stomata
a tiny pore in the outer layer epidermis of a plant leaf or stem that controls the passing of water vapor and other gases into and out of the plant
charophyte
any green algae of the class Charophyceae (or group Charophyta), comprising the stoneworts.
homosporous
having the spores of one kind only
heterosporours
having more than one kind of spore
mega spores
one of four haploid spores, usually larger than the microspore, formed in the megasporangium from a megaspore mother cell, and from which the megagametophyte, or female gametophyte, develops.
epiphytes
A plant, such as a tropical orchid or a staghorn fern, that grows on another plant upon which it depends for mechanical support but not for nutrients. Also called aerophyte, air plant.
ovule
the plant part that contains the embryo sac and hence the female germ cell, which after fertilization develops into a seed.
fiber
fine, threadlike piece, as of cotton, jute, or asbestos.
2. a slender filament: a fiber of platinum.
3. filaments collectively.
stamen
the pollen-bearing organ of a flower, consisting of the filament and the anther.
carpal
relating to the bones in the wrist
embyosac
the megaspore of a seed-bearing plant, situated within the ovule, giving rise to the endosperm and forming the egg cell or nucleus from which the embryo plant develops after fertilization
cross-pollination
the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
hyphae
(in a fungus) one of the threadlike elements of the mycelium.
mycelium
the mass of hyphae that form the vegetative part of a fungus.
septa
a dividing wall, membrane, or the like, in a plant or animal structure; dissepiment
coenocytic
an organism made up of a multinucleate, continuous mass of protoplasm enclosed by one cell wall, as in some algae and fungi.
plasmogamy
the fusion of the protoplasts of cells
karyogamy
the fusion of the nuclei of cells, as in fertilization
chytrids
any of the simple, algaelike fungi constituting the class Chytridiomycetes, order Chytridiales, of aquatic and soil environments, having flagellated zoospores and little or no mycelium
sac fungi
a fungus that produces spores sexually inside a membranous spore case ascus, e.g. a yeast or truffle. Class Ascomycetes.
asci
the sac in ascomycetes in which the sexual spores are formed.
ascocarp
(in ascomycetous fungi) the fruiting body bearing the asci, as an apothecium or perithecium.
conidia
(in fungi) an asexual spore formed by abstriction at the top of a hyphal branch
basidium
a special form of sporophore, characteristic of basidiomycetous fungi, on which the sexual spores are borne, usually at the tips of slender projections.
mold
a growth of minute fungi forming on vegetable or animal matter, commonly as a downy or furry coating, and associated with decay or dampness.
lichen
any complex organism of the group Lichenes, composed of a fungus in symbiotic union with an alga and having a greenish, gray, yellow, brown, or blackish thallus that grows in leaflike, crustlike, or branching forms on rocks, trees, etc.
soredia
a group of algal cells surrounded by hyphal tissue, occurring on the surface of the thallus and functioning in vegetative reproduction.
protoplasts
the contents of a cell within the cell membrane, considered as a fundamental entity.
b. the primordial living unit or cell.
