What does atternation of generation mean?
It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation. A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte). It once was called hydrogen power. In more simple terms, it is a life cycle in which there is both a multicellular diploid form, and a multicellular haploid form.
In plant what is the diploid form called?
In plants, what is the diploid form called?
What is a cell with pairs of cromosomes called?
A cell with pairs of chromosomes is called a diploid cell. Diploid cells have two sets of chromosomes, one from each parent.
A diploid cell missing a chromosome is called a?
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
What is alternation of generation?
It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation. A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte). It once was called hydrogen power. In more simple terms, it is a life cycle in which there is both a multicellular diploid form, and a multicellular haploid form.
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)
What is the diploid phase of a plant that produces spores?
The diploid form in a plant's life cycle is called the sporophyte. Land plants have a complex life cycle that involves an alternation of generations between a haploid gametophyte and a diploid sporophyte.

A cell with two of each kind of chromosome?
A cellwith two of each kind of chromosomeis called a diploid cell and is said to contain a diploid, or 2n, number of chromosomes.

A diploid cell missing a chromosome is called a?
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
What is the plant diploid form called?
A sporophyte is the diploid form and a gametophyte is 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.
Alteration of the physical form of a drug outside its label is?
alteration of the physical form of a drug outside its label is called compounding.
What is a Cell that has two copies of each chromosone called?
A cell that has two copies of each chromosome is called a diploid cell. This means that each chromosome in the cell has a matching homologous chromosome. Humans have diploid cells in their body, with a total of 46 chromosomes arranged in 23 pairs.
What are the two stages of plant life?
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.
