What tissue should Lisa monitor if she is developing new varieties of vegetables and wishes to test the efficiency water uptake by some vegetable varieties?

The xylem is a tissue responsible for the transport of water and minerals from the roots to the leaves. By monitoring the xylem, Lisa can assess the efficiency of water uptake by different vegetable varieties. Efficient water uptake is essential for plant growth and productivity, especially in drought-prone areas or during periods of water scarcity.
