Understanding Plant Classification: Vascular vs. Nonvascular

In 5th grade science, students learn how scientists classify plants into two major groups: vascular and nonvascular. Vascular plants, such as corn, have specialized tubes that transport water and nutrients throughout the plant. In contrast, nonvascular plants, like moss, lack these tubes and have tightly packed cells that draw water directly from their surroundings. This lesson explores the distinguishing features of each group and examines the microscopic structures that differentiate moss from corn, highlighting the unique adaptations of each type.

Presentation Transcript

  1. How do we classify Plants? 5th Grade

  2. Scientists study what is INSIDE plants to divide them into 2 groups. What are these 2 groups called? • 1) Vascular plants • 2) Nonvascular plants

  3. Moss

  4. Corn

  5. What is the difference between the microscopic view of the moss and the microscopic view of the corn?

  6. 2 types of plants • Moss = tightly packed cells that look like a jigsaw puzzle  NONVASCULAR • Corn = tube-like cells that tunnel up and down the stem  VASCULAR

  7. Vascular = “composed of or containing vessels” • Water is taken in by a plant’s roots and moves up a set of tubes toward the plant’s leaves, flowers, and other parts • Foods made in the leaves move down the other set of tubes, leading to the plant’s parts • VASCULAR TISSUE

  8. Vascular Plants have tubes that… • Transport water and nutrients over a distance

  9. Vascular Plants: have roots, stems, leaves

  10. Nonvascular Plants • Plants that do not have vascular tissues (tubes to connect different parts of the plant and transport materials)

  11. In Nonvascular Plants, water from the outside passes directly into the cells…
