What is the name given to the life cycle of plants which includes a sporophyte generation and a gametophyte generation?
Plants exhibit alternation of generations that includes both diploid and haploid multicellular stages.The multicellular diploid stage is called the sporophyte and haploid stage is called gametophyte.
In plants that have alternation of generations the haploid spores are made by the?
gametes
What process allows some protists to increase their genetic variability?
1. Asexual reproduction is based on mitosis in eurkaryotic organisms on fission in bacteria and archaea. It results in offspring that are genetically identical to the parent.2. Sexual reproduction is based on meiosis and fusion of gametes. It results in offspring that are genetically different from their parents from each other.3. Sexual reproduction evolved in protists and this evolution ranks among the most significant evolutionary innovations observed in eurkaryotes.4. Alternation of generations: alternation of multicellular haploid (gametophyte) and diploid (sporophyte) forms. When alternation of generations occurs, a spore divides by mitosis to form a haploid, multicellular gametophyte. The haploid gametes produced by the gametophyte then fuse to form a diploid zygote, which grows into the diploid, multicellular sporophyte.
The life cycle of nonvascular plants includes an alternation of generations between a?
diploid sporophyte and a haploid gametophyte
Alternation of generations refers to?
Alternation of generation refers to the life cycles of organisms that alternate between a haploid form that produces gametes that undergo sexual reproduction and a diploid form that produces spores that give rise to the haploid form.
What is the name given to the life cycle of plants which includes a sporophyte generation and a gametophyte generation?
Plants exhibit alternation of generations that includes both diploid and haploid multicellular stages.The multicellular diploid stage is called the sporophyte and haploid stage is called gametophyte.
What term is illustrated by plants that have a sporic life cycle in which both haploids and diploid forms are multicellular?
alternation of generations
Why do humans not go through alternation of generations?
Human beings do exhibit an alternation of generations, but the haploid phase is extremely deemphasized while the diploid phase is overwhelmingly dominant. The haploid phase in humans that results from meiosis is restricted to only one cell, either an egg in the female or a sperm in the male. There is never a multicellular haploid structure as there usually are in plants. If such a multicellular haploid structure is required for a true alternation of generations, then humans do not exhibit alternation of generations. The human organism grows by mitosis (the diploid phase) only after fertilization. A plant sporophyte is diploid and it produces spores by meiosis. Humans, like plant sporophytes, are diploid and make haploid gametes by meiosis.
What is meant by an alternation-of-generations life cycle?
An alternation-of-generations life cycle is a reproductive strategy where an organism alternates between a multicellular diploid stage (sporophyte) and a multicellular haploid stage (gametophyte) in its life cycle. This cycle enables the organism to undergo both sexual and asexual reproduction at different stages.
In plants that have alternation of generations the haploid spores are made by the?
gametes
Do diploid and haploid cells have an alternation of generations or mutations?
Maybe?!?!?!?!?!
What are the 3 types of sexual life cycles?
haploid, diploid, and alternation of generations
Are alternation of generations haploid and diploid all types of sexual life cycles?
True ...
What are the two stage of the plant life cycle?
sporophyte and gametophye. since plants have alternation of generation, both are multicellular (haploid and diploid)

The life cycle of nonvascular plants includes an alternation of generations between a?
diploid sporophyte and a haploid gametophyte
What is a life cycle in which organisms switch back and forth between diploid and haploid stages?
no
