angiosperm
a flower-producing vascular plant in which the seed is enclosed in a fruit, such as an apple.
auxin
a plant hormone that causes plant stems and leaves to grow or bend toward light.
Cambium
vascular plant tissue that produces new xylem and phloem cells.
Cone
The conical fruit of the pine (aka pinecone)
Cotyledon
The primary leaf of the embryo of seed plants.
Cuticle
A waxy protective layer on the stems and leaves of land plants that helps the plant converse water.
Dicot
An angiosperm having two seed leaves inside its seed. Ex) Maple tree
Embryo
fertilized egg during early growth, in humans, an unborn child during the 1st two months of pregnancy.
Flower
The part of the seed plant comparing the reproduce organs.
Frond
The leaf of a fern.
Fruit
The edible part of a plant developed from a flower.
Gametophyte
The sex-cell producing stage of a plant's life cycle.
Gymnosperm
Vascular plant that produces seeds on the scales of female cones such as pine cones.
Germination
To develop into a plant as a seed/spore/bulb.
Hydroponics
Cultivation of plants by placing the roots into liquid nutrients rather than soil.
Monocot
Angiosperm having a single seed leaf inside its seed. Ex) An orchid
Nonvascular
Plant lacking vascular tissue; it absorbs water directly through its cell membrane.
Ovary
In angiosperm, the swollen base of the pistil, where ovules form, in female animals the organ produces ova, or egg cells.
Ovule
Female reproductive part of a plant that produces the egg.
Petal
One of the colored segments of a corolla of a plant.
Phloem
Vascular plant tissue made up of tubular cells that move food from leaves and stems to other parts of the plant for use or storage.
Pistil
The female reproductive organ of a flower.
Pollen
The male reproductive part of a plant that contains the sperm.
Pollination
Process that transfers pollen grains from the stamen to the stigmas.
Rhizoid
Rootlike filament containing only a few long cells; it holds moss plants in place.
Root Cap
A thimble shape mass of cells that cover and protects the root tip of plants.
Seed
The fertilized mature ovula of a flowers plant.
Sepal
One of the individual leaves or parts of the calvx of a flower.
Sporophyte
The spore forming stage of a plants life cycle.
Stamen
The male reproductive organ of a flower.
Stomata
Small pores in the surface of a plant leaf that allows carbon dioxide water and oxygen to enter and leave.
Transpiration
Loss of water vapor through the stomata of a leaf in plants.
Tropism
The response of a plant to a stimulus.
Vascular Tissue
The supportive and conductive tissue in plants, consisting of xylem and phloem.
Xylem
Vascular plant tissue made up of tubular vessels that transport water and minerals from the roots up through the plant.
