cuticle
the waxy, waterproof layer that covers the leaves and stems of most plants
vascular tissue
System of tubelike structures inside a plant through which water, minerals, and food move
zygote
a fertilized egg
nonvascular plants
Plants that lack a well-developed system of tubes for transporting water and other materials
vascular plant
Plant with tube-like structures that move minerals, water, and other substances throughout the plant.
sporophyte
the stage in the life cycle of a plant in which the plant produces spores
gametophyte
the stage in the life cycle of a plant in which the plant produces gametes, or sex cells
rhizoid
thin, root-like structures which anchor moss and absorb water and nutrients from the soil
frond
compound leaf of a fern or palm or cycad
phloem
the vascular tissue through which food moves
xylem
Nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves
pollen
tiny structures that contain the cells that will later become sperm cells
seed
The plant structure that contains a young plant inside a protective covering
embryo
the young plant that develops from the zygote
cotyledon
first leaf or first pair of leaves produced by the embryo of a seed plant
germination
occurs when the embryo begins to grow again and pushes out of the seed
root cap
protects the root from injury from rocks as the root grows through the soil
cambium
The layer of cells in a plant that produces new phloem and xylem cells
transpiration
The process by which water is lost through a plant's leaves
gymnosperms
vascular plants with no flowers or fruit; produce seeds in cones
cone
The reproductive structure of a gymnosperm
ovule
structure in seed cones in which the female gametophytes develop
pollination
transfer of pollen from the male reproductive structure to the female reproductive structure
angiosperm
flowering plant
flower
the reproductive structure of an angiosperm
sepal
a leaflike structure that encloses the bud of a flower
petal
A modified leaf of a flowering plant. Petals are the often colorful parts of a flower that advertise it to insects and other pollinators.
stamen
the male reproductive organ of a flower
pistil
The female reproductive part of a flower
ovary
protects the seeds as they develop
fruit
a ripened ovary and other structures that enclose one or more seeds
monocot
an angiosperm that has only one seed leaf, petals in multiples of three, and leaves with parallel veins
dicot
angiosperm with two cotyledons inside its seed, flower parts in multiples of four or five, leaves with branching veins and vascular bundles in rings
