Science Lesson 3.2
| Term | Definition |
|---|---|
| Nonvascular Plant | Plants that lack vascular tissue for transporting materials are known as nonvascular plants. |
| Rhizoid | Rhizoids are thin, rootlike structures that anchor mosses and absorb water and nutrients. |
| Vascular Plant | Vascular plants are plants with true vascular tissue. |
| Phloem | Phloem is the vascular tissue through which food moves. |
| Xylem | Xylem is the vascular tissue through which water and nutrients move. |
| Pollen | Seed plants produce pollen, which are tiny structures that contain the cells that will later become sperm cells. |
| Seed | A seed is a structure that contains a young plant inside a protective covering. |
| Gymnosperm | A gymnosperm is a seed plant that produces naked seeds. The seeds of gymnosperms are referred to as "naked" because they are not enclosed by a protective fruit. |
| Angiosperm | Angiosperms are seed plants that produce flowers and, in contrast to gymnosperms, they produce seeds that are enclosed in fruits. |
| How are Plants Classified? | Plants are classified into nonvascular, vascular, vascular seedless, gymnosperms, and angiosperms. |
| What is the Difference between Phloem and Xylem? | Food moves through the phloem, but water and nutrients move through the xylem. |
