Make a table to compare xylem and phloem.
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
Make a table to compare xylem and phloem. Use four points: what each carries, the direction, the main cells, and whether the cells are alive.
Need a reminder? The key ideaShow
Xylem carries water and minerals up, and is mostly dead cells. Phloem carries food up and down, in living sieve tubes with companion cells.
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, compare your working with the solution.
| Xylem | Phloem | |
|---|---|---|
| Carries | water and minerals | food |
| Direction | up only | up and down |
| Main cells | vessels and tracheids | sieve tubes and companion cells |
| Alive? | mostly dead | mostly alive |
