already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

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 is the alternation of generation?

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 are the alternatives to generating electricity?

The best way to produce electricity is by Solar energy . Solar energy is freely available but only thing is that the implements and instruments used to generate electricity are very costly and they are not much developed. There is also a method to generate electricity ie. by geo thermal energy In (MORE)

How do you explain alternation of generations?

In most plants meiosis and fertilization divide the life of the organism into two distinct phases or "generations".. The gametophyte generation begins with a spore produced by meiosis. The spore is haploid, and all the cells derived from it (by mitosis) are also haploid. In due course, this m (MORE)

Can you make a generator from an alternator?

An automotive alternator is a three-phase generator with a built-in rectifier.Some alternators have permanent magnets that generate electricity as soon as you turn the pulley. Others have a field winding that requires a +12 volt feed via carbon brush to create an electromagnet. Controlling this curr (MORE)

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 i (MORE)

How is alternating current produced in a generator?

In an AC generator an armature is rotated in a magnetic field. This induces an electric current in the armature. if you want more look on the bottom. As the crank turns the armature rotates in the magnetic field. One side of the armature moves up, and the other side moves down. The up and down moti (MORE)

Explain alternation of generation in flowering plants?

Alternation of generation in flowering plants refers to the processof plants alternating between haploid and diploid cells. It beginswith two haploid cells fusing together to form a diploid cell withtwice the amount of chromosomes as the original haploid. They thensplit into diploid sporophytes whic (MORE)

Why does a generator produce alternating current?

i guess only those who study electrical science will ask these questions but why do they ask this kind of stupid questions. its basic electricals it depends on the design whether the generator produces AC or DC generally reffered AC--- Alternator DC----- generator to produce AC supply a simple d (MORE)

How do you convert a 1965 mustang generator to an alternator?

Not much to it, get the one wire alternator, and brackets from a 302 and mount it up, belts will be the same as the 302, wire goes to the battery. # wire is a bit different, red lug goes to battery, botton 2 wire plug should be exciter and is ignition power and a ground.

Summarize the process of alternation of generations?

A sporophyte will produce spores. Spores develop into gametophytes which have one sex (They are either male or female). Gametophytes produce gametes (egg/sperm, depending on sex of gametophyte) The gametes fuse together by fertilization producing a zygote. The zygote develops into the sporophyte and (MORE)

What does a 73 super beetle have an alternator or generator?

I believe the early '73s had Generators and the late '73s had Alternators. It depends on what the previous owners put on? (It may have been the '74s tho.) A lot of people put alternators on for a few more amps. The generators are barrel looking, kinda like a coffee can and the Alternators have a l (MORE)

How power is generated from the alternator?

when electricity travels in a circle, it produces an electromagnetic field. electric motors function by using this property in a reaction of alternating between two or more electric coils which create a field that pushes on magnets inside the casing of the motor. as electricity enters the first coil (MORE)

What are Alternation of generations in ferns and seed plants?

Gen 1 = The plant reproduces sexually Gen 2 = The offspring of that plant reproduce asexually and the cycle begins again, hence the name alternation ---Caveat--- This is a very simple explanation and surely there are exceptions and important details to consider depending on the exact spe (MORE)

What is the significance of alternation of generation?

alternation of generation is very important in plants because it results into the formation of a variety of new organisms... it is also important because it provides such organisms which have more chances of survival...

How alternating current generated?

Describe the alternation of generations cycle?

A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes.
