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 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.
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.
What are the similarities and differences between cones and flowers?
they are similar because they both have seeds and sharp hair
Does stamen produce pollen?
Pollen

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 produced in the male reproductive structures (microsporangia) of plants and develop into male gametophytes, while megaspores are produced in the female reproductive structures (megasporangia) and develop into female gametophytes. Microspores are smaller in size compared to megaspores.

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.

Is a stamen the site where microspores are produced?
Yes, a stamen is the male reproductive organ of a flower that produces pollen grains containing microspores. The microspores develop into male gametophytes.
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 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.
What is heterospory?
Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. Heterospory was evolved from isospory independently by several plant groups in the Devonian period as part of the process of evolution of the timing of sex differentiation. Heterosporic plants produce small spores called microspores which either germinate to become male gametophytes or have reduced male gametophytes packaged within them, and similarly larger spores called megaspores that germinate into female gametophytes, or which have female gametophytes packaged within them.
What are homosporous plants?
Heterosporous plants are those that produce two types of spores that differ in size and sex. In particular, they produce two morphologically distinct types of sporangia (megasporangia and microsporangia) that create two distinct types of spores (megaspores and microspores). The spores then develop into separate male and female gametophytes. They are different from homosporous plants in which the sporophyte produce a single type of sporangium and then a single type of mother spore cell.
