Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
Gynodioecy – describes a plant species or population that has some plants that are female and some plants that are hermaphrodites. Homogamous – when the flower's anthers and stigma are ripe at the same time. Imperfect – of a flower or inflorescence, being unisexual and having organs of only a single sex. [17]
Diagram showing the stigma-style-ovary system of the female reproductive organ of a plant. The stigma is fixed to the apex of the style , a narrow upward extension of the ovary . The stigma ( pl. : stigmas or stigmata ) [ 1 ] is the receptive tip of a carpel , or of several fused carpels, in the gynoecium of a flower .
In the flowering plants, an ovary 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 the point of connection with the base of the petals and sepals .
This chart shows the internal distribution of various viscera and organs from the back view. They include the stomach cavity, the lung, the stomach, the liver, the spleen, the [left] kidney, the mingmen (right kidney considered as 'Portal of Life'), the small and large intestine, etc. Wellcome Images
Location of ovules inside a Helleborus foetidus flower. In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.
Gynoecium (/ ɡ aɪ ˈ n iː s i. ə m, dʒ ɪ ˈ n iː ʃ i. ə m /; from Ancient Greek γυνή (gunḗ) 'woman, female' and οἶκος (oîkos) 'house'; pl.: gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds.
