Alternation Of Generations - Wikipedia
Alternation of generations (also known as metagenesis or heterogenesis) is the predominant type of life cycle in plants and algae.It consists of a multicellular haploid sexual phase, the gametophyte, which has a single set of chromosomes alternating with a multicellular diploid asexual phase, the sporophyte which has two sets of chromosomes.. A mature sporophyte …

Gametophyte Structure And Sporophyte Generation - ThoughtCo
28/4/2018 · A gametophyte represents the sexual phase of the plant life. This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation. The term gametophyte may refer to the gametophyte phase of the plant life cycle or to the particular plant body or organ that …
Bryophyta: Types,Characteristics, Examples, Life Cycle - Embibe
14/11/2022 · The diploid zygote represents the first phase of sporophytic generation. Sporophyte is totally or partially dependent on the gametophyte for nutrition. Sporogenous tissue is divided meiotically to form haploid spores. Haploid gametophyte is produced by the germination of spores. Bryophyta shows a haplo-diplontic life cycle.

16/7/2018 · The moss life cycle is characterized by the alternation of generation, which consists of a gametophyte phase and sporophyte phase. Mosses develop from the germination of haploid spores that are released from the plant sporophyte. The moss sporophyte is composed of a long stalk or stem-like structure called a seta with a capsule
Botany - Wikipedia
Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology.A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word βοτάνη (botanē) meaning "pasture", "herbs" "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν (boskein ...
Moss - Wikipedia
There is a period in the moss life cycle when they do have a double set of paired chromosomes, but this happens only during the sporophyte stage. Life cycle of a typical moss ( Polytrichum commune ) The moss life-cycle starts with a haploid spore that germinates to produce a protonema ( pl. protonemata), which is either a mass of thread-like filaments or thalloid (flat …
Developmental Biology - Wikipedia
The commonly accepted theory for the evolution of plant morphology is the antithetic theory. The antithetic theory states that the multiple mitotic divisions that take place before meiosis, cause the development of the sporophyte. Then the sporophyte will development as an independent organism. Developmental model organisms

In mosses, the sporophyte is the dominant stage of the life cycle; in ferns, the gametophyte is the dominant stage of the life cycle. In both mosses and ferns, moisture is required for sperm to reach the egg. In mosses, the gametophyte is the dominant stage of the life cycle; in ferns, the sporophyte is the dominant stage of the life cycle.
