biological process through which living organisms produce offspring's similar to them
> single cell or organism produce new organism
> without the fusion of gametesÂ
> genetically the same with the parent
> fusion of gametes
> genetically different from the parent
> bending plant branches or stemsÂ
the transfer of pollen grain from an anther to a stigma.Â
> wind or animal-aided
> one sperm fuses with the central or polar nuclei (forming endosperm) and;
> one sperm fertilizes the egg (forming zygote)Â
> happens inside the ovary
> when the nucleus of pollen grain fuses with the nucleus of an ovule to produce zygote
ovary matures into fruit
ovule matures into _________
> involves pieces of stems cut from parent tree, and reproducing them as offspring
> a desired cutting is attached to the stem
> the act of placing a portion of one to another branch; a union will be formed
produce seeds without fertilization
asexual method of plant that occurs in its leaves, roots, and stem
Stems covered with leaves that can produce new plants
MODIFIED ROOTS
> enlarged structure used as storage organs for nutrients
> can produce new plants
mini plants that grows on the main plant and then fall and grow in to new plants
MODIFIED STEMS
> thicker stems that stores foodÂ
> produce buds which grow into new stems
horizontal stem that grows under the soil
horizontal stems that grows all over the soil surface
>aboveground vegetative portions (stems and leaves)
> reproductive parts (fruits and flowers)Â
includes roots and supports the plant and is usually underground
> made up of four (4) whorls
> reproductive structure in flowering plants
whorled arrangement of leaves, sepals, petals, stamens, or carpels
> (calyx)
> outermost whorls of flower
> (corolla)Â
> whorl inner to sepals
> brightly colored
male reproductive structure
> (carpel)Â
> female reproductive structureÂ
structure that produces megaspore=> female gametophyte=> egg cells
> part of pistil where the pollen grain derived from the microsporangium
part of the pistil that serves as the stalk of the stigma; leads to ovary
> found at the base of the pistil
> contains one or more ovule
> becomes fruit
> contains the female sporangia
> becomes the seed
structure that produce microspore=> male gametophyte=> sperm cellsÂ
part of the stamen that contains the microsporangia that develops into pollen grains
serve as the stalk of the Anther
