Science Explosion 07

BJU 6th Science - Chapter 6

Vascular plant plants with tubelike structures that transport water from the roots to the stem and leaves
Nonvascular plant plants without tubelike structures
Rhizoid thin, root-like structure of moss (not true root)
Rhizome underground stems
Frond leafy branch of a fern from rhizome to tip
Fiddlehead a fern frond coiled up tightly when growth first begins
Angiosperm vascular plants that have flowers and their seeds are protected inside a fruit
Gymnosperm vascular plants with no flowers, seeds are usually produced inside a cone
Annual angiosperm with only one growing season
Biennial angiosperm needing two growing season to fully develop
Perennial angiosperms that live for three or more years
Cotyledon tiny seed leaves of the plant embryo
Dicotyledon two cotyledons in their seeds
Monocotyledon only one cotyledon in their seeds
Taxonomy branch of science that deals with classifying organisms
Xylem tubes that carry water and minerals from the roots to the top of the plant
Phloem tubes that carry sugars and food throughout the plant
Vascular bundle xylem and phloem tubes grouped together
Cambium a layer of cells in the vascular bundle that reproduce to make more xylem and phloem
Tuber food storage stem of a plant, ex. potato
Herbaceous soft and green stems like those of a flower, generally are annual plants
Root anchors the plant in the soil, supports the stem, absorbs water and nutrients, some store starches and sugars for the plant, ex. beets, radishes and sweet potatoes
Primary root first root that emerges from the seed
Taproot continues to grow from primary straight down into the soil and may have secondary roots branching off it
Fibrous root primary root stops growing and the plant develops many thin roots that spread out in all directions with a few that branch downward for water and minerals
Arial root never touch the soil due to high humidity
