science test
a node by a stalk where most leaf blades attach to
Petiole
a creeping stem that grows along the ground
stolon
plant with a long, thin stem that grows along the ground or has tendrils that twine around a wall or other support; can be either woody or herbaceous
vine
tiny, one-celled reproductive structures that will eventually produce new plants
spores
structure made of layers of thick, fleshy leaves surrounding a very short stem; store food during the growing season, allowing the plants to live after their flowers and above-ground leaves and stems have died
bulb
plants that can survive in every climate in the world
moss
the inner portion of a root that consists of storage cells surrounding the root’s transportation system
cortex
monocot family whose members grow from bulbs, corms, or rhizomes and have inferior ovaries. Eg. Chive, Amaryllis, or daffodil
amaryllis
the primary root remains small and many slender secondary roots grow from it in all directions; commonly with monocots
fibrous root systems
plants without vascular systems, include mosses and liverworts
Bryophytes
tissue that carries water and nutrients from the root hairs to the leaves, where the water is used in photosynthesis or released through the stomata
xylem
consists of three or more leaves growing from the same node on the stem
whorl
margins of leaves that are smooth and unbroken
entire
arrangement of flowers that have stems of nearly equal length emerging from a common point on the main stem
umbels
similar to a spike except that the flowers grow on small stems that branch off the main stem
racemes
plants having no petioles but instead attach directly to the stem by a sheath
sessile
most unique seedless plants
fern
spore-forming plants that bears spores in club-shaped, cone-like structures
club moss
plants that have the same general structure as mosses
liverworts
when the leaflets of a compound leaf attach at a common point on the petiole’s tip
palmately compound
allow the root to grow in diameter
cambium cells
plants with chlorophyll-containing stems that carry on photosynthesis instead of its tiny green leaves
Horsetail
long flower arrangements with clusters attached directly to the stem
spikes
plants with vascular systems
Tracheophytes
plants that reproduce by seeds but their seeds are not enclosed in an ovary
Gymnosperms
