alternation of generations
meiosis
process by which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell
sporophyte
the spore-producing individual or phase in the life cycle of a plant having alternation of generations
secondary oocyte
..., A haploid cell resulting from the first meiotic division of oogenesi (not that the cytoplasmic division in this case is unequal, producing one large cell with almost all of they cytoplasm - the secondary oocyte- and one smaller cell with virtually no cytoplasm - the first polar body.). The secondary oocyte (along with some follicular cells) is released from the ovary during ovulation.
sequential hermaphroditism
..., An individual reverses its sex during its lifetime
zoospores
..., Flagellated spores
antheridia
..., Male gametangia
sperm
..., Male sex cell
internal fertilization
..., Process in which eggs are fertilized inside the female's body
karyogamy
..., The fusion of nuclei of two cells, as part of syngamy.
spore
..., a small usually single-celled reproductive body produced by many plants and some protozoans and that develops into a new individual
egg
..., animal reproductive body consisting of an ovum or embryo together with nutritive and protective envelopes
spore mother cell
..., cell from which a spore develops
primary oocyte
..., diploid cell in prophase 1 of meiosis that can be hormonally triggered to develop into an ovum
pupae
..., dolls
protogynous
..., female first wrasses
archegonia
..., female gametangia
zygote
..., fertilized egg
regeneration
..., forming again (especially with improvements or removal of defects)
plasmogamy
..., fusion of cytoplasm
larvae
..., immature insects that do not look like adult insects
fertilization
..., making fertile as by applying fertilizer or manure
sporangia
..., multicellular organs that produce spores
medusa
..., one of two forms that coelenterates take: is the free-swimming sexual stage in the life cycle of a coelenterate and has a gelatinous umbrella-shaped body and tentacles
homosporous plant
..., produce single bisexual spore type.
heterosporous plant
..., produce two types of spores, some yeild male gametophytes (microspores) and others produce female gametophytes (megaspores).
budding
..., reproduction of some unicellular organisms (such as yeasts) by growth and specialization followed by the separation by constriction of a part of the parent
fission
..., reproduction of some unicellular organisms by division of the cell into two more or less equal parts
gonads
..., reproductive glands-male, testes; female, ovaries
fragmentation
..., separating something into fine particles
external fertilization
..., the process by which the female lays eggs and the male fertilizes them once they are outside of the female
oogenisis
..., the production of mature egg cell
syngamy
..., the union of gametes in fertilization
parthenogenisis
..., unfertelized birth
protandrous
..., when the male part of a flower matures first
alternation of generations
A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants.
gametophyte
the gamete-producing individual or phase in the life cycle of a plant having alternation of generations
