  1. How are plants grouped?Guided Reading

  2. What is the Big Idea of the lesson? • You will learn: • The groups into which plants can be grouped. • About two groups of plants that make seeds. • About two groups of plants that do not make seeds

  3. Grouping Plants • Plants grow in many shapes and sizes. • All plants use water, carbon dioxide, and energy from sunlight to make sugar. • Scientists group plants by the ways in which they are similar and different. • When scientists do this they classify the plants. • One way that scientists classify plants by how they reproduce. • Scientists classify plants into two large groups. • Plants in one group make seeds. • Plants in the other group do not make seeds.

  4. Plants that make seeds • Two examples of plants that make seeds are sunflowers and pine trees. • Plants that make seeds can be sorted into two different groups. • Plants in one group have flowers, and plants in the other group do not have flowers. • A plant that makes seeds and has flowers is called a flowering plant • A plant that makes seeds but does not have flowers is a conifer.

  5. Plants that do not make seeds • Ferns and mosses do not make seeds. • They reproduce by forming tiny cells that can grow into new plants. • Each tiny cell is called a spore.

  6. Lesson 1 review • What is one way to classify all plants into two groups? • How do flowering plants and conifers differ in the way they make seeds? • How do plants that do not make seeds reproduce?
