Sadie and Jason were hard at work in their school’s garden. Along with other members of the school’s gardening club, they were planting white carnations in the shape of a wolf, the school’s mascot. It was part of the school’s St. Patrick’s Day celebration the next day.
“Time to water the flowers!” said Mr. Clark, the club’s adviser. He handed watering cans to the students. Jason began dumping water on the top of each flower. Some of the flower petals fell off under the water’s weight.
“Be careful!” said Sadie.
“I don’t want them to wilt before tomorrow,” Jason said.
“But you don’t need to pour the water on top of the plants,” said Sadie. “Flowers like carnations have tubes inside them that carry water from their roots to other parts of the plant. You should put the water in the soil, and the plants will suck it up from there.”
“That’s right,” said Mr. Clark. “Plants with those structures are called vascular plants.”
Jason nodded and poured the rest of his water on the soil.
