Corn has a xylem tissue and a phloem tissue for transport of water and starch, Corn is a

Miss.Omeshi wanted year 11 students to observe xylem and phloem in a plant. She brought a plant to the lab and observed a stem section under the microscope. Surprisingly they were not able to observe any vascular tissues.

• The plant is not a vascular plant

• The plant is dead

• Microscope is faulty

Water is absorbed through the root hairs and transported to the leaves through

• Phloem

• Parenchyma

• Xylem

• Mesophyll
