Oophorectomy (/ ˌ oʊ. ə f ə ˈ r ɛ k t ə m i /; from Greek ᾠοφόρος, ōophóros, 'egg-bearing' and ἐκτομή, ektomḗ, 'a cutting out of'), historically also called ovariotomy, is the surgical removal of an ovary or ovaries. [1] The surgery is also called ovariectomy, but this term is mostly used in reference to non-human ...
A pistil typically consists of an expanded basal portion called an ovary, an elongated section called a style and an apical structure called a stigma that receives pollen. The ovary (from Latin ovum, meaning egg) is the enlarged basal portion which contains placentas, ridges of tissue bearing one or more ovules (integumented megasporangia). The ...
The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae , the cells of which are receptive to pollen.
In flowering plants, the central axis of the cone or fruit, e.g. in Callitris. column 1. A structure extending above the ovary and incorporating the style and stamen s also known as the gynostegium, e.g. in orchids and milkweeds. 2. In grasses, the lower, stouter, and usually twisted part of an awn, distinct from the slender upper part or bristle.
See Ovule#Location within the plant. An obturator is present in the ovary of some plants, near the micropyle of each ovule. It is an outgrowth of the placenta, important in nourishing and guiding pollen tubes to the micropyle. [17] The ovary of some types of fruit is dehiscent; the ovary wall splits into sections called valves. There is no ...
If the ovary is located above the point of insertion, it will be subterranean; if it is below, it will be infertile. The seminal rudiment, also called the ovule , is the plant organ that forms in the ovary and contains the embryo sac within which are the oosphere or female gamete, the synergid cells, the median cell with the two polar nuclei ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
Pollen itself is not the male gamete. [4] It is a gametophyte, something that could be considered an entire organism, which then produces the male gamete.Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell.
