Stamens
________ are reproductive structures that produce male gametophytes- also known as pollen grains.
Sexual reproduction
________ is based on meiosis and fertilization.
Germination
________ is a resumption of growth and development.
Pollination
________ (transfer of pollen grains from an anther to a stigma) occurs, and gametophytes produce sperm (male gametes) and eggs (female gametes) by mitosis.
Asexual reproduction
________ does not involve fertilization.
Meiosis
________ occurs in sporophytes and results in the production of haploid spores.
radicle
The ________, or embryonic root, emerges first, and it then develops into the mature root system.
Embryogenesis
________ is the developmental process by which a single- celled zygote becomes a multicellular embryo.
Dormancy
________ is usually a feature of seeds from species that inhabit seasonal environments, where for extended periods conditions may be too cold or dry for seedlings to thrive.
Fertilization
________ occurs when two gametes fuse to form a diploid zygote.
Self fertilization
________, or selfing, occurs when a sperm and an egg from the same individual combine to produce offspring.
Vegetative development
________ produces the nonreproductive portions of the plant body- the roots, leaves, and stems.
diploid phase
An individual in the ________ of the life cycle is called a sporophyte, while an individual in the haploid phase of the life cycle is called a gametophyte.
Sepals
________ are leaflike structures that make up the outermost parts of a flower.
Pollination syndromes
________ are suites of flower characters that are associated with certain types of pollinators.
Meiosis
________ and spore production occurs inside structures called sporangia.
