Classifying Plants
Ch 3 L2
| Term | Definition |
|---|---|
| Non- vascular plants | Plants that have no true vascular tissue |
| Rhizoid | Thin root like structure that anchor to the ground and transport water. |
| Vascular plant | Plants with specialized vascular tissue that includes xylem and phloem |
| Phloem | The vascular tissue through which food moves in some plants. |
| Xylem | The vascular tissue through which water and minerals move in some plants. |
| Front | The leaf of a fern plant |
| Pollen | Tiny structure (male gametophyte) produced by seed plants that contain the cell that later becomes a sperm cell. |
| Seed | The plant structure that contains a young plant and a food supply inside a protective covering. |
| Gymnosperm | A plant that produces seeds directly on the scales of cones—not enclosed by a protective fruit. |
| Angiosperm | A flowering plant that produces seeds enclosed in a protective fruit. |
| Cotyledon | A leaf produced by an embryo of a seed plant; sometimes stores food. |
| Monocot | An angiosperm that has only one seed leaf. |
| Dicot | An angiosperm that has two seed leaves. |
| What are the two types of vascular tissue and what do they do? | The two types of vascular tissue are xylem and phloem. Xylem is responsible for trans[porting water, and phloem is responsible for transporting sugars. |
| What are the three groups of seedless, vascular plants? | 1. Lycophytes 2. Pterophytes 3. Psilophytes |
| What are the 2 characteristics of seed plants? | The presence of vascular tissue and the production of seeds for reproduction |
| What are the four main groups of plants? | 1. Bryophytes 2. Pteridophytes 3. Gymnosperms 4. Angiosperms |
| What are the 3 characteristics of non vascular plants? | 1. Lack of vascular system 2. Reliance on moist environments 3. Dominance by the gametrophyte generation in their life cycle |
| Where do non-vascular plants typically live and what is their size? | They live in damp shady environments, their size is few inches tall rarely exiting 10 centimeters (4 inches) in height |
| How do non-vascular plants get nutrients.? | They get nutrients from the soil. |
| What are the three groups of non-vascular plants? | 1. Mosses 2. Liverworts 3. Hornworts |
| What are the 2 functions of vascular tissues? | Transport and support |
| What are the 2 characteristics of seedless, vascular plants? | The presence of the vascular tissue and the reproduction through spores. |
| What are the 2 characteristics of seed plants? | Gymnosperm and Angiosperm |
| How do seed plants reproduce? | Pollination, Fertilization, Dispersal |
| What are the two groups of seed plants? | Angiosperms and gymnosperms |
| What are two examples of gymnosperm? | Gnetophytes Cycads |
| What are the two ways that Angiosperms are different from Gymnosperms? | Angiosperms have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have unenclosed or “naked” seeds on the surface of scales or leaves. Angiosperms have flowers and fruits, while gymnosperms do not. |
| What are the two major groups of angiosperms? Give an example of each. | Dicots Monocots |
