3825791397	At the base of the style is an _____ containing one or more _____	ovary ovules	5
3825793227	A single carpel or group of fused carpels is called a	pistil	6
3825794923	A stamen consists of a filament topped by an _____ with pollen sacs that produce pollen	anther	7

3825868943	what kind of flowers lack one or moe floral organs (stamens or carpels)	incomplete flowers	9
3825884466	what are clusters of flowers called	inflorescences	10
3825949530	what is the female gametophyte that develops within the ovule	embryo sac	11
3825964290	consists of the two-celled male gametophyte and the spore wall	pollen grain	12
3825966561	Pollen develops from _____ within the microsporangia, or pollen sacs, of anthers	microspores	13
3826033398	In angiosperms, ______is the transfer of pollen from an anther to a stigma	pollination	14
3826082786	After landing on a receptive stigma, a pollen grain produces a _____ that grows down into the ovary and discharges two sperm cells near the embryo sac	pollen tube	15
3826084850	the fusion of gametes, occurs after the two sperm reach the female gametophyte	fertilization	16
3826095038	One sperm fertilizes the egg, and the other combines with the two polar nuclei, giving rise to the triploid food-storing_______. This double fertilization ensures that endosperm only develops in ovules containing fertilized eggs	endosperm	17

3826187210	develop from a group of flowers called an inflorescence	multiple fruits	21
3826189436	contains other floral parts in addition to ovaries	accessory fruit	22
3826199756	separation of a parent plant into parts that develop into whole plants, is a very common type of asexual reproduction	fragmentation	23
3826203187	the asexual production of seeds from a diploid cell	apomixis	24
3826205972	Asexual reproduction is also called _______ _______ because progeny arise from mature vegetative fragments	vegetative reproduction	25
3826227650	species have staminate and carpellate flowers on separate plants	dioecious	26
3826230448	plant's ability to reject its own pollen	self-incompatibility	27
3826251149	those that can divide and asexually generate a clone of the original organism, are common in plants	totipotent	28
3826255085	mass of dividing, undifferentiated totipotent cells that forms where a stem is cut and produces adventitious roots	callus	29
3826265374	______ organisms are those that have been engineered to express a gene from another species	transgenic	30
