4. Unit 4 Lesson 3 How Do Plants Grow and Reproduce?
Tubes for Transport
Nonvascular plants are simple plants that lack vascular tissue, which easily transports water from the ground into the plant.
They grow in damp places and almost never grow taller than 10 cm.
Nonvascular plants move materials by absorbing nutrients and water in the same way that a sponge absorbs water.

Vascular plants have vascular tissues that allow them to move water, nutrients, and sugars across long distances.
Vascular plants have true leaves and roots.
Most plants, including trees, grasses, and shrubs, are vascular plants.

Tubes for Transport
Vascular tissue contains tiny tubes, which move water and nutrients up a plant in the same way that water moves up a straw.
Vascular tissue includes two kinds of smaller tubes. Xylem carries water and nutrients from the roots to the other parts of the plant.
Phloem carries sugar from the leaves to the rest of the plant.
