What is sporophylls?
A sporophyll is a leaf that bears sporangia. Both microphylls and megaphylls can be sporophylls. In heterosporous plants, sporophylls (whether they are microphylls or megaphylls) bear either megasporangia (and thus are called megasporophylls), or microsporangia (microsporophylls). The overlap of the prefixes and roots makes these terms a particularly confusing subset of botanical nomenclature
What is pollen cone?
It's a lot of pollen, shaped as a cone... JKThe male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small ways (mostly in scale arrangement) from species to species. Extending out from a central axis are microsporophylls (modified leaves). Under each microsporophyll is one or several microsporangia (pollen sacs).
What does stamen look like?
Stamen typically consist of a stalk and an anther, this is according to Wikipedia. Stamen is the pollen producing reproductive organ of any particular flower.
What does bioligist mean?
it mean that you are healthy
What is mean by toes?
toes mean your mom
What is plural of microsporangium?
microsporangia
What part holds the pollen?
The stamen, or to be more specific, the microsporangia.
Which part of the flower is a male sex cell?
Microsporangia in the anther lobe of the stamen
What part of the plant Holds the anther high?
The stamen, or to be more specific, the microsporangia.
What is the anther filled with?
i don't rightly know OK don't judge me stop it your making me cry OK stop ...
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.
What does stamen look like?

What are the internal parts of the stem and their functins?
A stamen is generally consists of a filament and an anther lobe. Inside the anther lobe are the microsporangia where microspores are produced as a result of meiosis. Each microspore on maturity becomes a pollen grain. Wall of the microsporangium have several layers such as the epidermis, endothecium, middle layers and the tapetum. The tapetal cells nourish the developing pollen grains, middle layers are consumed by the tapetum and the endothecial cells on maturity help in the dehiscence of the anther lobes to release pollen grains.
