57 Cards in this Set

  • Front
  • Back
the production of offspring that does not involve the union of gamets
asexual reproduction
an asexual division of prokaryotes that produces identical offspring
binary fission
eukaryotic nuclear division
mitosis
a form of asexual reproduction in which the part of a cell pinches off an offspring cell.
Budding
a resistant reproductive cell of some organisms; such as some plants, fungi, and protists
Spores
a form of asexual reproduction in which individual cells are released that act as spores
fragmentation
asexual reproduction in plants
vegetative propagation
the production of offspring from the combination of genetic material from two parent organisms;.
sexual reproduction
in plants and algae, a multicellular structure that produces gamets; dominant species in nonvascular (moss)
gametophyte
one of the diploid generation of land plants that produces spores; dominant generation in vascular (oak) plants
sporophyte
the diploid cell that results from the fusin of gametes
zygote
a seed plant whose seeds are not enclosed by an ovary or fruit
gymnosperm
a seed plant whose seeds are protected in an fruit (ripened ovary); a.k.a flowering plant
Angiosperm
an angiosperm with a single cotyledon, parallel veins, and flower parts in multiples of 3's
Monocotyledones
an angiosperm with two cotyledons. netted intertwining veins, and flower parts in multiples of 4's and 5's
Dicotyledones
the swollen tip of the branch/stem which is the base of the flower
receptacle
a modified leaf that protects the younger flower, usually smaller then the pedals
Sepal
one of the leaf-shaped parts of the corolla of a flower, usually brightyl colored and conspicuous
Petal
the structure in the flower that produces pollen
Stamen
the microsporangium of an angiosperm in which pollen grains are produced
anther
the structure that supports the anther
filament
a plant structure formed of fused carpels
pistil
an expanded apex of a pistil, supported by the style; the part of the pisitl that recieves the pollen
stigma
the stalk-like structure of the ovary
style
the egg producing organ in a plant
ovary
A small opening in the ovule of a seed plant through which the pollen tube usually enters
Micropyle
the larger of the two kinds of spores; produced by meiosis in a megasporangium
Megaspore
The smaller of the two kinds of spores; produced by meiosos in a megasporangium
Microspore
the microgametophyte of seed plants
pollen grain
the transfer of pollen from the anther to the stigma of a flower of the same species
Pollination
the process in which two types of cell fusion take place in the embryo sac
Double Fertilization
one of the small vesicles containing a developing ovum in the ovary of a mammal
graafian follicle
The divisions of the zygote immediately following fertilization
cleavage
a ball of cells produced by cleavage of the zygote
morula
a hollow ball of cells formed when a zygote goes through repated cycles of cell division
blastula(blastocyst)
The blastula collapsing, which forms a cup-shaped gastrula (embryo) with a gut called the archeteron, and multiple layers
gastrulation
the outside germ layer of the gastrula; forms skin, hair, nails and nervous system
ectoderm
the insider germ layer of the gastrula; surrounds the archeteron
endoderm
In most phyla, the third layer formed between the endoderm and ectoderm; forms skeleton, muscles, inner layer of skin, circulatory system, and lining of the body cavity
mesoderm
an organism in which the blastopore develops into the mouth and the coelom arises by schizocoely whos embryo has gone through spiral cleavage; "first mouth"
protostome
each cell in the blastula nestles between 2 cells of the adjacent row
spiral cleavage
the blastopore develops into the anus and a second opening becomes the mouth through radial cleavage; "second mouth"
deuterostomes
the cell divisions are parallel to or at right angles to the axis from one pole of the blastula to the other
radial cleavage
a process in which each cell develops into a specific part of the gastrula
determinate cleavage
a pattern of development in which the functional destiny of each cell is not determined early in the development of the embryo
indeterminate cleavage
the coelom formation in protostomes that involces splitting the embryonic mesoderm into two layers
schizocoely
the process of mesoderm formation in deuterostomes in which the coelom forms in folded mesoderm
enterocoely
type of body cavity-"no body cavity"....in flatworms and he interior of the animal is solid mesoderm
acoelomate
type of body cavity-"false body cavity"...in rotifers and roundworms, and the mesoderm lines the fluid-filled coelom and the gut is suspended in the fluid of the coelom
Pseudocoelomate
type of body cavity-"true coelom"...mesoderm lines the body cavity and surrounds and supports the gut, forms liver and lungs;;mollusks, annelids, arthropods, chordates, echinoderms
Coelomate
laying/releasing of eggs (maternal connection)
Oviparous
born live from eggs (no maternal connection);;always internal
oviviparous
born live with a maternal connection;;;always internal
viviparous
done by some fish, involves depositing of eggs in nest and sperm being released over the eggs
Spawning
Thin membrane enclosing fluid in which the embryo forms
Amnion
surrounds all the other membranes and helps protect the embryo (part of placenta in mammal)
Chorion
stores nitrogenous wastes produced by the embryo and acts as a "lung"
Allantois
