Most commonly anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther.
Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament. An anther and its filament together form a typical (or filantherous) stamen, part of the male floral organ. The typical anther is bilocular, i.e. it consists of two thecae.
The anther is the fertile part of the stamen and usually consists of two distinguishable, contiguous parts, called thecae, joined by an area called the connective, which is also where the anther joins the filament. It is usually formed by two thecae, sometimes it can be constituted by a single theca as in malvaceae and cannaceae or by three in ...
The disk floret is bisexual with female parts (one pistil containing one style, two stigmas, and an ovary with one ovule) and male parts (stamen, anthers, and filaments). Labeled parts are as follows: 1 – two stigmas, shown opened (if closed, they would appear as an extension of the style); 2 – style; 3 – five anthers fus...
The male stamen is inside the tube-shaped corolla of the disk floret. It has five anthers, five filaments, and produces pollen. The anthers and filaments are readily visible as separate entities in non-Asteraceae species. Here, they are fused together to form a cylinder, or tube, with their pollen on the inside only.
It is derived from the fusion of both male and female parts (stamens and pistil) into a single organ. [1] The top part of the column is formed by the anther, which is covered by an anther cap. This means that the style and stigma of the pistil, with the filaments and one or more anthers, are all united.
Compared to the other parts of the cytoskeletons, the microfilaments contain the thinnest filaments, with a diameter of approximately 7 nm. Microfilaments are part of the cytoskeleton that are composed of protein called actin. Two strands of actin intertwined together form a filamentous structure allowing for the movement of motor proteins.
Human anatomy is the study of the shape and form of the human body. The human body has four limbs (two arms and two legs), a head and a neck, which connect to the torso. The body's shape is determined by a strong skeleton made of bone and cartilage, surrounded by fat (adipose tissue), muscle, connective tissue, organs, and
