Question

in contrast to moss vascular plants such as ferns have a dominant sporophyte. provide two advantages of having a dominant sporophyte as opposed to a dominate gametophyte

Answer 1

Answer:

Sporophyte is diploid multicellular stage that are found in plants, algae and helps in formation of zygote.

Explanation:

The seedless vascular plants bear dominant sporophytes over generation like clubmoss,ferns etc.

The leaves are dotted with sporangia which are in cluster form.

The sporangia helps in formation of gametophytes that contain antheridia and archegonia.These structures are important as they produce sperm with multiple cilia bearing on it and eggs.

The individuals that are produced live long and grow in larger size.

The individuals produce more oxygen as they contain chlorophyll.They produce carbohydrate rich food by the process of photosynthesis.

Answer 2

Dominant sporophyte

Explanation:

All plants have a life cycle in which they undergo alternation of generations,this process involves a haploid multicellular generation called a gametophyte and a diploid multicellular generation called a sporophyte

• Haploid means having only one set of chromosomes in cells and is usually written as n whereas diploid means having two sets of chromosomes and is indicated by 2n
• A sporophyte is created by sexual reproduction of the gametophyte generation
• In the most primitive plants, like mosses, the gametophyte is dominant (i.e. it's big and green)whereas in higher plants like ferns and fern allies, the sporophyte stage is dominant
• It is beneficial to have the sporophyte generation dominant in vascular plants because the sporophyte generation has the vascular tissue
• The sporophyte generation is photosynthetic and is independent of the gametophyte,the sporangia are protected by a layer of cells called the indusium and the entire structure is called a sorus
