What is sporophyte development?

What is sporophyte development?

Sporophytes develop from a fertilized egg, or zygote, that results from the fusion of gametes (fertilization) formed by the gametophytes and are accordingly diploid; i.e., each cell has two sets of chromosomes.

What is apogamy and Apospory?

Apospory. Meaning. Apogamy is an asexual method of reproduction in plants where the gametophyte develops from the sporophyte. Apospory is also an asexual method of reproduction where sporophyte develops from the gametophyte.

What is apogamy in plants?

1. a type of reproduction, occurring in some ferns, in which the sporophyte develops from the gametophyte without fusion of gametes. 2. the development of a diploid cell in the embryo sac of flowering plants into an embryo without being fertilized.

Where does the sporophyte develop?

The embryonic sporophyte develops within the archegonium, and the mature sporophyte stays attached to the gametophyte. The sporophyte is not photosynthetic. Thus both the embryo and the mature sporophyte are nourished by the gametophyte.

What is the function of sporophyte?

Sporophyte is the diploid phase in the life cycle of a plant. It produces spores by meiosis that give rise to haploid gametophytes.

What is the difference between Diplospory and apospory?

In diplospory, the egg apparatus is formed from a nucleus cell other then the mother cell by mitotic division. the egg forms the zygote without fertilisation. In apospory, the egg apparatus is formed from a cell other than nuclleus cells .

What is the difference between apogamy and parthenogenesis?

Parthenogenesis refers to development of embryo from the egg cell without fertilization. 2. Apogamy. The origin of embryo from either synergids or antipodal cells of the embryosac is called as apogamy.

What is the difference between parthenogenesis and apogamy?

What is the difference between apogamy and apomixis?

In apomixis a meiotic division is suppressed, and a single division produces diploid offspring. In apogamy development of a sporophyte from a gametophyte without fertilization.

What event begins the sporophyte life cycle?

Fertilization occurs in the archegonium of both liverworts and mosses. What event begins the sporophyte phase of the life cycle? Where does this event occur in liverworts and mosses? Meiosis and spore formation in the sporangium.

When the plant sporophyte develops to undergo maturation it produces?

So, the correct answer is ‘Sporophyll’

What are the characteristics of a sporophyte?

Characteristics of Sporophytes The sporophyte is diploid and has a multicellular structure, which means it contains two sets of chromosomes, one from each parent. They will undergo meiotic division (asexual mode of reproduction) and give rise to meiospores.

What is Diplospory?

: reproduction by means of unreduced spores.

What is apospory and apogamy in bryophytes?

In this regard, apogamy and apospory refer to two asexual modes of reproduction in plants such as bryophytes. Apospory refers to the production of a diploid gametophyte from a diploid sporophyte. In contrast, apogamy refers to the process of developing a haploid embryo without fertilization.

What is the difference between apomixis and apogamy?

Who proposed the concept of apogamy?

Apogamy is a unique process of asexual reproduction in ferns, in which the development of haploid sporophyte(n) occurs from a haploid gametophyte(n) without the fusion of gametes. Heinrich Anton de Bary termed this type of asexual reproduction in ferns as Apogamy in the year 1878.

What is the first stage of the sporophyte generation?

In plants, the sporophyte generation is that phase in their life cycle that begins with the union of two single-celled haploid gametes. This union of haploid (n) gametes results in the formation of a single-celled diploid (2n) zygote. The zygote germinates and grows by going through a series of mitotic divisions.
