The cell which is formed from the amra of the uterus and becomes a seed after fertilization is called an ovule. The ovary contains the ovum.
Ovaries are of 4 types based on location.
- Orthotropous ovary: The ovary in which the umbilicus, follicle and oviduct are in a straight line and the oviduct is at the top is called an orthotropous ovary. For example – betel nut, water pepper (Polygonum orientale), pepper (Piper nigram) etc.
- Anatropous Ovary: An ovule in which the ovule is above, the oviduct is below and the umbilicus is next to the oviduct is called Anatropous ovary. Such as beans, radish, peas, chickpeas (Cicer arietinum) etc.
- Lateral ovule (Amphitropous): The ovule which is attached perpendicularly to the pedicel and the ovule and ovule are oppositely located is called amphitropous ovule. For example – Poppy (Opium), Khudipana, China Pink (Dianthus chinensis), Sagittaria sagittifolia etc.
- Campylotropous Ovary: Campylotropous ovum is called campylotropous ovary. For example – Kalkasunda (Cassia sophera), Mustard (Brassica nigr) etc.
- Semi-anatropous ovary: Semi-anatropous ovary is horse shaped. For example, Palik, Chhotakut etc.
