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.
Are all spores in the same sporangium similar?
no selaginella has megaspores and microspores
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.
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
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 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.
Compare the male and female spores of a conifer?
The female spores of a conifer are called megaspores or macrospores. Megaspores develop into a female gametophyte, producing egg cells. Male spores of a conifer are called microspores and are formed from meiosis. Microspores develop into the male gametophyte, which produces sperm cells.
What plants produce separate make and female cones that produce microspores and megaspores that develop into make and female gametophytes?
Plants that produce separate male and female cones, producing microspores and megaspores, are primarily gymnosperms, particularly conifers such as pines, spruces, and firs. In these plants, male cones generate microspores that develop into male gametophytes (pollen), while female cones produce megaspores that develop into female gametophytes, which contain the ovules. This reproductive strategy allows for the efficient production of gametes and subsequent fertilization in a wind-pollinated environment.
Why is heterospory considered an important step towards seed habit?
Heterospory is important for the evolution of the seed habit because it allows for the production of two distinct types of spores - microspores and megaspores. Microspores develop into male gametophytes while megaspores develop into female gametophytes. This separation of male and female gametophytes is a key feature in the development of seeds and is more efficient for reproduction than homospory.
Haploid reproductive cells are called?
The four cells formed as a result of meiosis are called daughter cells.
What is the ploidy level of the micropyle?
The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
What is the difference between megasporangia and microsporangia?
feature mega micro size large small produce megaspore, microspores female gametophyte male gametophyte no.pf spores 4 megaspores numerous microspores
