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 |
