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

Lycopods produce sporangia which are produced on the upper surface of modified leaves termed?
sporophylls
Where are sporophylls found?
Sporophyte is the phase in which diploid plant body gradually grows and produces spores through a process called meiosis. It is a dominant phase.
What is a flower lacking BOTH carpels and stamens?
A flower without stamen is known as a unisexual flower. And even a flower without pistel/carpel is known as unisexual flower. A flower is known as bisexual if it contains both stamen and pistel/carpel
Where are the reproductive organs of gymnosperms found?
In the male & female cones or sporophylls

What is telomes?
"a hypothetical plant structure in a theory of the evolution of leaves and sporophylls in vascular plants that consists of one of the vegetative or reproductive terminal branchlets of a dichotomously branched axis" Merriam-Webster
The leaves of ferns are called?
The leaves of ferns are called fronds. As a young frond unwinds and opens, it is called a fiddlehead. The regular fronds are called trophophylls. The fronds that produce spores are called sporophylls.

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 types of plants have reproductive structures on cones?
Coniferous trees bear cones such as pine trees, fir trees, and spruce trees...Pine trees bear pine cones.Conifers; Coniferous plants
How are pine cones important to your environment?
They make lovely blaze when you put them on the fire
Does a pine tree reproduce with leaves roots or stems?
Pine trees have seeds in the cone. Ferns are the only plants that I can think of off hand that have spores (I'm sure that there are more out there). Otherwise, if it is a natural plant, one that was not created from grafting/hybridization and so on, it has seeds.
