Botany
| Question | Answer |
|---|---|
| Classifying | sorting them in groups by size, shape, color, how they reproduce or produce offspring |
| Nonvascular: | have no vessels, no roots, no stems or leaves. Examples: Mosses & Liverworts |
| Vascular: | have vessels to transport food and water. They have roots, stems and leaves. Example: Grass, corn, trees, flowers, bushes |
| Xylem: | transports water |
| Phloem: | transports food & nutrients |
| Gymnosperms | A plant that produces seeds that are exposed rather than seeds enclosed in fruits |
| one | monocots have ____ cotyledon |
| parallel | Monocots have _________ veins on leaves |
| monocots | have 3 part symmetry for flowers |
| symmetry | the quality of being made up of exactly similar parts facing each other or around an axis. |
| fibrous | part of a root system in which roots branch to such an extent that no single root grows larger than the rest |
| Dicots | Flowering plant whose embryos have 2 cotyledons. |
| Angiosperms | flowering plants that produce seeds in fruit . |
| taproots | deep roots that have tiny hairs to absorb water and nutrients |
| Roots | Absorbs water and minerals from the ground. Anchors plant in ground. |
| TRANSPIRATION | Evaporation of water from the leaves of a plant |
| Stems | Carry substances between roots and leaves; provide support for plant; holds leaves up to sunlight |
| xylem | vascular tissue that carries water upward from the roots to every part of a plant |
| phloem | the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves. |
| herbaceous | non woody |
| woody | hard and rigid |
| Photosynthesis | 6CO2 + 6H2O + light |
| leaves | Photosynthetic organ of the plant, used to convert sunlight into food |
| Stomata | pores within the leaf that open to let CO2 in and O2 out. Guard cells open and close. |
| Cuticle | waxy covering on leaf that prevents water loss |
| Flower | The reproductive structure of an angiosperm |
| Stamen | The male part of the flower |
| PISTIL | The female part of the flower |
| Reproduction | The means in which a plant makes new plants, typically via flower or cones and seeds. |
| Pollen | is produced by the stamen. A fine dust that contains the sperm of seed |
| Asexual | Sometimes called vegetative reproduction. These types of plants are able to reproduce through structures such as rhizomes, tubers, corms, plant |
| Germination | occurs when a seed sprouts (usually caused by changes of temperature and moisture) |
| Perennials | live several years, and reproduce many times, woody plants are perennials |
| Annuals | a plant that completes its life cycle in one growing season (grows, flowers, reproduces and then dies) |
| Biennials | takes two growing seasons to complete, it reproduces in the second growing season |
| MERISTEMS | Plants grow only at their tips in regions called |
| PRIMARY | GROWTH makes a plant taller at roots and stems |
| SECONDARY | GROWTH makes a plant wider, or adds woody tissue |
| Rings | tree ______ tell the age of a tree, each ring represents a growing season. The photo shows a tree who has been through four growing seasons. The lighter thinner rings are winter periods. |
| VASCULAR | ________ cambium area of the tree that makes more xylem and phloem and forms the annual rings |
