What else can I help you with?
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
Is selaginella a homosporous or a heterosporous plant?
Selaginella is a heterosporous plant, meaning it produces two types of spores – megaspores and microspores. Megaspores develop into female gametophytes, while microspores develop into male gametophytes.
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 do parietal cells and chief cells produce together?
Parietal cells produce cover cells and chief cells produce micro and megaspores
What is meant by monosporic development of female gametophyte?
The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte. In most flowering plants, a single megaspore mother cell present at the micropylar pole of the nucellus region of the ovule undergoes meiosis to produce four haploid megaspores. Later, out of these four megaspores, only one functional megaspore develops into the female gametophyte, while the remaining three degenerate
After meiosis how many megaspores survive?
After meiosis in plants, only one out of the four megaspores produced survives and develops into a female gametophyte. The other three megaspores disintegrate.
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
Are megaspores mother cells haploid?
no they are diploid
The seed plant spores that produce megagametophytes?
megaspores
Do nonvascular plants have pollen?
No, at the most, these have micro-spores and megaspores
Are all spores in the same sporangium similar?
no selaginella has megaspores and microspores
What type of spores do selanginella produces?
Selaginella plants produce spores called microspores and megaspores. Microspores give rise to male gametophytes, while megaspores develop into female gametophytes. These spores are produced in sporangia located on the underside of their reproductive structures called strobili.
What plants produce separate male and female cones that produce microspores and megaspores that develop into male and female gametophytes?
Gymnosperms, such as pine trees, produce separate male and female cones that produce microspores and megaspores. These microspores and megaspores develop into male and female gametophytes, which contain the sperm and egg cells for reproduction.
How many megaspores die if only four are produced?
If only four megaspores are produced, then three out of the four will typically die. This is because usually only one megaspore develops into a functional female gametophyte, while the others degenerate.
Is selaginella a homosporous or a heterosporous plant?
Selaginella is a heterosporous plant, meaning it produces two types of spores – megaspores and microspores. Megaspores develop into female gametophytes, while microspores develop into male gametophytes.
During sexual reproduction in a flowering plant four megaspores are produced and how many of them die?
three
What flowering plants becomes the female gametophyte?
In flowering plants, megaspores become the female gametophytes.
