Gametophyte - Plant that produces gametes by mitosis

Gametangia (from Zygomycota)

Heterocyst

Heterosporous: the condition in vascular plants of bearing two types of spores - Microspores become male gametophytes, megaspores become female gametophytes (all seed plants are heterosporous).

In Selaginella

Homosporous: the condition in vascular plants of bearing only one type of spore. These spores bear bisexual gametophytes

Hyphae

Mega- (prefix denoting femaleness in heterosporous plants)

Megagametophyte = female gametophyte in vascular plants

Megasporangiate strobilus (female cone) in Pinus

Megasporangium ( From Selaginella with Megasporyphyll) (Image)

The Nucellus of seed plants is a megasporangium - see nucellus

Megaspore - Example from Selaginella

Megaspore Mother Cell: A diploid cell that undergoes meiosis to produce a megaspore: in seed plants will be viewed in the nucellus of a young ovule.

Megasporophyll

Microphyll (xs of Lycopodium ): type of leaf in the Lycophyta having only one vein and is not associated with a leaf gap

Micro- (prefix denoting maleness in heterosporous plants)

Microgametophyte

Microsporangium

Microspores

Microsporophyll

  • View of dissected male strobilus of Pinus
  • Stamens of flowering plants are microsporophylls
