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
What is the function of the spore of gymnosperms?
The function of the spore in gymnosperms is to serve as a reproductive structure that can develop into a gametophyte. The spore undergoes mitotic division to produce a multicellular gametophyte, which then produces the gametes (sperm or eggs). The fusion of these gametes gives rise to the development of the next generation of gymnosperms.
How does a sporangiophore function in the reproduction of fungi?
Microspores develop inside the microsporangium
What is formed from gametophytes?
A spore. The gametophyte makes gametes, which fertilize to form a zygote. That zygote develops into a sporophyte, which makes spores through meiosis. Those spores will then develop into the gametophyte.

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 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.
Does stamen produce pollen?
Pollen
What males spores that will develop into pollen grains?
microspores
What are male spores that develop into pollen grains?
microspores
The spores that plants produce develop into?
gametophytes
Where does megasporangia take place?
Megasporangia are structures that produce megaspores, which are involved in the formation of female gametophytes in seed-producing plants such as gymnosperms and angiosperms. Megasporangia are typically located within the ovules of the plant's reproductive structures, where they develop into megagametophytes during the process of seed formation.
Were is pollen made?
Gymnosperms are heterosporous, producing microspores that develop into pollen grains and megaspores that are retained in an ovule. After fertilization (joining of the micro- and megaspore), the resulting embryo, along with other cells comprising the ovule, develops into a seed. The seed is a sporophyte resting stage.
What is the function of the spore of gymnosperms?
The function of the spore in gymnosperms is to serve as a reproductive structure that can develop into a gametophyte. The spore undergoes mitotic division to produce a multicellular gametophyte, which then produces the gametes (sperm or eggs).
