Angiosperms (flowering plants) have locules, which are chambers that are usually found within the ovary (gynoecium or carpel) that contain the flowers and fruits. Fruits can be classified as unilocular , bilocular, trilocular , or penta-locular depending on the number of locules present in the ovary. An individual gynoecium may have an equal or less number of locules than the number of carpels present in the uterus. The ovules or seeds are contained within the locules.
Additionally, pollen-containing chambers within anthers may be referred to as pollen sacs. Ascomycete fungi have locules, which are chambers within the hymenium in which the perithecia develop and grow.
Example of penta-locular ovary: china rose flower.
Pentalocular ovule diagram:
In botany, an ovary is an enlarged basal portion of the pistil, which is the female organ of a flower, that contains the egg. The ovary contains ovules, which are fertilised and develop into seeds as a result of the fertilisation process. The ovary will mature into a fruit, which will be either dry or fleshy in texture, and will contain the seeds.
A simple or unicarpellate ovary is formed from a single carpel, which is a leaf that has undergone evolutionary modification. It has a single locule (chamber) in which the ovules are contained. A multi carpellate ovary consists of more than one carpel and may contain one or more locules, depending on the species.
The position of the ovaries is a useful characteristic in classification. When an ovary is attached above other floral parts, it is referred to as superior; when it is attached below other floral parts, it is referred to as inferior.
Each flower is composed primarily of a floral axis, which bears the essential organs of reproduction (stamens and pistils) and, in some cases, additional accessory organs (petals and sepals), the latter of which may serve to both attract pollinating insects and protect the essential organs.
Unlike vegetative stems, which bear leaves, the floral axis is greatly modified; it is usually contracted, resulting in the parts of the flower being crowded together at the stem tip, known as the receptacle. It is common for the flower parts to be arranged in whorls (or cycles), but they can also be arranged spirally, especially when the axis is elongated.
Typically, there are four distinct whorls of flower parts: (1) an outer calyx, which is composed of sepals; (2) the corolla, which is composed of petals; (3) the androecium, which is composed of stamens; and (4) the gynoecium, which is composed of pistils.
Pentalocular ovary in malvaceae species:
Racemose or a cymose inflorescence is found in the leaf axil or in the leaf axils of the plant.
Blooming flower: a bracteate or bracteolate bloom, actinomorphic in appearance, dichlamydeous, complete, pedicellate, heterochlamydeous bisexual, pentamerous, and hypogynous bloom, and mucilage in floral structures.
Calyx: green, usually with 5 sepals, gamosepalous with valvate aestivation, and the odd sepal is positioned posteriorly in the arrangement.
Epicalyx: a whorl of bracteoles on the surface of the calyx that forms an additional calyx-like whorl. To the outer calyx, there are 5-8 bracteoles that are free and green. The number of bracteoles differs from species to species.
Flowers: Petals 5, with a polypetalous bust basally adnate to the staminal column, variously coloured, twisted aestivation at the base of the staminal column.
Androecium: number of stamens, monadelphous, filaments fuse to form a tubular staminal column around the gynoecium, anthers reniform, monothecous, extrorse dehiscing transversely or longitudinally, anthers reniform, monothecous, extrorse dehiscing transversely or longitudinally, anthers reniform, monothecous.
Gynoecium: long and simple in design, slender in appearance as it passes through the staminal tube. Stigma 5, coloured and capitate, pentacarpellary syncarpous, ovary superior, ovary pentalocular with several oculi per locule on the axile placentation, pentacarpellary syncarpous, pentacarpellary syncarpous, pentacarpellary syncarpous, pentacarpellary syncarpous, ovary superior, ovary pentalocular with several oculi per locule Styles are divided into many stigmata, or twice as many as carpels are divided into stigmata.
Conclusion:
Angiosperms (flowering plants) have locules, which are chambers that are usually found within the ovary (gynoecium or carpel) that contain the flowers and fruits. Fruits can be classified as unilocular , bi-locular , trilocular , or penta-locular depending on the number of locules present in the ovary.Ascomycete fungi have locules, which are chambers within the hymenium in which the perithecia develop and grow.
