cuticle
A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants.
vascular tissue
Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body.
gymnosperm
plants of the class Gymnospermae having seeds not enclosed in an ovary
stomata
the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
xylem
the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels
seed
a plant embryo that is encolosed in a protective coat
spore
a small usually single-celled reproductive body produced by many plants and some protozoans and that develops into a new individual
endosperm
nutritive tissue surrounding the embryo within seeds of flowering plants
phloem
the vascular tissue through which food moves in some plants ( food moves in any direction)
sporophyte
the spore-producing individual or phase in the life cycle of a plant having alternation of generations
gametophyte
the stage in the life cycle of a plant in which the plant produces gametes, or sex cells
angiosperm
A flowering plant, which forms seeds inside a protective chamber called an ovary.
germinate
produce buds, branches, or germinate
collenchyma
thick cell walls in irregular shapes, support the plant where it is still growing, grouped in strands.
parenchyma
loosely packed, cube-shaped, elogated with a large central vacuole and thin flexible walls. store water, nutrients, and healing.
dermal
the outermost tissue layer on a plant's roots, leaves, and stems
vascular
containing plant tissue through which water moves up and food moves down
epidermis
The outer layer of the skin of a plant
3 plant adaptations
the cuticle to keep the water in, vascular tissue to move water, and seeds and pollen for reproduction.
monocots
A clade consisting of flowering plants that have one embyonic seed leaf, or cotyledon.
dicots
angiosperm whose seeds have two cotyledons
alternation of generations
the fluctuation between haploid and diploid stages that occur in plants
3 basic types of plant cells
collenchyma, parenchyma, and schlerenchyma
3 different types of plant tissue
dermal, ground, and vascular
