Stigma is usually found at the tip of the style, the portion of the carpel that receives pollen (male gametophytes). It is commonly sticky or feathery to capture pollen.
The style in a flower is a pillar-like stalk through which pollen tubes grow to reach the ovary. Styles are always tube-like — either long or short. The style can be open (containing few or no cells in the central portion) or closed (densely packed with cells throughout). Pollen tubes grow the ...
Ovary is the structure at the bottom of the carpel which produces ovules internally (the "female" part of the flower). It is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at ...
A carpel is the ovule and seed producing reproductive organ in flowering plants. It consists of an ovary, a style and a stigma.
Petal is the next whorl toward the apex, composed of units called petals, which are typically thin, soft and colored to attract animals that help the process of pollination.
Sepal is the outermost whorl of the flower consists of units called sepals; these are typically green and enclose the rest of the flower in the bud stage, however, they can be absent or prominent and petal-like in some species.
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. ...
Chilled brood is not actually a disease but can be a result of mistreatment of the bees by the beekeeper. It also can be caused by a pesticide hit that primarily kills off the adult population, or by a sudden drop in temperature during rapid spring buildup.
