Is Cycas a non Archegoniate?

Cycas is an archegoniate plant, in which female gametophyte contains archegonia. The archegonia are formed from the gametophytic cells lining the archegonial chamber. The number of archegonia formed in a gametophyte is variable among species.

Is a cycad a gymnosperm or angiosperm?

Cycads are gymnosperms (naked seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle.

Which type of leaves are present in Cycas?

There are two types of leaves – foliage leaves and scaly leaves. The foliage leaves are pinnate (or more rarely bipinnate) and arranged spirally, with thick and hard keratinose. They are not permanent and fall off leaving back leaf-bases. The leaflets are articulated, have midrib but lack secondary veins.

What is the difference between male and female Cycas?

The female strobilus in the genus Cycas is by far the most primitive and allows you to easily determine its leafy origin (Foster, 1974). To distinguish between males and females, observe the cone as it is emerging. The male cone is more slender and possesses more and smaller sporophylls (cone scales).
