Alternation of Generations
It is also known as alternation of phases or metagenesis. This is the cycle of reproduction in which a haploid gametophyte alternates with a diploid sporophyte.
Words To Remember
Sorus
It is the cluster of sporangia.
Sporangium/Sporangia
It is an enclosure in
which spores are formed.
Gametophyte (Prothallus)
It is the haploid, multicellular phase of plants and algae that undergo
alternation of generations, with each of its cells containing
only a single set of
chromosomes.
Sporophyte
It is the diploid form of plants that have alternation of generations. It develops from a zygote and produces asexual spores.
Rhizoids
These are thread-like growths from the base or bottom of a plant,
found mainly in lower
groups such as algae,
fungi, bryophytes and
pteridophytes, that
functions like roots
of higher plants.
Antheridium
It is a haploid structure or organ producing and containing male gametes called sperm.
Archegonium
It is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete.
