|
bark
|
All tissues external to vascular cambium.
|
|
|
bud
|
Undeveloped shoot, mainly meristematic tissue. Small, protective scales often cover it.
|
|
|
collenchyma
|
A simple plant tissue that imparts flexible support during primary growth, as in lengthening stems.
|
|
|
cork
|
Periderm component; insulates, protects, and waterproofs woody stems and roots.
|
|
|
cork cambium
|
Lateral meristem that replaces epidermis with cork on woody plant parts.
|
|
|
cortex
|
A rindlike layer. In vascular plants, a ground tissue; supports parts and stores food.
|
|
|
cuticle
|
Body cover. Of plants, a transparent covering of waxes and cutin on outer epidermal cell walls. Of annelids, a thin, flexible coat. Of arthropods, a lightweight exoskeleton hardened with protein and chitin.
|
|
|
dermal tissue system
|
Tissues that cover and protect all exposed surfaces of a plant.
|
|
|
dicot
|
[Gk. di, two, + kotyledon, cup-shaped vessel] Dicotyledon. Flowering plant generally characterized by embryos with two cotyledons; net-veined leaves; and floral parts arranged in fours, fives, or multiples of these.
|
|
|
epidermis
|
Outermost tissue layer of plants and all animals above sponge level of organization.
|
|
|
fibrous root system
|
All lateral branchings of adventitious roots arising from a young stem.
|
|
|
ground tissue system
|
Tissues, parenchyma especially, making up most of the plant body.
|
|
|
growth ring
|
One of the alternating bands of early and late wood; a tree ring.
|
|
|
hardwood
|
Type of strong, dense wood with many vessels, tracheids, and fibers in xylem.
|
|
|
heartwood
|
A dry tissue at the core of aging stems and roots that no longer transports water and solutes. It helps the tree defy gravity and is a dumping ground for some metabolic wastes.
|
|
|
lateral root
|
Outward branching from the first (primary) root of a taproot system.
|
|
|
leaf
|
Chlorophyll-rich plant part adapted for sunlight interception and photosynthesis.
|
|
|
meristem
|
A localized region of a plant where undifferentiated cells give rise to cell lineages that form all of the mature tissues.
