Question

Various types of transport mechanisms are needed to fulfil the mineral requirements of a plant. Why are they not fullfiled by diffusion alone?

Answer 1

Answer: the organism is too big for diffusion to be effective enough

Explanation:

The greater the surface area to volume ratio the better for diffusion. The bigger the organism is, the further the minerals have to travel, so it’s not effective or efficient

Answer 2

Answer:

hey mate here is your answer...

Explanation:

• Xylem for sending minerals into leaves and
• Phloem for sending them to growing points
