Question

Why do we say that sporophyte of anthocerotae shows many advanced characters suitable for land environment

Answer 1

In Anthoceros sporophyte is represented by foot, meristematic zone and capsule. The sporophyte produces the spores in the capsule. The spores on germination produce the gametophyte. So, in Anthoceros, two morphologically distinct phases (haplophase and diplophase) constitute the life cycle.Anthoceros is a genus of hornworts in the family Anthocerotaceae. ... Its name means 'flower horn', and refers to the characteristic horn-shaped sporophytes that all hornworts produce.The reason they are called hornworts is because of their reproductive structures or “sporophytes.” Similar to their moss and liverwort cousins, hornworts undergo an alternation of generations in order to reproduce sexually

Answer 2

• In Anthoceros, the sporophyte is represented by a bridge, a meristem zone, and a capsule.
• The sporophyte produces spores inside the capsule. Germinated spores form gametes.
• Thus, in Anthoceros, two morphologically distinct phases (haplophase and diplophase) constitute the life cycle.
• Sporophyte is a diploid, multicellular spore- producing phase in the life cycle of the factory body which exhibits alternation of generations.
• This structure starts from a diploid zygote, and this produces haploid spores by means of meiotic division.
• This sporophyte phase is the dominant phase in numerous vascular shops.
• The most characteristic features of this group are: Plant gametophytes are thallus and dorsolateral.
• Rhizoids are simple, with smooth walls.
• Complete absence of tuberculous rhizoids and abdominal scales. Thallus tissue is not differentiated.
