Flower anatomy

Flowering plants are heterosporangiate and the pollen and ovules are produced in different organs, but these are together in a bisporangiate strobilus that is the typical flower.

A flower is regarded as a modified stem with shortened internodes and behavior, at its nodes, structures that may be highly adapted leaves. In essence, a flower structure forms on a modified shoot or axis with an apical moisten that does not grow constantly. The stem is called a pedicel, the end of which is the tours or container. The parts of a flower are arranged in whorls on the tours. The four main parts or whorls are as follows:


Poppy calyx – the outer whorl of sepals; naturally these are green, but are petal-like in some species.
Corolla – the whorl of petals, which are usually thin, soft and colored to be a focus for insects that help the process of pollination.
Androecium’s– one or two whorls of stamens, each a filament topped by an anther where pollen is produced. Pollen contains the male gametes.
Gynoecium’s – One or more pistils. The female reproductive organ is the carpel: this contains an ovary with ovules. A pistil may consist of a number of carpels merged together, in which case there is only one pistil to each flower, or of a single individual carpel. The sticky tip of the pistil, the stigma, is the receptor of pollen. The supportive stalk, the style becomes the pathway for pollen tubes to grow from pollen grains adhering to the stigma, to the ovules, carrying the reproductive material.

God and his attributes:

God most normally refers to the holy being worshipped by followers of monotheistic and monolatrist religions, whom they accept as true to be the creator and ruler of the world.

Theologians have ascribed various attributes to a variety of conceptions of God. The most ordinary among these consist of omniscience, perfect goodness, omnipotence, omnipresence, divine simplicity, and everlasting and necessary existence. God has also been conceived as being incorporeal, a personal being, the source of the entire moral obligations, and the "greatest conceivable existent". These attributes were all supported to varying degrees by the early Christian, Jewish and Muslim theologian philosophers, including Augustine of Hippo, Al-Ghazali, and Maimonides. Many famous medieval philosophers developed arguments for the existence of God, attempting to fight with the obvious contradictions implied by many of these attributes.
