What body system produces diploid and haploid cell by meiosis in humans?
The reproductive system in humans produces diploid cells through meiosis in the process of spermatogenesis (in males) and oogenesis (in females). These diploid cells eventually give rise to haploid gametes (sperm and eggs) which are involved in sexual reproduction.
What does a diploid look like?
A diploid cell contains two sets of chromosomes, one set from each parent. In humans, a diploid cell has 46 chromosomes organized into 23 pairs. This is in contrast to a haploid cell, which has only one set of chromosomes.
How do meiosis 1 differ from those of meiosis 2?
Anaphase of Meiosis 1 separates the homologous chromosome pairs, but during Anaphase of Meiosis 2, the sister chromatids are separated instead. Also, Meiosis 1 starts with one diploid cell and ends with 2 haploid cells, whereas Meiosis 2 starts with the 2 haploid cells and ends with 4 haploid cells (gametes).
How many chromosomes does a strawberry have?
Actually cucumbers have eight-teen chromosomes
How is mitosis and me meiosis different?
Mitosis:is the process of asexual reproduction in eukaryotic cellsGoes through one stageMeiosis:is the process by which a diploid (2n) cell forms gametes (n)Goes through two stages:Stage 1:Late Interphase/ early prophase 1Late prophase 1Metaphase 1Anaphase 1Telophase 1end of meosis1 results in two haploid cellsStage 2:Prophase 2Metaphase 2Anaphase 2Telophase 2End of meiosis 2 results in four haploid cells (gametes) each with no duplicate chromosomes

Is Oocyte haploid?
Unfertilized egg is haploid; but fertilized egg is diploid. That is why you sometimes see chickens even in commercial eggs.
How many chromosomes does a pigeon have?
Okay, so a pigeon has 80 chromosomes when its cells are in the diploid stage. In the haploid stage the cells have 40 chromosomes.
What kind of cells are formed in meiosis?
Meiosis takes place in diploid cells. These are cells which have pairs of chromosomes. For example, in humans there are 23 pairs of chromosomes in the body cells. During meiosis the number of chromosomes is halved, so that haploidcells are produced. These are cells with only one chromosome from each pair. So in humans haploid cells contain 23 singlechromosomes. The haploid cells produced in humans (and other animals) are the sex cells or gametes. These are the sperm cell in males and the egg cell in females. When fertilization takes place the gametes fuse and the diploid number of chromosomes is restored. So the simple answer to your question is egg cells and sperm cells (in humans and other animals). For details of meiosis see http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/M/Meiosis.html However in plants the situation is slightly different. Here meiosis produces haploid spores which germinate to produce a haploid sporophyte. The sporophyte produces gametes by mitosis.

What are the two distinct of meiosis?
I think what you are asking is "What are the two distinct processes of meiosis?"At the beginning of meiosis, there is a diploid cell (chromosomes come in pairs) with duplicated chromosomes (each pair of chromosomes is duplicated). The cell undergoes two processes: Meiosis I and Meiosis II.Meiosis I produces two haploid cells (unpaired chromosomes), but the chromosomes are still duplicated. These two cells then undergo Meiosis II, in which the two haploid cells are split, with one set of unpaired chromosomes going to one and the other set of unpaired chromosomes to the other. The end result of Meiosis II is four haploid cells with unduplicated chromosomes.In short, when a cell undergoes the complete process of meiosis, a single diploid cell with duplicated chromosomes is turned into four haploid cells with unduplicated chromosomes.For a complete description of all the steps along the way, see this page and scroll down about 2/3 of the way: http://en.wikibooks.org/wiki/Adventist_Youth_Honors_Answer_Book/Health_and_Science/Heredity

Where is the anther found on a plant?
A transverse section of the anther reveals four areas of tissue capable of producing spores. These tissues are composed of microsporocytes, which are diploid cells capable of undergoing meiosis to form a tetrad (four joined cells) of haploid microspores. The microspores become pollen grains and may eventually separate.
In which group of plants are both the sporophyte and gametophyte free-living?
In ferns, both the sporophyte (diploid) and gametophyte (haploid) are independent and free-living stages in the life cycle. The sporophyte is the leafy plant we typically see, while the gametophyte is a small, independent structure that produces gametes.
Is the fern unicellular or multicellular?
Fern is multicellular bcz we cant see unicellular organisims and we can see multicellular organism.U now that we can see a fern so t means it is unicellular.from pakistanschool name Joan Mcdonald Schoolwritten by a girl (cant tell u name)
Why did fern's mother go to see doctor dorian in the book Charlotte's Web?
In "Charlotte's Web," Fern's mother goes to see Dr. Dorian because she is concerned about Fern's behavior and her obsession with saving the runt of the pig, which Fern named Wilbur. She wants to understand why Fern is so emotionally attached to the pig and seeks the doctor's advice on how to handle the situation. Dr. Dorian reassures her that Fern's attachment is normal for a child and suggests that she should allow Fern to care for the pig.
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.
