Plant Diversity

	the alternation of a sexual phase and an asexual phase. The sexual phase is called the gametophyte and produces gametes. The asexual phase is called the sporophyte and produces spores asexually.
	the male sex organ of spore-producing plants
	Reproductive structure that produces eggs in seedless plants
	a dry dehiscent seed vessel or the spore-containing structure of e.g. mosses
	the gamete-producing individual or phase in the life cycle of a plant having alternation of generations
	upper part of moss capsule often specialized for spore discharge
	A mass of green, branched, one-cell-thick filaments produced by germinating moss spores.
	any of various slender filaments that function as roots in mosses and ferns and fungi etc
	stalk of a moss capsule
	organ containing or producing spores
	the spore-producing individual or phase in the life cycle of a plant having alternation of generations
	a plant body without true stems or roots or leaves or vascular system
	row or cluster of thick walled cells on a sporangium that function in spore release
	Referring to a plant species that has a single kind of spore, which typically develops into a bisexual gametophyte.
	Referring to a plant species that has two kinds of spores: microspores, which develop into male gametophytes, and megaspores, which develop into female gametophytes.
	a membrane enclosing and protecting the developing spores especially that covering the sori of a fern
	a plant structure that produces megaspores
	a plant structure that produces microspores
	In lycophytes, a small leaf with a single unbranched vein.
	Fern spore germinates into a heart-shaped structure
	Leafless axes that branch at their tips. Found in Selaginellas.
	cluster of sporangia usually on underside of a fern frond
	Compact cluster of spore-bearing structures found in seedless vascular plants
	in non-flowering plants, a sporophyll that bears only microsporangia
	A spore from a heterosporous plant species that develops into a male gametophyte.
	Structure that grows from a pollen grain to an ovule, enabling a sperm to pass directly to an egg
	Layer of sporophyte tissue that contributes to the structure of an ovule of a seed plant.
	the part of the stamen that contains pollen
	A spore from a heterosporous plant species that develops into a female gametophyte.
	in plants, a flower structure that contains one or more ovules from which female gametophytes are produced; in animals, the female gonad that produces eggs
	The female reproductive organ of a flower, consisting of the stigma, style, and ovary.
	a single cell, which grows in the sporangium. grows and undergoes meiosis to produce four haploid megaspores
	a small or immature ovum
	the male gametophyte of a heterosporous plant; pollen grain in a seed plant.
	that part of the ovary of a flowering plant where the ovules form
	Just below the epidermis and has special U-shaped wall thickenings; the special wall thickening function in anther opening for pollen release.
	tiny particles (male gametophytes) produced by seed plants that contain the cells that later become sperm cells
	The chamber or opening inside the ovary where the ovules are found
	a spore from a heterosporous plant species that develops into a male gametophyte
	a mature fertilized plant ovule consisting of an embryo and its food source and having a protective coat or testa
	the female gametophyte produced by the megaspore of a plant that produces both microspore and megaspores
	the pollen-producing reproductive organ of a flower, consisting of an anther and a filament.
	inner part of an ovule, in which the embryo sac develops; equivalent to a megasporangium
	layer of cells lining the chamber of anthers (microsporangia) which supplies nutrients to developing pollen grains
	a dense clusters of flowers or foliage
	the cuplike or ringlike or tubular structure of a flower which bears the sepals and stamens and calyx
	group of bracts more or less held together as a unit, subtending a flower, fruit, or inflorescence
	enlarged tip of a stem that bears the floral parts
	Green Algae
