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
Which term describes the multicellular haploid form of a protist that shows alternation of generations?
gametophyte
Are alternation of generations haploid and diploid all types of sexual life cycles?
True ...
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.
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.
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
What types of algae show a distinct alternation of generations?
Some types of algae that show a distinct alternation of generations are members of the green algae group, such as Ulva and Spirogyra. These algae have a haploid gametophyte generation and a diploid sporophyte generation. The gametophyte generation produces haploid gametes that fuse to form a diploid zygote, which develops into the sporophyte generation that produces haploid spores.
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 term is illustrated by plants that have a sporic life cycle in which both haploids and diploid forms are multicellular?
alternation of generations
