| What 6 characteristics describe the organism - plant? | 1. eukraryates 2. multicellular 3. tissues 4.chloroplasts 5. cell walls 6. cellulose |
| What are two ways the plant kingdom are broken into smaller groups? | 1. nonvascular 2.vascular |
| What is the shape or form of an organism? | morphology |
| What is a region where a leaf is or was attached? | nodes |
| what are taproots? give two examples? | HAS ONE OR FEW MAIN ROOTS , CARROTS, DANDELLIONS |
| A Chloroplast is a plastid. What pigment does it contain? | Chlorophyll |
| What is composed of long chains of sugar and makes plant cell walls rigid and strong? | cellose |
| What are 3 patterns of venation in leaves ? | Parellel, Palmote, Pinnate |
| The part of the leaf in between the node and the blade. The veins in the leaf will meet up and flow throught the petiole into this | Stem |
| What are the 3 types of arrangements of the leaves on the stems? | Alternate, opposite and whoried |
| What are 2 important cellular structures of all plant cells ? | cell walls and plastids |
| What 2 things give plant c ells their strength? | Turgo pressure and cell walls |
| Strawlike, Long hollow cells that carry water up from the roots to the stems and leaves. | Xylem |
| The tissue in plants that carries sugar from the leaves to the rest of the plant. A different sugar solution than what is in the Xylem | Phloem |
| Long narrow cells that taper to points at end. Very strong. Main job is to support the vascular bundles. Used to make thinks like rope and cloth | Fibers |
| Outermost tissue of plants in young leaves, stems and roots. Also secretes the cuticle. | Epirdemis |
| Waxy stubstance made by the epidermis. A protective covering that helps reduce water loss | cuticle |
| What are the 3 major divisions of plant groups | nonvascular, seedless vascular, seeded vascular |
| What are non vascular plants and give 3 examples | parts that look like roots, layers or singles cells and no vascular tissue. ecamples are mosses, liverworts, hornwarts(hlm) |
| Describe seedless vascular plants and list 3 examples | don't have seeds and have vascular tissues. ex: ferns, clubmoss, horsetails (cfh) |
| what are the 2 main parts of a fern | fronds, rhizome |
| what is the difference between spores and seeds | spores aren't covered, sees are covered spores aren't covered, seeds are covered |
| What are seed bearing vascular plants and list examples | Most familir plant. Seeds are produced by flowers. Have seed and vascular tissuePeach, apple, watermelon, dandelions, roses. |
| What is known as naked seed or not fully covered? An ex: are conifers and help make paper | gymnosperm |
| What is known as covered seed and are completely covered by protective covering called a fruit. Fruits develop from flowers. | giosperms |
| Flowering plants are called? | seed plants |
| An example of a fibrous roots | grass |
| What is a blade | Flat green part of leaf |
| What are smaller leaves called | leaflets |
| Blades are composed of several smaller leaves | Compound |
| Water and sugar conducting tissues are called | Veins |
| What are 2 types of stems | Woody and herbaceous |
| What are 4 main organs in a plant | Root, stem, leaves and flowers (FLRS) |
| How are the 4 main organs related to the nodes | Roots do not have nodes. stems have nodes. leaves do not have nodes but are attached at stems at nodes |
