Question

In Selaginella when sporophyte develops directly from female gametophyte other than oosphere, the condition is called
A) Apospory
B) Aplanospory
C) Apogamy
D) Cleistogamy

Answer 1

In Selaginella when sporophyte develops directly from female gametophyte other than oosphere, the condition is called Apogamy

Answer 2

Answer:

   C) Apogamy is the correct option.

Explanation:

• Apogamy refers to the formation of 1n sporophytes without gametes, whereas syngamy refers to the formation of gametophyte vegetative cells.
• Because of disruptions in cytological events, the 2n aposporous gametophytes, and 1n apogamous sporophytes are generally infertile.
• Apospory is the growth of 2n gametophytes from vegetative, or non - reproductive, sporophyte cells without meiosis or spores.
• Apogamy happens more commonly in pteridophytes, whereas apospory occurs more frequently in bryophytes.
