What do micro spores develop into?
Each microspore can develop into a male gametophyte,or pollen grain
What happens to a megaspore mother cell and a microspore mother cells as an immediate result of meiosis?
The megaspore mother cell undergoes meiosis to produce four haploid megaspores, while the microspore mother cell undergoes meiosis to produce four haploid microspores. This division results in the formation of haploid spores that will develop into gametophytes in plants.
What structure developes into pollen grain?
Microspore
How does pollen grain compare to a microspore?
A pollen grain is a mature microspore that consists of two cells (generative cell and tube cell) enclosed within a protective wall. A microspore is a haploid cell produced in the sporangia of seed plants that eventually develops into a pollen grain through the process of microsporogenesis.
A mature microspore that contains a microgametophyte?
pollen grain
What kind of spore becomes a pollen grain in seed plants?
The microspore after resulting from meiosis in the microspore mother cell become pollen grain. It takes place inside the anther lobe in the sporogenous tissue and the entire process is called microsporogenesis.
What is a micro spore?
A microspore is is a part of heterosporous spore production, in which two types of sporophylls develop into two kinds of spores (eventually eggs and sperm). Microspores later develop in male gametophytes (sperm). Microspores start out as microsporangia in microsporophylls that later become microspores.
Do Angiosperms have spore?
Yes, angiosperms have two types of spores. They have both a male (microspore) and a female (megaspore).
What is the process of pollen production?
Pollen is produced in the anthers of flowers through a process called microsporogenesis. It begins with the division of microspore mother cells, which then undergo meiosis to produce haploid microspores. These microspores further develop into pollen grains, which contain the male gametes necessary for plant reproduction.
Is a pollen grain spore?
No, a pollen grain is not a spore. A pollen grain is a male gametophyte produced by seed plants for the purpose of reproduction, while a spore is a reproductive cell that can develop into a new organism without the need for fusion with another cell.
Pollen grains develop in what?
Pollen grains are often called as microspores or male gametes. They are produced in pollen sacs present in pollen chambers in the anthers of the flower. They are produced due to repeated division of microspore mothercells and are haploid (n).
What is the function of the spore of gymnosperms?
The gymnosperms produce megaspores and microspores. A microspore is the male spore and megaspore is the large female spore. The microspore undergoes mitosis to produce the multicellular male gametophyte. These male gametophytes are the pollen grains that are contained inside short pollen cones. The megaspore is the large female spore that undergoes mitosis to produce the multicellular female gametophyte that is housed in a large female cone.
