentration gradient is the wrong way
