Ch 9 Flashcards
Fragmentation
a large spreading or vining plant grows to several meters in length and individual parts become self-sufficient by establishing adventitious roots; if middle portions of the plant die, the ends become separated and act as individuals
Vegetative Reproduction
.
Ramets
.
Genets
.
Apomixis
.
Sperm and eggs
sex cells called gametes
Zygote
one sperm and one egg come together and the diploid cell which is the fertilized cell
Embryo
.
Adult sporophyte
a diploid plant that produces spores
Spores
a single cell that is a means of asexual reproduction; it can grow into a new organism but cannot fuse like a gamete
Gametophyte
a haploid plant that produces gametes
Complete Flowers
a flower having sepals, petals, stamens and carpels
Incomplete flower
a flower that is missing one or more of the four basic appendages (sepals, petals, stamens, carpels or any combination)
Pedicel
the stalk of an individual flower
Receptacle
the stem (axis) of a flower, to which all the other are attached
Sepals
in flowers, the outermost of the fundamental appendages, most often providing protection of the flower during its development
Calyx
collective term for all the sepals of one flower
Petals
the appendages, usually colored on a flower, most often involved in attracting pollinators
Corolla
a collective term for all the petals of a single flower
Stamens
the organs of a flower involved in producing microspores (pollen)
Filament
the stalk of a stamen, it elevates the anther
Anther
the portion of a stamen that contains sporogenous tissue which produces microspores (pollen)
Carpel
organ of a flower that contains ovules and is involved in the production of megaspores, seeds and fruits
Ovary
in a flower, the base of the carpel; the region that contains ovules and will develop into a fruit
