What is the difference between microspores and megaspores?
microspores are the male gametes whilst megaspore are the female gametes. megaspore also known as megaspore mother cellor megasporocyte. it placed in female cone in the gumnosperm while the microspores placed in the male cone
What part of a plant makes pollen?
Pollen is produced in the Anther(s) of the plant; the anther and the filament (the portion which holds the anther) form what is know as the stamenThe stamen is the part of the flower that makes pollen. The anther is the part of the flower that holds the pollen grains.
What are the sturctures that produce the male gametophyte in angiosperms called?
The structures that produce the male gametophyte in angiosperms are called anthers. Anthers are located on the stamen of the flower and contain pollen sacs where microspores develop into pollen grains through meiosis and subsequent mitotic divisions.
Function of stamen?
The stamen is the male reproductive organ of a flower. It produces pollen, which contains the male gametes (sperm cells) necessary for plant reproduction. The stamen is composed of the filament, which holds up the anther where pollen is produced.
2 parts of the stameN?
The stamen is composed of two main parts: the anther and the filament. The anther is where pollen is produced, while the filament is the stalk that supports the anther and positions it for optimal pollen dispersal.
What are the male flower sexcells produced by?
Male flower sex cells, or pollen grains, are produced by the anthers, which are part of the stamen in flowering plants. The stamen consists of the filament and the anther, where the pollen is developed through the process of microgametogenesis from microspores. These pollen grains carry the male gametes necessary for fertilization in the reproductive process of plants.
The site of formation of pollen grains?
Pollen grains are formed in the anthers of the flower's stamen through a process called microsporogenesis. Within the anthers, specialized cells undergo meiosis to produce microspores, which then develop into pollen grains through a series of cell divisions and differentiation.
In what part of flowers is pollen produced?
The part which produces the pollen is called the stamen.
What is the main job of the stamen?
The main job of the stamen is to produce pollen, which contains the male reproductive cells of a plant. Pollen is essential for fertilizing the female reproductive organs of the plant to produce seeds.
What is the difference between microspores and megaspores?
microspores are the male gametes whilst megaspore are the female gametes. megaspore also known as megaspore mother cellor megasporocyte. it placed in female cone in the gumnosperm while the microspores placed in the male cone
Are microspores and megaspores produced by mitosis or meiosis?
Microspores and megaspores are produced by meiosis. In plants, microspores develop into male gametophytes (pollen), while megaspores develop into female gametophytes (embryo sacs). This process occurs in the reproductive structures of seed plants, where diploid sporophytes undergo meiosis to produce these haploid spores.
Does stamen produce pollen?
Pollen
Where is the male sex produced in the flower?
The stamen
In which part a flower is pollen produced?
the stamen
Where is the male sex cell produced in a flower?
The stamen
What is the male sperm produced by?
In a flower, the pollen is produced in the stamen, particularly the anther. The stamen is made up of a filament that supports the anther.
What part of a plant makes pollen?
