What is Megasporophyll in gymnosperms?

The megasporophyll is a sporophyte that contains megasporangium in gymnosperms. On the other side, the carpel is the female reproductive organs in flowers. The male reproductive organ is known as stamen which is composed of anther and filament. It produces male gamete or pollen grain.

What are Megasporophyll and Microsporophyll?

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 are characteristics of gymnosperms?

Characteristics of Gymnosperms

What is the structure of gymnosperms?

Gymnosperms are flowerless plants that produce cones and seeds. The term gymnosperm literally means "naked seed," as gymnosperm seeds are not encased within an ovary. Rather, they sit exposed on the surface of leaf-like structures called bracts.

What is the meaning of Megasporophyll?

megasporophyll in British English

(ˌmɛɡəˈspɔːrəfɪl ) a leaf on which the megaspores are formed: corresponds to the carpel of a flowering plant.

What is Sporophyllus?

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 and are called microsporophylls.

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 is the function of Microsporangium?

Microsporangia are sporangia that produce microspores that give rise to male gametophytes when they germinate. Microsporangia occur in all vascular plants that have heterosporic life cycles, such as seed plants, spike mosses and the aquatic fern genus Azolla.

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.

What is the function of gymnosperms?

Uses. Gymnosperms have major economic uses. Pine, fir, spruce, and cedar are all examples of conifers that are used for lumber, paper production, and resin. Some other common uses for gymnosperms are soap, varnish, nail polish, food, gum, and perfumes.

What is unique about gymnosperms?

As you can see, gymnosperms are a unique group of plants. They do not have bright flowers to show off or sweet delicious fruits enclosing their seeds. Instead, they have naked seeds that are found in cones or on short stems. They are the most primitive of seeds plants and can live in a variety of environments.
