The Structure of Plants 3 main parts: 1.Roots- take in water and nutrients from the soil. 2.Stems- move water and nutrients from the roots to the leaves. 3.Leaves- capture the energy of sunlight and use it to make food for the plant All plants are producers – they make their own food. Flower: Makes seeds for the plant. Stem: supports the plant. It contains thin tubes for carrying food, minerals, and water. Leaves: make food for the plant. They take in carbon dioxide and release oxygen into the air. Roots: soak up water and minerals. They also store food for the plant. Tubes or No Tubes One way scientist classify plants is by if they have tubes or not. Vascular: means “having tubes”. o Xylem – Tubes that carry water and nutrients from the roots to the leaves. o Phloem – Tubes that carry food from the leaves to the rest of the plant. o Examples: trees, grasses, and most garden plants. Video: Colored Flowers o Example: mosses and liverworts grow low to the ground in moist places like under rocks or the trunks of trees. o They have tiny threads that hold the plants in place but these “roots” do not take up water. Seeds or spores Another way to classify plants is by how they reproduce, or make new living things of the same kind. Seeds Most plants you see reproduce from seeds. A seed is a plant part that contains a tiny new plant, or embryo. The seed protects the new plant and contains food to help it grow. Most vascular plants make seeds. Video: Plants with Seeds Scientist divide seed plants into two more large groups: plants with flowers and plants with cones. Most plants form seeds in parts of flowers, but some plants such as pine trees, make seeds in cones. Coniferous: Plants that form seeds in cones. They are also evergreens. They do not lose their leaves in the winter. oEx. A pine tree: it’s needle shaped leaves stay on the tree all year long. Deciduous: tree that loses its leaves before winter.

• Flowering plants have different kind of flowers and seeds. • Flowers have different sizes, shapes, and colors. Poppy seeds are small, round, and black. Avocado seed is big, egg-shaped, and brown Scientist use these differences and others to classify plants www.educationdiscovery.com #1 Sunflower: Vascular or Non-Vascular?

5. Seed: a plant part that contains a tiny new plant, or embryo. 6. Spore: a plant cell that can grow into a new plant. 7. Coniferous: having cones in which seeds form. 8. Deciduous: having leaves that fall off each year. Notebook Foldable Cut out foldable to paste in your notebooks.
