Cards Term alternation of generations Definition haploid and diploid generations take turns in producing each other Term sporophyte Definition diploid plant that produces haploid spres by meiosis Term gametophyte Definition haploid sperm and eggs Term order of modified leaves from outside to inside Definition sepals petals stamens carpels Term complete clower Definition have sepals petals stamens carpels Term incomplete flowers Definition lack on or more of the four modiefied leaves Term perfect flower Definition have stamens and carpels Term monoeicious Definition stamen and carpel are on same plant Term dioecious Definition stamens and carpels on different plants Term microspores Definition form when microsporocytes go through meiosis. produces fenerative cell and tube cell. Term kegaspore Definition prodeced when megasporocute goes through meiosis. only one of the four produced survives. Term embryo sac Definition megaspore mass with eight haploid nuclei. the female gametophyte Term pollination Definition pollen goes on the stigma of the carpel Term self incompatible flowers Definition pollen grain from an anther lands on stigma of a flower on the same plant, biochemical block prevents fertilization Term endosperm Definition food storing tissue Term double fertilization Definition union of two sperm cells with different cell of the embryo sac. one sperm fertilizes egg to form zygote. other sperm combines with two poalr nuclei to form a triploid nucleus in the center of hte large central cell fo the embryo sac. Term seed coat Definition encloses embryo and food supply Term hypocotyl Definition embryonic axis below the pt where cotyledons are attached Term radicle Definition embryonic root Term epicotyl Definition embryonic axis above the cotyledons Term scutellum Definition specialized cotyledon in monocot seed. absorbs nutrients during fertilization Term colerhiza Definition sheath enclosing grass embryo covers root and coleoptile Term coleoptile Definition cloaks embryo shoot Term fruit Definition ovary Term pericarp Definition thickened wall of fruit Term simple fruit Definition derived form single ovary Term agreggate fruite Definition results of singe flower that has several carpels. ex: blackberry Term multiple fruit Definition developes form an inflorescence group of flowers tightly clustered together ex: pineapple Term imbibition Definition absorption of water due to low water potentail of dry seed Term fragmentation Definition seperation fo parent plant into parts that reform whole plants most common mode of vegetative reproduction Term apiximis Definition produce seeds without fertilized flowers Term callus Definition undifferentated dividing cells at the cut end of a shoot Term stock Definition plant tha provides the rood system Term scion Definition twig grafted onto stock Term monoculture Definition cultivation of of large areas of land with a single plant Term protoplast fusuin Definition being coupled with tissue culture nethods to actually invert new plant varieties that can be cloned Term cellular differentiation Definition aquisition of cell's specific structure Term morphogenesis Definition develipment of form Term preprophase band Definition ring of microtubles in the cell cortex Term pattern formation Definition development of specific structures in specific locations Term positional formation Definition signals that indicate each cell's location within an embryonic structure Term meristem identity genes Definition helps with the transition from vegetative growht to flowering
