A mango tree has about m² of leaves. On a sunny day, each square metre of leaf loses about L of water by transpiration. How much water does the tree lose in a day, and in a week of sunny days? How many L buckets would replace the loss of the week?
Need a reminder? The key ideaShow
Xylem carries water and minerals up from the roots. Root pressure pushes water up, mostly at night. In the day, transpiration from the leaves pulls water up the xylem. Phloem carries food (sucrose) to where it is needed, up or down, using energy from ATP. This is translocation.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. One day. .
Step 2. One week. .
Step 3. Buckets. , so buckets are needed.
Answer: L a day, L a week, and buckets.
