What holds the anther in place?
The thecae or microsporangium consist of microspores. Due to the presence of four microsporangium, an anther is also called “ Tetramicrosporangiate ”. An epidermis forms the outer lining and protects the anther. On maturation, the microsporangium develops “ Archaesporial cells ”.
What does the anther contain in a plant?
The anther contains, bears and produces pollen grains or pollens that are like the sperm of a flower for fertilization. The stigma on the other hand receives this pollen grain and the compatible ones reach the ovary allowing germination and reproduction. Since the anther of a flower contains pollen grains it is grainy in texture and feels.
What is the difference between anther and stamen?
is that anther is (botany) the pollen-bearing part of the stamen of a flower while stamen is (botany) in flowering plants, the structure in a flower that produces pollen, typically consisting of an anther and a filament. Other Comparisons: What's the difference? (botany) The pollen-bearing part of the stamen of a flower.
What does the name anther mean?
What Does Anther Mean? In plants, anthers refer to the parts of the plant’s stamen which produce pollen. Borne on the plant’s stalk, anthers are commonly attached to the middle area or base of the filament. These tend to be two-lobed and contain four distinctive microsporangia.
What is the description and function of anther?
The anther is a key structure in the reproduction of flowering plants. It sits atop the filament of the male structure known as the stamen. It produces the male sex cells, stores them, and provides a place for them to stay until the time is right for them to be dispersed.
How would you describe anther?
The male reproductive part of a flower is known as the stamen. It comprises a long tube, the filament, and has a pollen-producing structure towards the terminal. This oval-shaped structure is called the anther.
What is the definition of anther in a plant?
Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower.
What is the function of anther and where is it located?
The anther is located on top of the stamen, the male reproductive part. The anther is a key part of the reproductive process of a flower. This is because it produces and houses pollen grains. Pollen grains are the male sex cells for the flower.
What is the structure of anther?
A typical anther is always a bilobed and dithecous structure. Theca is a chamber on the anther lobes. Usually, each lobe has two theca and is hence named as dithecous. The transverse section of the anther shows two microsporangia in each lobe.
What is the shape of anther?
Anther shapes are variously described by terms such as linear, rounded, sagittate, sinuous, or reniform.
Where is the anther?
You can see the anthers by looking at the parts which stick out from the middle of the flower and have pollen on them. The anthers are the oval structure on the end of the filament of the stamen.
What is the function of anther and filament?
The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
Is the anther of a flower male or female?
The male parts of the flower are called the stamens and are made up of the anther at the top and the stalk or filament that supports the anther. The female elements are collectively called the pistil. The top of the pistil is called the stigma, which is a sticky surface receptive to pollen.

What is the anther in botany?
Introduction to Anther. In botany, it is as important to study the parts and functions of the flower as it is that of plants. The anther is a part of a flower. Let’s start by learning the parts of a flower, pistil, stamen, receptacle, peduncle and sepal. To define anther, it is crucial to understand the reproductive parts of the flower.
Where is the anther located?
The anther is connected to the distal end of the filament and is also the main attraction for the pollinators like insects and animals. The stigma is also located in the distal end of the pistil and it definitely plays an important role via its texture and shape to hold and transport the grain.
What is the difference between anther and stigma?
Anther and stigma are the male and female reproductive parts of a flower respectively. The anther is part of the male reproductive system, androecium in a flower. The stigma is part of the female reproductive system, gynoecium in a flower.
How do stamens work?
As understood from the above diagram, stamens are separated but all connected and collectively the stamens are called androecium. A filament of the stamen very diligently holds the anther on top and facilitates its functions. The filament holding the anther is attached to the petal, and the nature of the stamen solely depends on the type of the plants and flowers. The plants that reproduce through self-pollination which is via the transfer of the pollen from the anther to the stigma of the pistil to reach the ovary of the same flower of the same plant has the stamen bent towards the pistil. In the case of plant reproduction via cross-pollination that is the stigma receives the pollen from flowers of other plants via various means like insects and wind the stamen is usually bent away from the pistil.
What is the anther of a flower?
Ans. The anther of a flower is a part of the male reproductive system stamen. It is held above by the long tube called the filament. The anther of a flower is grainy as it produces and bears the pollen grains. The pollen grains transfer to the stigma of the flower to reach the ovary and fertilizes for reproduction to start. The anther that produces pollen in a way acts like the sperm so can be considered a part of the male anatomical reproductive system of a flower.
How many lobes does the anther have?
The anther which is the fertile part of the stamen usually has two lobes or thecas connected by a connective. Each lobe contains two pollen chambers longitudinally placed. Each chamber filled with pollen or pollen grains is also called microspores and hence these chambers are also called microsporangium.

The pollen-bearing part at the upper end of the stamen of a flower. Most anthers occur at the tip of a slender, stemlike filament and have two lobes. Each lobe contains two pollen sacs. When pollen matures in the pollen sacs, the lobes of the anthers burst open in the process known as dehiscence to release the pollen. See more at flower.

What are the two parts of the male reproductive part of angiosperm?
The stamen is the male reproductive part of an angiosperm and can be broken into two different parts: the filament and the anther. While the male reproductive part includes the male reproductive cell, pollen, the female reproductive part is called the pistil. The pistil can be broken into three main parts: the stigma, style, and ovary. The pistil also contains the female reproductive cell called the ovule.
