Differbetween
The main difference between megasporophyll and microsporophyll is that megasporophyll bears megasporangia, which produce megaspores, whereas microsporophyll bears microsporangia, which produces microspores. ... Megasporophyll and microsporophyll are the two types of sporophylls or the leaves which bear sporangia.

What is Microsporophyll and Megasporophyll?
Microsporophyll bears spores that grow into male gametophytes. The microsporophylls located just inside the petals, are the Stamens. Megasporophyll bears spores that grow into female gametophytes. The megasporophylls located just inside the stamens, are the Carpels.
What is a Microsporophyll?
(ˌmaɪkrəʊˈspɔːrəfɪl) n. (Botany) a leaf on which the microspores are formed: corresponds to the stamen of a flowering plant.
What is the difference between Microsporangium and Microsporophyll?
As nouns the difference between microsporophyll and microsporangium. is that microsporophyll is a leaflike organ that bears one or more microsporangia (contrast megasporophyll) while microsporangium is (botany) a case, capsule or container that holds microspores.

What does Megasporophyll produce?
Megasporophyll is a type of leaf-like structure produced by heterosporous plants such as seed plants, lycophytes, and some ferns. Generally, it produces megasporangia, sacs that produce megaspores of female spores. Moreover, in seed plants, ovule serves as the megasporangium.
What is a Megasporangia?
Megasporangia (female sporangia) produce megasporocytes (megameiocytes) that yield megaspores. The sporangia may be borne in specialized structures such as sori in ferns, cones (strobili) in some pteridophytes and most gymnosperms, or flowers in angiosperms.
Is anther a Microsporangium?
The male gametophyte develops and reaches maturity in an immature anther. In a plant's male reproductive organs, development of pollen takes place in a structure known as the microsporangium (Figure 5). The microsporangia, which are usually bi-lobed, are pollen sacs in which the microspores develop into pollen grains.
How many Microsporangias are in a Microsporophyll?
arrangement, reduced fertile leaves (the microsporophylls). On the lower surfaces of the microsporophylls are borne elongated microsporangia; two microsporangia per microsporophyll is common, but some genera have more.
Is Stamen a Microsporophyll?
The stamen (microsporophyll), is often called the flower's male reproductive organ. ... It is typically located between the central pistil and the surrounding petals. A stamen consists of a slender stalk (the filament) tipped by a usually bilobed sac (the anther) in which microspores develop as pollen grains.
Do pines have Archegonia?
Characteristics of the life cycle
The female and male inflorescence of the pine tree develop as cones on the sporophyte. ... The megaspore goes through mitotic divisions and forms a small female gametophyte, in which two or three archegonia are present, each with one egg cell.
What is the Megasporophyll in angiosperms?
A megasporophyll or carpel is rolled and partly sterilized to produce a stigma, style and ovary containing ovules. Within ovules are present highly reduced female gametophytes known as embryo sacs. Embryo sac formation is preceded by meiosis. So all the cells of embryo sac are haploid.
How many Microsporangia are present in an anther?
Angiosperm stamens have anthers with four microsporangia (pollen sacs), organized into two thecae basically in all clades (Endress and Stumpf, 1990).
