Active Transport

Question 1

Active transport

Answer 1

The movement of molecules against the concentration gradient

Lower concentration to higher concentration

It happens in the cell membrane

Needs special proteins
It also needs respiration

Question 2

Where is active transport used example:

Answer 2

In plants (that need to absorb a lot of water)

The problem is their is a higher concentration inside the cell then outside the cell so diffusion can’t be used. So active transport has to be used from cellular respiration such as mitchondria

Question 3

What is root hair cell for and how are they adapted

Answer 3

Absorbing mineral ions and water

They are adapted by having long hair like protrusions which gives it a large surface area
